There are many reasons for today’s environmental problems of today, the most important of them are the rise of construction industry based on population growth and and the increase of the waste that is generated by the growth of this sector. In particular, the amount of energy used in the production and application of the materials in constructions is one of the most important causes of the climate crisis that threatens our world. On the other hand, the emergence of designs compatible with nature to reduce the negative impact on nature has brought sustainability to the agenda. Ensuring the effective use of sustainable materials is one of the most important steps in this way. In the context of sustainable materials, stone material, which is frequently used in our traditional architecture has been addressed. Within the scope of this study, modern buildings which include locally sourced stone materials, were examined. The preference of local materials as building materials allows elimination of the energy which is consumed during material transportation and the carbon emission it creates. It is also valuable in terms of efficient use of energy and contributing to the local economy. A literature review has been made on sustainable architecture, sustainable use of materials and stone materials discussed within the scope of the study. According to that; "B2 House" and "Gökçeada High School Campus" buildings were examined in terms of local material usage. These structures are built with the support of the stone material offered by the geography, respectful to the traditional structure, and at the same time accommodating the requirements of modern life. The aim of this study is to reduce the energy consumption by encouraging the use of local materials in buildings in rural areas and to enable these structures to set a precedent for other buildings. With the development of technology, many unsustainable construction methods have emerged. As an alternative to these methods, it is aimed to increase the use of architectural methods compatible with nature. Acting in this direction, sustainability will provide gains in many areas. It is predicted that it will contribute to the local economy as well as adapting to nature. Key Words: Sustainable Architecture, Sustainable Material, Local Resource Usage, Local Stone Material Usage.

Study Context

Enhancing the employability of National Certificate (Vocational) NC(V) graduates in South Africa is important. If NC(V) graduates are not employable, this has a negative impact on both the local economy and the future prospects of these young adults. Yet, national data show high youth unemployment rates which includes those with NC(V) qualifications. The factors that influence the employability of these graduates – particularly in the rural areas of South Africa – are not well documented. This study therefore explored the factors that influence NC(V) graduates’ employability by means of a case study at a rural TVET college in the Eastern Cape province of South Africa. The case focused on recent NC(V) graduates’ perceptions of their own employability and also on input from lecturers in selected NC(V) programmes and potential employers in the study area. Semi-structured interviews were conducted. The findings indicate that negative stakeholder perceptions exist about the employability of NC(V) graduates in the study context, which was a major factor in determining these graduates’ employment prospects. Furthermore, there have been no attempts to strengthen relations between the particular vocational institution and the local employment industry included in the study. The TVET college was hampered by poor planning, while prospective employers had limited awareness of the NC(V) curriculum and its objectives. These factors underscore the dissatisfaction among rural stakeholders with the employability of NC(V) graduates in the study context.

The paper presents the history of the transport infrastructure of the West-Siberian oil and gas complex in the last century and ways to solve the problems of road construction in the twenty-first century. The development of the territory of Siberia and the North in the present period is constrained by the low rates of development of the transport structure. One of the reasons for this lag is the lack of regulatory documents to substantiate transport structures in the harsh climatic and difficult soil and geological conditions based on the use of new modern road-building materials. The development of new resource-saving materials, structures and technologies based on local building materials, products and industrial waste using modern methods and research methods in materials science is an aim of current study. The general research methodology consisted of theoretical, laboratory and field studies. The developed designs and technologies for the construction of embankments in permafrost and in swamps using geotechnical holders filled with unsuitable soils (thawed and frozen waterlogged peat and clay soils) can reduce the volume of work and the cost of construction by one and a half to two times while increasing the service life of structures. The experimental sites of embankments constructed between 1995 and 2009 in the wetlands of the Uvat Group of deposits in the Tyumen Region and in permafrost in the areas of Novy Urengoy have been observed for more than ten years. The artificial stone material tested in Murmansk and Surgut based on the strengthening of local soils with inorganic binders with polymer additives using modern technologies allows it to be used instead of imported stone materials and reinforced concrete slabs for the construction of structural layers of road pavements, reinforcing slopes, as well as in hydraulic structures. The new artificial stone material is characterized by high strength and durability in areas with a temperature gradient of the external environment of more than 100 (from +50 to -50 °C).

It has been the consensus shared by every member of the society that we should protect the earth, benefit the future generations and take the road of sustainable development which is natural-based and coordinated with environment carrying capacity. Currently, no one can doubt the importance of low carbon living and low carbon architecture. Numerous new materials and high technologies have been used in the country all over the world in the course of low carbon architecture’s development, some of which has had a favorable result, such as London zero carbon emissions pavilion at the 2010 Shanghai World Expo. But China still is a developing country, for various reasons, it is premature to widely promote the expensive high-tech low-carbon buildings, and especially in the vast rural areas, the traditional local materials and suitable technology still could have general applicability. This paper takes the rammed earth building as example, by introducing the history of rammed earth building, the application status and some of the latest instances, and summarizes several advantages of rammed earth building: the first is that easy manufacturing processing could reduce the energy consumption; the second is that local materials could lower transportation costs; the third is that the clay materials with good thermal performance such as heat insulation and moisture property could ensure comfortable indoor environment, the last is that long service life and easy reclamation could recycle building materials. Then the author looks forward to the future development trends of rammed earth buildings, explores the new construction practices of rammed earth buildings. Finally this paper concludes that traditional local materials and suitable technology would play an important role in the modern low-carbon architecture.

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

Indoor air quality can be adversely affected by emissions from building materials, consequently having a negative impact on human health and well-being. In this study, more than 30 natural building materials (earth dry boards and plasters, bio-based insulation materials, and boards made of wood, flax, reed, straw, etc.) used for interior works were investigated as to their emissions of (semi-)volatile organic compounds ((S)VOC), formaldehyde, and radon. The study focused on the emissions from complete wall build-ups as they can be used for internal partition walls and the internal insulation of external walls. Test chambers were designed, allowing the compounds to release only from the surface of the material facing indoors under testing parameters that were chosen to simulate model room conditions. The emission test results were evaluated using the AgBB evaluation scheme, a procedure for the health-related evaluation of construction products and currently applied for the approval of specific groups of building materials in Germany. Seventeen out of 19 sample build-ups tested in this study would have passed this scheme since they generally proved to be low-emitting and although the combined emissions of multiple materials were tested, 50% of the measurements could be terminated before half of the total testing time.

The main aim of this paper is to demonstrate that clusters can support the sustainable development of rural areas through the creation of shared value. This is done via the close exam-ination of six different cases of rural clusters in Greece, Italy, Germany, Poland, Denmark, and Sweden. Qualitative as well as quantitative data weretaken from the clusters, which demonstrated that their main business approaches naturally coincided with the creation of economic, social, and environmental benefits for the local communities in which they operated. The case clusters were created in a top-down manner, aimed at boosting regional R&D activities and making the local economy more competitive and more sustainable. However, private initiative took over and al-lowed these clusters to flourish because meeting the regions’ economic, social, and environmental needs successfully coincided with the target of the clusters’ own development and profitability. The results show that clusters, with their potential for shared value creation, can constitute a powerful engine for the revitalisation and development of rural areas, addressing the significant challenges which they are currently facing.

Introduction. Growing volumes of road construction increase the need to expand and rationally use of raw materials. The need for stone materials can be solved through the wide spread using of local materials, recycled products of industry in the pavement base courses and decreasing the use of natural construction materials by replacing them with alternatives, including soils, slag materials that are metallurgical industry wastes. Experience of ferrous metallurgy slag usage has been accumulated in the road industry of Ukraine. Their usage makes it possible to extend the construction season, increases the strength and reliability of road structures due to their physical and mechanical properties, significantly reduces the road pavement energy consumption, simplifying the technology of works and the estimated cost of road construction. It was determined that the layers of pavement made from blast furnace slag have a high bearing capacity. Slag structures in 5–10 years of hardening are not inferior to, and in 10–20 years surpass cement structures on durability and deformation resistance. However, there is an urgent need to provide strength and open road traffic on the already built road section in a shortest possible term, so there is a need to accelerate the activation of the slow-setting binder. Therefore water glass (water solution of sodium silicate) is used.Purpose. The purpose of the work is to study the feasibility of using the soils and recycled industry products treated with water glass in the road pavement base courses.Materials and methods. Experimental tests of soils and blast furnace slags treated with water glass with different content of water solution of sodium silicate were performed.Results. The feasibility of using the asphalt concrete mixtures on the basis of soils and recycled products of industry treated with water glass in the pavement base courses is determined. Recommendations regarding technological parameters of preparation, transportation, laying and compaction of such mixes are given.Conclusions. Performed studies have shown that the physical and mechanical parameters of soils and blast furnace slags treated with water glass meet the requirements of current regulations of Ukraine. The advantages of use are noted, namely: the possibility of replacement of traditional stone materials by the local materials and recycled products of industry, reducing the transport component in the cost of construction. The obtained results indicate the feasibility of using the soils and recycled products of industry treated with water glass in the road construction.Keywords: soils, recycled products of industry, graded blast furnace slag, water solution of sodium silicate, water glass

Effective utilization of ash-and-slag waste generated by coalfired power plants can help significantly to reduce the negative impact on the environment and improve their economic performance. Studies have been made of the mineralogical composition of ash-and-slag wastes obtained after the combustion of water-coal fuel based on fine-dispersed coal-washing waste (filter cake) in a specially designed boiler with a vortex combustion system. The possibility of effective use of ash-and-slag wastes for the production of building materials, primarily mortar mixes, widely used for mining works on mine openings, laying the worked out space, etc. (high content of silicon oxide and aluminum oxide is combined with a low carbon content in other words a negligible unburned carbon loss). The optimum percentage ratio of the initial components of the filling mixture based on ash-and-slag wastes and crushed rock (granulated slag) has been established. The results of experimental tests of hardening tabs on the strength under uniaxial compression are presented. It has been established that a sample containing 18% of ash-and-slag wastes, 33% of a granulated slag and 19% of cement, corresponds to the required technological parameters for the strength and cement content.
