Purpose This study is part of the valorization of local materials and the reuse of industrial waste in construction. This study aims to improve the physical-mechanical properties of sand concrete. This work is a continuation of previous studies conducted on sand concrete, the purpose of which is to introduce industrial waste into this material. For this purpose, a glass waste in powder form is added. Design/methodology/approach This study is focused on the effect of adding glass powder (GP) whose mass percentage varies from 0 to 40% with an interval of 10% to target the right composition that ensures the best compromise between the characteristics studied. Findings The results found show that the workability and density of the studied concretes decreased with increasing GP dosage. Indeed, the optimal addition which constitutes the best compromise between the studied properties is 10% of GP. Improvements of up to about 9% in the case of flexural strength and about 18% in the case of compressive strength. The thermal conductivity has been reduced by 12.74%, the thermal diffusivity which characterizes the notion of thermal inertia has been reduced by about 4% and the specific heat mass has been reduced by 7.80%. Also, the shrinkage has been reduced by about 20%. The microstructure of the studied composite shows a good homogeneity between the aggregates. Finally, the addition of GP to sand concrete gives very encouraging results. Originality/value The interest of this study is in two parts. The first one is the exploitation of local materials: dune sand, river sand and limestone filler to meet the growing demand for construction materials. And the second one is the reuse of glass waste, in the form of powder (GP), to solve the environmental problem. All this participates in the improvement of the physical-mechanical properties of sand concrete and the extent of its response to the development of an economical structural concrete.

Concrete is one of the construction materials of combination between cement, fine aggregate, coarse aggregate, and water mixed into one solid mass. The work of concrete making can be added a mineral additive as well as chemical additive (admixture) for the interest in construction work. In some cases construction work is desirable for concrete to produce optimum strength during the early age of the concrete so that the timing of concreting work can be shortened. The strength of concrete at the early age can be increased with added mineral (additive) and chemical (admixture) materials. This research made a mixture of concrete with 7 variations of mixture with total specimen 54 sample of cylindrical size with diameter 15 cm and height 30 cm. Tests conducted in the form of testing workability and compressive strength of concrete at the age of 3 days, 7 days and 28 days. Through this study obtained the right composition to make concrete with a high early age of compressive strength.

Instant noodles have become a very common food in recent years, and because of its convenience and affordability, it is now one of the most profitable products in the food industry. While it is a very convenient food product to carry around, its packaging tends to be inconvenient and not eco-friendly. The packaging of instant noodles can be categorized into two different types: The first is small, and very light, packed in plastic bags, requiring that customers supply their own bowl in order to enjoy the food; the other is packed in a paper, or Styrofoam bowl, usually with additional space in the bowl for customers to add water. The dimensions of the bowl make it less portable, and the construction materials are not eco-friendly. We build a model design that combines the benefits of each packaging type (Fig.2). The size remains as small as the plastic bag type, while simultaneously having the expandable space of the bowl type. The proposed model is made compact during shipping, but its foldable design allows the customer to readily reconstruct it into a bowl for use. Using recycled paper and PE film for materials, we have ensured that, with the use of special recycling technology, the packaging is 100% recyclable. The result is an eco-friendly, light, and purposeful design.

Bacterial Concrete

The right selection of building materials plays an important role when designing a building to fall within the definition of sustainable development. One of the most commonly used construction materials is concrete. Its production causes a high energy burden on the environment. Concrete is susceptible to external factors. As a result, cracks occur in the material. Achieving its durability along with the assumptions of sustainable construction means there is a need to use an environmentally friendly and effective technique of alternative crack removal in the damaged material. Bacterial self-healing concrete reduces costs in terms of detection of damage and maintenance of concrete structures, thus ensuring a safe lifetime of the structure. Bacterial concrete can improve its durability. However, it is not currently used on an industrial scale. The high cost of the substrates used means that they are not used on an industrial scale. Many research units try to reduce production costs through various methods; however, bacterial concrete can be an effective response to sustainability.

The considerable network of transportation infrastructures such as highways, rails, and so forth are key providers to economic growth and productivity of countries. Consecutively, Reinforced Concrete (RC) is the predominant construction materials in constructing many of these infrastructures. RC is a unique construction material which allows flexible design layouts and offers safe bending and torsion to satisfy design requirements. However, being exposed to harsh environment and contamination such as salts, acid rain, distilled water, carbonation, sulphur and so on are the reasons for deterioration, thus significantly impacting the performance of these structures. Furthermore, the deterioration of these structures is not only a safety issue, but also an economic concern. Moreover, deterioration of concrete infrastructures can be attributed to many factors from structural deficiency to corrosion of reinforcement and thermal expansion due to fire damage. Accordingly, this paper will review the corrosion of reinforcements in concrete transportation Structures, and in doing so it will also examine some of the novel deterioration models to prolong concrete transportation structures.

Introduction. In 1971, “Schedule of multi-purpose use and protection of water resources of the basin of the Belaya River” envisaged construction of a cascade of 10 waterworks facilities, subdivided in 4 sections. Nizhne-Suyanskiy Waterworks Facility was planned for construction in the third section, the most lucrative in terms of energetic utilization. However, of the three HPPs planned in this section: Varyazhskaya, Nizhne-Suyanskaya and Pavlovskaya HPP, for the time being, only Pavlovskaya HPP has been built. Nizhne-Suyanskiy Waterworks Facility had the mission to solve water household, energy and socio-economic problems. Materials and methods. Initial material for the study were the results of the “Substantiation of the investment in the construction of Nizhne-Suyanskiy Waterworks Facility in the Ufa River in the Republic of Bashkortostan” prepared by ОJSC Energy Engineering Centre of Volga Region. Based on the retrieved data, the following analyses were made: a theoretical analysis, an estimate substantiation; subsequently, conclusions were put down based on the obtained results. Results. The optimum solution is a comprehensive waterworks facility, since Nizhne-Suyanskaya HPP will allow for improvement of the electrical power supply of the consumers of the NE part of the Bashkir power supply network. The construction of Nizhne-Suyanskiy Waterworks Facility will enable the control of the water influx to the water storage basin of Pavlovskaya HPP allowing for its increased generation power. The construction of the waterworks facility is supposed to carry out in 2 stages. The first stage will be the erection of a concrete overflow weir as a single unit with the HPP building. The second stage will be the construction of a soil dam of local construction materials, that is: dam body of sand and gravel soil, PFU core of loamy soil. Simultaneously with the soil dam, on the right bank a solid blind concrete weir will be erected. Conclusions. Nizhne-Suyanskiy Waterworks Facility unfortunately was not built. Feasibility studies have demonstrated a rate of return of the waterworks facility of 12.8 %, the value being a little higher than the standard one. This justifies investment in Nizhne-Suyanskiy Waterworks Facility. The basic feasibility factors of the construction of the waterworks facility are: Federal support, project engagement of the executive authority of the Republic of Bashkortostan and PJSC RusHydro, as well as availability of free investment funds.

Установлено, что на пути развития строительных организаций существуют проблемы, связанные с финансовыми рисками, а также необходимостью соблюдения экологических требований к строительным материалам и самому строительству. Цель исследования заключается в теоретическом обосновании степени влияния механизма саморегулирования на процесс снижения уровня экологических и финансовых рисков в строительных организациях, что является актуальной задачей. Доказано, что вопросы совершенствования механизма саморегулирования оказывают существенное влияние на динамику рисков в сторону их снижения. Административная реформа, которая начата в Российской Федерации, позволила сформировать институты саморегулирования, позволяющие существенно снижать уровень совокупных затрат в отрасли и уменьшать экологические и финансовые риски. Установлено, что саморегулируемые региональные организации (СРО) России получили дополнительные права в сфере осуществления контроля закупок строительных материалов, что позволит снизить уровень затрат и заставит строительные организации закупать материалы, прошедшие экологическую экспертизу. СРО наделили правом контролировать стандарты на процессы выполнения работ и утверждать квалификационные стандарты специалистов в области архитектурно-строительного проектирования. Предложен комплекс мер по совершенствованию взаимодействия саморегулируемых региональных организаций России с государственными органами и муниципалитетами в вопросах их активного участия в реализации политики государства в области градостроительства и внедрения механизма государственно-частного партнерства в формировании городской среды, а также ликвидации ветхого жилья. It is established that there are problems associated with financial risks, as well as the need to comply with environmental requirements for building materials and construction itself, on the way of development of construction organizations. The purpose of the study is to theoretically substantiate the level of influence of the self-regulation mechanism on the process of reducing the level of environmental and financial risks in construction organizations, which is an urgent task. It is proved that the issues of improving the self-regulation mechanism have a significant impact on the dynamics of risks in the direction of their reduction. The administrative reform initiated in the Russian Federation has allowed the formation of self-regulatory institutions that significantly reduce the level of total costs in the industry and reduce environmental and financial risks. It is established that self-regulating regional organizations of Russia have received additional rights in the field of control of procurement of construction materials, which will reduce the level of costs and force construction organizations to purchase materials that have passed environmental expertise. SRO was given the right to control the standards for the processes of work and approve the qualification standards of specialists in the field of architectural and construction design. A set of measures is proposed to improve the interaction of self-regulating regional organizations of Russia with state bodies and municipalities in matters of their active participation in the implementation of state policy in the field of urban planning and the introduction of a mechanism of public - private partnership in the formation of the urban environment, as well as the elimination of dilapidated housing.

The Impact

Good materials management on large construction projects is critical for maximizing productivity and project performance. When key materials are temporarily lost, whole crews may be left idle and the project may be delayed. When key materials are completely lost, the impact can be enormous. In fact, one of the major problems in managing construction materials and equipment is tracking them in the supply chain and knowing their location on large job sites. Fortunately, location can now be automatically estimated within metres using emerging technologies. This paper proposes a general implementation model for automated construction materials tracking and locating on large industrial projects, such as refineries and power plants. It includes a methodology for determining what type of technology should be used for different types of projects and construction materials. It is based on an analysis of the capabilities of emerging technologies and on experience gained from implementing automated materials tracking prototypes on two large industrial projects. It is concluded that these technologies can produce substantial net benefits, if implemented properly on the right projects using the model described here.

SummaryRecently, there has been a proliferation of international agreements imposing minimum standards on states in respect of their treatment of foreign investors and allowing investors to initiate dispute settlement proceedings where a state violates these standards. Of greatest significance to Canada is Chapter 11 of the North American Free Trade Agreement, which provides both standards for state behaviour and the right to initiate binding arbitration. Since 1996, four cases have been brought under Chapter 11. This note describes the Chapter 11 process and suggests some of the issues that may arise as it is increasingly resorted to by investors.
