There is a growing universal awareness of protecting the living and non-living environment and making enlightened decisions to achieve a sustainable development without destruction of the natural resources. In this point of view, selecting building materials according to their energy and health performances gains importance in sustainable design. 3Rs (reducing, reusing, recycling), and supplying a healthy, non-hazardous indoor air for building occupants are two important parameters of environmental life-cycle assessment for materials. Information on exposure to gases and vapors from synthetic materials made from petrochemicals, to heavy metals and pesticides, and to some combustion pollutants that cause acid rain should be determined by analyzing environmental product declarations or material specifications. After studying on building materials individually, they are analyzed in the form of tables for four different stages; manufacturing, application, usage, demolition phase. Consequently, this chapter can guide the designer and engineer to think on the elements of design and construction activity.

Research from the International Energy Agency about indoor ambiences and nearly zero energy buildings (nZEB) in the past has been centred on different aspects such as the prediction of indoor conditions as a function of the weather using laboratory material properties for simulations and real sampled data for validation. Thus, it is possible to use real data for defining behavioural groups of indoor ambiences as a function of real vapour permeability of internal coverings. However, this method is not suitable for modelling it and predicting its behaviour under weather changes, which is of interest to improve the method of selection and use of building construction materials. In this research, artificial intelligence procedures were employed as the first model of permeable coverings material behaviour to provide a newer understanding of building materials and applications for the generation of new control procedures between the mechanical and electronic point of view of building construction materials.

Abstract Abusir is the name of an elaborate burial area, dotted with 19 pyramids other temples, stretching on the western side of the Nile from the south of the Giza Plateau to the northern rim of Saqqara. It seems to have been created as the resting site for the Pharaos dated from 2494 to 2345 BC. The name Abusir, originally spoken as Busiri, means” temple of Osiris”. Over time, the name has become so popular, that more than 60 villages now carry this name. But only one is the archaeological site. This paper does not refer to all of the Abusir archaeological area, but focuses one of its most important sites: Sahure pyramid, one of Egypt’s little known, but heavily damaged treasure. One of the highlights of the relevant research is the discovery of a piece of cement (Basaltic mortar/concrete), which consists of several materials and which is harder than any cement produced today and detection of a clear and significant Anorthite mineral (Plagioclase) in the mortar sample which had been proven by XRD, XRF (analysis) and Polarized light microscope (investigation). The main objectives of this paper are 1) to reveal and identify the construction materials of the pyramid and the construction of the pyramid,2) to evaluate the durability and vulnerability of the Ancient construction materials of Sahure pyramid,3) to compare the decayed patterns of the different construction materials, 4) to study the pyramid building materials from geological, meteorological, geochemical, petrological and petrophysical point of view, and 5) to present a proposal for scientific conservation and protection of the pyramid. Laboratories and field studies have been carried out by researchers from various countries to investigate and understand the problems of the pyramid leading to the final results which confirmed the impact of the geo environment conditions on the structural and engineering stability of the pyramid.

Abstract Construction Industry indicates development of the country and it helps in the economic growth which adds productivity and quality of life of citizens. During the manufacturing and the construction processes, there is use and combustion of fossil fuels which results total 39% of total carbon footprint. So, studying carbon footprint for construction companies becomes very important. Many different studies are carried out with giving number of alternatives to reduce the amount of carbon footprint. However, this research is focused mainly on multi-storeyed residential building in renowned city in India, shows the carbon emissions produced by a construction activity right from the material production to the actual execution process. Different Greenhouse gases contributing carbon footprint were also studied & incorporated. Various activities accounting to emissions were listed and their carbon footprint value (in the form of Carbon Dioxide equivalent) was calculated by bottom-up method. The manufacturing of various construction materials and usage of electricity during execution phases of a building causes very bad impact on the environment. The greatest contributors of the carbon footprint are onsite electricity use and building materials manufacturing. Therefore, use of green concrete, renewable energy, prefabricated construction materials and low emission construction equipment & vehicles can help in reducing the values of Carbon Footprint by the construction industry.

The Impact

The future of the whole world focuses on reducing waste produced by people. As the construction sector is one of the biggest producers of waste, a great deal of effort has been made to introduce this trend in modern construction. The “green” building sector, therefore, draws attention to natural and recyclable building materials. These include natural thermal insulation such as cork, fiberboard, hemp insulation, and even sheep wool insulation. Almost all types of such insulation are made from waste materials which, were they not reused in the form of thermal insulation, would end up as municipal or biodegradable waste. At the same time, we should point out that almost all “green” construction materials are flammable. This feature is not very advantageous from the point of view of fire protection and it can significantly affect the fire safety of a construction. It is for this reason that the main objective of this research was to determine the impact of a radiant heat source on various types of thermal insulation used as plasterboard filling and to evaluate the possibilities of their use in sandwich constructions for fire protection purposes.

Moisture Concentration

This paper compares performances of two wireless sensors for measuring water concentration in building materials, one manufactured by the printed circuit board (PCB) technology and another one using the low temperature co-fired ceramics (LTCC) process. The fabricated sensors consist of inductive part (L) and interdigitated capacitive part (C) in one metal layer, connected in parallel. Inductance of inductive part was kept constant, whereas capacitance of capacitive part was changed by exposing the sensor to different moisture concentration, changing its resonant frequency. The variation of resonant frequency as a function of different water concentration was measured, using antenna coil and impedance analyser, in two widely used construction materials: clay brick and autoclaved aerated concrete block. Surface analysis for two sensors was performed by means of 3D profilometer. Mechanical properties of the sensors were measured for both conductive segments (copper and silver) and substrates materials (PCB and ceramics substrates) using nanoindenter. Comparative characteristics of the sensors are presented from their application point of view.

The article actualizes the importance of the development of the construction materials industry in the Russian Federation from the point of view of the need to level the existing imbalances in the socio-economic development of the regions. The main trends, problems and prospects of development of the construction materials industry are analyzed on the materials of the Republic of Bashkortostan – one of the leading subjects of the Russian Federation. In the 1990–2000-ies of economic reform in the construction complex of the country were destroyed centralized management structures, deformed industry and spatial structure of the complex, violated the relationship between suppliers and consumers of building materials and structures, which led to the bankruptcy of most of the largest construction trusts, reducing the volume and pace of construction and installation work. In the Republic of Bashkortostan, the share of private construction companies has increased with a decrease in the share of state-owned enterprises and enterprises of mixed ownership. Due to the crisis situation of a number of Republican manufacturers of building materials, the volume of unfinished construction is growing, the needs of the region in construction materials and structures are not covered sufficiently. The results of the analysis of development of construction complex of the region and substantiates the need for structural and technological modernization of the industry of construction materials based on the structural transformation of the economy of the region, introduction of the latest scientific and technical achievements, advanced machinery and technological processes, effective structural changes and institutional reforms. Taking into account the advanced foreign and domestic experience (Moscow, Moscow region, St. Petersburg, Sverdlovsk, Voronezh, Kaluga, Lipetsk, Novosibirsk, Samara, Saratov regions and the Republic of Tatarstan), the priority directions and mechanisms of structural modernization of the construction materials industry of the Republic of Bashkortostan through the use of the cluster approach are scientifically justified.
