“…No matter of the form in which it is used (simple, slightly reinforced or prestressed) the concrete represents the most utilized construction material of this end of millennium, and the prognosis studies indicate it as principal favourite of the constructors in future, as well [1][2][3][4][5][6][7][8][9][10][11]. If in the last century, at the world level, the average amount of concrete consumed per capita of people was of about 0.75 m 3 , for the year 2012 this amount was 1.6 m 3 .…”

Abstract. The aim of the study is to show the improvements on durability of prestressed concrete elements by introducing in concrete mass a certain quantity of fibres. Random distributed fibres provide a significant increase in the tensile strength, having also favourable consequence on other mechanical and durability characteristics. The prestressed concrete elements are under a permanent stress state that is not optimal in all their sections and zones. One of the most unfavourable effects is the reduction of material durability, especially in aggressive environments, in which prestressed reinforcements are more sensitive to utilization than reinforced concrete components. The authors present the result brought up by the use of steel fibres in the improvement of the durability of concrete elements, in relation with the volumetric steel ratio, and the geometrical ratio of steel fibres, leading to a favourable effect on prestressing efficiency.

“…The research community has made significant efforts to identify alternative renewable building materials and minimal technologies that result in more sustainable and economical construction that meets today's comfort requirements (Usman et al, 2012). From an environmental standpoint, developing and implementing innovative, efficient technology and goods with improved manufacturing process parameters is important to reduce energy use and the use of raw materials (Vasilache, 2010). Thermal quality enhancement in buildings by thermal insulation is critical for sustainable development (Diakaki et al, 2008;Galvin, 2010;Lopes et al, 2005).…”

One of the significant Malaysian building development issues would be overheating building space as the common building materials are unable to control thermal absorption in the building. Basedon Malaysia Standard Department 2007 guideline, the recommended temperature for interior design environment in Malaysia should be between 23ºC and 26ºC. Because of its area located at latitude 4.2105° N and longitude 101.9758° E, Malaysia gets the sun almost every day throughout the year. A significant heat increase in Malaysian houses gets from building elements. Therefore, this situation is because the common building material cannot control the thermal absorbent into the building. Laboratory analysis was conducted to determine the feasibility of developing a low-cost building material with acceptable thermal properties. The thermal performance of the used waste rubber was investigated to produce the new insulation building material (WRWP). Waste rubber from tyre production was used in this study. 700 grams of waste rubber was mixed with 400 grams of adhesive glue for every wall panel. Installing WRWP helps to decrease 28% of indoor temperature compared to buildings without WRWP. It also helps to slow downthe heat increase when the temperature outside the building increases. WRWP installation also accelerated internal temperature when the temperature outside decreases.

“…The results revealed that one-layer model can be used to measure the heat storage potential by using an inflated mass density of the same magnitude as two times the mass density. Vasilache et al [13] aimed to suggest new constructive solutions for buildings thermal insulation which contributing likewise to protecting the environment and cost savings. For this aim, the authors used bulk materials including sawdust, hacked paper, crumbled expanded polystyrene, PVC recipients.…”

Since concrete is one of the most popularly utilized building mixtures in construction, a high demand of natural resources is significantly emerged. Therefore, a skyrocketed attention has been paid to create new opportunities for the use of recycle materials to develop a new construction substance with more satisfactory properties. The use of waste products in concrete is not only economical, but it helps in solid waste management as well. Among various properties of concrete, thermal conductivity is a crucial factor that plays an important role in in building insulation by evaluating a material's capacity to transfer heat. This paper aims to review the potential application of waste materials in concrete as additive ingredients and investigate the effect of this waste material on thermal conductivity of concrete. The review of literature revealed that the application of most of the waste materials exhibited an obvious potential as thermal insulator. However, further investigated work is needed to highlight the advantages of utilizing waste materials in concrete containing various type of waste materials K ey w ord s: Concrete, fresh and mechanical properties, thermal conductivity, waste material
