Today, the expenditures for the prevention of energy loss are higher than ever. In this study, in the aim of reducing the investment cost and ensuring long term profit; the extenuated silisium plaster which is used for heat, sound, water and fire insulation will be introduced. Although, it has a low awareness level in building sector; “the extenuated silisium plaster” is an insulation material, that provides A1 Class incombustibility, 18 decibel noise insulation at 2cms thickness and 500Hertz level, 1/12 weight in comparison with classic plaster and water insulation with hydrophobic feature.

Increasing population and water demand in our country significantly reduces the amount of water per capita due to the limited availability of available water resources. For this reason, water sustainability is important to protect our water resources and to get optimum use of them. In urban areas, where there are more often impervious surfaces, it is necessary to make more use of rainfall and increase permeability. The solution is to use sustainable urban drainage systems (SKDS) Swales are an environmentally friendly SKDS application that infiltrate to groundwater by storing rainwater and thus feeds groundwater sources. At the same time, swales contribute to increasing water quality and biodiversity. As a result of literature study; dry swales should be used in settlements and wet swales in rural areas. In order to obtain maximum benefit from the swales, its longitudinal slopes should be between 1% and 4%. Also swales should be built as trapezoidal or parabolic cross-sections. In this study, the types, advantages and disadvantages of swales, their performances and applications in world and our country are explained and aimed to spread the usage of swales in our country. Wet and dry swales were compared to traditional rainwater drainage systems. In this comparison, it has been observed that the swales have very large advantages according to the traditional rainwater drainage systems. For this reason, it is proposed that the swales should be used widely spread together with or without traditional systems.

Because of the developing materials and production technologies and the resulting densereinforced building elements, the use of Self-Compacting Concretes in building sector is increasing day by day. In this study, we present the studies that show the aggregate effect on the performance properties of Self-Compacting Concrete. As a result, there is a need for more detailed studies that cement paste and aggregate connections in self-settling Concrete, which are widely produced with local resources, and those studies are being carried out in relation to the mineralogical and petrographic properties of aggregates.

In chrome quarries, precious minerals in the structure of low-grade ores are separated by means of ore preparation or mineral enrichment method, and they are collected and highgrade concentrates are supplied to the industrial area. In the facilities that produce chromium by this method; 10% of the recovered ore entering the enrichment facility is separated as concentrate ore and 90% as mineral enrichment waste. This significant amount of waste is stored idle; the plant occupies large areas and creates pollution in nature visually and physically. It is considered to investigate the use of chromium metal waste in the area called FethiyeKöycegiz-Denizli-Burdur region as aggregate in the production of foam concrete. It is aimed to determine the advantages of using foam concrete as building material, to reducing the production cost of foamed concrete, to create alternative solutions for rehabilitation and to destroy environmental pollution in the field. In this study, compressive strength experiments were carried out according to TS EN 1354, thermal conductivity experiments were carried out according to TS EN 12664. As a result, it has been observed that chromium waste can be used under certain conditions in the construction of foamed concrete.
