More recently there has been Great interest in the production of lightweight building components which can be used for the purpose of thermal insulation.The use of such components and buildings have a great advantage and cause great reduction in the energy required for heating and cooling consequently results cost reduction to a great extent , especially prevailing hot dry climatic condition of Iraq. Its thus aimed in this thesis to study properties of two types of polystyrene insulation concrete which can be used for thermal insulation .Such type of lightweight concrete is very needed in...

The research is concerned with a new type of ferrocement characterized by its lower density and enhanced thermal and physical properties such as compressive and flexural strength.The work can be divided into two main parts; in the first part experiments where maid to determine activity index of two types of active pozzolan, namely micro silica ad indigenous calcite and grinded feldspar. Several mortar mixes where prepared to determine the optimum amount of cement and lightweight aggregate (namely local porcelain and polystyrene aggregate). The experiment showed that porcelain are more...
