| Abstract | ||
| The weather in Iraq is hot in summer and cold in winter. Therefore , the thermal insulation is of the main problems facing the engineers working in building and housing sector The paper presents an experimental investigation, It includes preparation of several concrete mixes using lightweight aggregate (siporex and porcelinite & suwdast ) to obtain light weight concrete of two densities ranging from (350-880 kg/m3), which provides a good thermal insulation. Based on the analysis of experimental results several graphs and Tables have been prepared and presented which can be used in the mix design of similar siporex concrete of densities from (350-880 kg/m3) . The physical properties of siporex concrete , have been found which included density (765-822kg/m3) , compressive strength (1.51-2.2 N/mm2) & (2.8-3.7 N/mm2) ,thermal conductivity ( 0.19-0.39 W/M.K) for the two groups respectively. | ||
