| Abstract | ||||
| Nowadays, we are facing with the high consumption of raw materials by the construction sector, results in chronic shortage of natural building materials and the associated environmental, Building materials manufacturing is usually accompanied by wastes as by products such as marble waste, which adversely affects the surrounding environment from healthy side and may affect the geometric properties of the soil. Recycling of marble wastes has actually environmental, economic and technical benefits. In Egypt, the studies to utilize the marble wastes are an important issue because a large amount of this waste has been throwing to the public places and in illegal places. Mentioned several studies for some researchers have proposed reutilizing this waste in building elements, such as concrete or paving block or bricks. It is possible to find a lot of researches in mechanical and physical properties while little effort has been made to characterize recycled marble waste in hollow concrete blocks for their thermal properties. The aim of this study was to characterize and study influence of marble waste as partial replacement material for coarse aggregate, sand and cement in the hollow concrete block thermal conductivity in order to provide subsidies for a building's thermal performance analysis. The simulation results focused on the evaluating the thermal performance of building as an example of residential agglomerations, this model for house were constructed using four types from hollow concrete block of materials different. The results indicated that the concrete blocks overall thermal conductivity in the solid region was within the intervals of 0.93, 1.34, 1.03 and 1.36 W/m.K respectively. | ||||
