Cool concrete facades produced from waste materials

Öz

Human comfort inside or outside of the houses has been related also with surrounding temperature. Concrete masses used in urban areas influence surrounding air temperature due to their heat storage properties. Due to surrounding air temperature they absorb or supply heat energy through conductions, convention or radiation manners. Sun heated solid masses in cities mainly; roads, roofs, buildings’ external walls, parking lots etc. have therefore influenced urban air temperatures. Heat energy originated due to radiation waves of sun have been accumulated on surfaces of those solid materials and then excess heat is ready to be transferred to surrounding environments (solids, liquids, gasses). That is, excess heat accumulated on concrete facades or concrete structural elements cause temperature increase around them until their temperatures have been levelled. This is favourable in winter (cold weather) for inside comfort of houses, but, it is disturbing in summer (hot weather) times. Small concrete facade samples had been prepared in this study to define their differences in heat energy storage capacities. Cool facade test samples were studied by preparing them by using raw materials; acidic & basic tuffs, fine waste materials from marble & travertine dimensioning facilities, cement factory fine size wastes, and fly ashes of power plant to observe their heat accumulation characteristics.
