Use of Textile Waste as an Addition in the elaboration of an Ecological Concrete Block

Abstract The textile industry has grown significantly in recent years, reaching a global fiber production of 53 million tons which 12 % are recycled; Construction sector been using more and recycled materials from different industrial sources, to apply them their constructions reduce CO 2 emissions final energy consumption. present study aims the behavior concrete blocks f´ c = 210 kg/cm adding polyester waste with 3 %, 6 9 15 %; void content, compressive strength thermal conductivity decrease, water absorption, acoustic insulation unit price increase by 34 16 compared conventional block.
