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

Abstract

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