The Environmental and Economic Impact of Recycling Printing Paper in the Concrete Industry

Abstract

Iraq faces a serious challenge in disposing of waste in many landfills throughout the country. Due to the high costs of disposing of this waste, potential environmental problems, and the effort and time expended on it. In this research, paper waste that was taken from schools, libraries, and from paper shredders was used in concrete mixtures for use in construction projects. In this research, paper pulp was used as a replacement material (5%, 7% and 10%) of cement fraction in concrete mixtures. The weight mixing ratio used in conventional concrete was (1:1.6:2.37) of cement, sand and gravel respectively with water to cement ratio (0.48). Workability, dry density and thermal conductivity tests were carried out using standard samples at ages (7, 14 and 28) days..
