Use of recycle paper mill residue and fly ash in production of waste-create bricks

Abstract

Accumulation of unmanaged industrial solid waste, especially in developing countries has resulted in an increased environmental concern. Resource recovery and utilization of industrial by-product materials for making construction material has gained significant attention across the world. In this research study, recycle paper mill residue (RPMR) and fly ash (FA) are utilized to improve the properties of bricks. This research study evaluated the feasibility of utilizing RPMR and FA for making construction bricks. A homogeneous mixture of RPMR-FA-cement was prepared with fixed content of RPMR (50% by weight) and varying amount of FA (30-50% by weight) and cement (0-20% by weight). The waste-create bricks were developed from the homogeneous mixture of RPMR-FA-cement and tested in accordance with the IS codes. Characterization of RPMR and FA was performed. The SEM monographs show that RPMR has a porous and fibrous structure. The TG-DTA characterization demonstrated that RPMR can withstand temperatures up to 280 oC. The results indicate that RPMR- bricks prepared from RPMR-FA-cement combination are light weight and meet compressive strength requirements of IS 1077-1992. This novel construction material serves objectives of resource recovery through prudent solid waste management
