Performance ability study on sludge contained hollow concrete blocks

ABSTRACT Generation of waste from the consumption of human society at the global level is an increment level day by day. The daily life requirements of the human society start from water consumption, clothes, vehicles for travel, power consumption, drugs etc. The utilization of these facilities by the public leads to different pollution and also generation of waste in different forms. The disposal of the generated waste poses a threat to the human society which needs more attention in the present scenario. Also, utilization of waste results in a sustainability by reducing their environmental footprints and conserving resources. In this article, the sludge generated from the textile industry effluents after its treatment and hypo sludge a waste generated from paper industry were taken for the experimental study. The physico chemical characteristics were analyzed and an attempt was made to utilize the sludge to replace cement in the manufacturing of hollow concrete blocks. The hollow concrete blocks were cast and tested as per the recommendations of BIS standards. The experimental study reveals that about 10% of cement can be replaced effectively for the manufacturing of hollow concrete blocks and possible standards are achieved.
