In India, it is estimated that out of 125 million tones (Mt) of stone aggregate produced every year, 17.8 Mt is crushed rock dust (CRD) which is presently used for land filling causing environmental problems such as loss of fertility of soil. This paper deals with the use of CRD as filler material in producing concrete.
Utilization of stone crusher dust (SCD) is also a challenge for the stone crusher owners. So, this study utilized C&DW and SCD in paver block manufacturing. Mechanical & durability performance i.e. density, compressive strength, split tensile strength, water absorption, abrasion resistance & ultrasonic pulse velocity were evaluated.
