The Partial Replacement of M-Sand With Ceramic Waste Sand

Abstract

This study explores the feasibility and effects of partially replacing manufactured sand (M-sand) with ceramic waste in varying proportions (10%, 20%, 30%, 40%) within M-30 grade concrete mixes. The construction industry increasingly seeks sustainable alternatives to natural sand, prompting the investigation of ceramic waste, a byproduct of ceramic manufacturing, as a potential substitute—experimental work involved substituting M-sand with ceramic waste at different replacement levels, ranging from 10%-40% substitution. Critical factors like compressive strength, flexural strength, workability, and ultrasonic pulse velocity were measured to assess the performance of the blends. The findings show that ceramic waste can significantly enhance specific properties of concrete and mortar. Optimal replacement levels were identified, showing improvements in mechanical strength while maintaining acceptable workability. The study concludes ceramic waste is a viable alternative to M-sand, contributing to sustainable construction practices by reducing the dependence on natural sand resources and minimizing industrial waste.
