Effective Utilization of Waste By-Products into Fiber Reinforced M30 Grade of Concrete in Road Pavement

Abstract

According to IRC guidelines, this experimental investigation provides the replacement of waste foundry sand and Construction and demolition waste for mix design of M-30 grade concrete referring IRC44-2017code. Because the minimum concrete grade for country roads is M30, according to IRC-44. As a result, the M30 mix design was picked to begin with. Good concrete quality can only be accomplished by utilizing high-quality ingredient materials, the qualities of which must meet code requirements. To ensure workability, super plasticizer is employed as a chemical additive to concrete in this study. Marsh cone test with a percentage of 0%, 0.25%, 0.5%, 0.75%, 1.0%, 1.25%, 1.5%, 1.75%, and 2.0% to the weight of cement was used to determine the dosage of super plasticizer. Foundry sand has been used to substitute fine aggregate in the proportions of 0 percent, 10.0%, 20.0%, 30.0%, and 40.0% by weight of sand. The coarse aggregate has been substituted by demolition waste in the proportions of 0.0%, 10.0%, 20.0%, 30.0%, and 40.0% by weight of coarse aggregate. A cube of size 150x150x150mm was cast for each trail, and the compressive strength of each cube was measured at required curing period. Result analysis will be used to identify the optimal percentage of replacement of both the replaced materials.
