Effect of Activated Carbon, CMC and Fly Ash on Different Grade of Concrete

Abstract

Cement is the extensively used material in the world after water. Adding new functional materials to like Activated Carbon (AC), Carboxymethylcellulose (CMC) sodium salt, fly ash (FA), PCE (Poly Carboxylic Ether) based plasticizer can improve the quality and add novel characteristics. Also, reducing the usage of cement. This study focused on the investigation of compressive strength and modulus of elasticity after introduction of CMC, AC, FA on different grade of concrete. 41 batches of concrete were prepared and tested for M 30 and M 25 grade concrete. The AC being a highly hydrophobic material, agglomeration occurs. CMC sodium salt aqueous solution is chosen surfactant to form the gel structure to disperse the AC. Standard mix design of 132 concrete cubes were carried out varying CMC, AC, FA and its effects were analyzed.
