Effect of partial replacement of cement with alkali activated Ceramic Waste Powder

Abstract

Ceramic waste powder (CWP) is a remnant of the ceramic industry that is utilized in a variety of industries, including construction, agriculture, glass, and paper, due to its resistance to biological, chemical, and physical forces as a Pozzolanic material. In this research, CWP is combined with an alkali activating solution to partially supplant cement in concrete. The primary objective of using alkali activating solution is to increase the CWP's reactivity. This investigation employs a fluid binder ratio of 0.45, which is typically between 0.40 and 0.60 (IS: 456–2000). A study is conducted to evaluate the strengths of hardened M30 grade concrete with partial replacement of cement of 0%, 10%s, 20%s, 30%s, 40%s, and 50%s with CWP at ages of 7 days and 28 days for constant fluid binder ratio and normal curing. Cubes, cylinders, and beam specimens are cast, cured, and evaluated to determine the effect of replacing cement with CWP. In accordance with the experimental findings, the compressive strength, modulus of elasticity andsplit tensile strengthof concrete containing CWP as a replacement for cement decrease linearly with percentage increase inCWP.
