Compressive Strength, Water Absorption and Temperature Effects on Partial Replacing Cement with GGBS, Micro Silica and Fly Ash

Abstract

Widespread research work for decades also in development throughout the globe in concrete technology in finding substitute materials which can incompletely change Pozzolonic Portland Cement (PPC) and which can also meet the necessities of the strength and durability performance of industrial by products like micro silica, ground granulated blast furnace slag, fly ash, etc. now termed as complimentary cementations materials (CCM) are quite promising. The increased quest for sustainable and eco-friendly materials in the construction industry has led to the research on partial replacement of the conventional constituents of concrete by the three selected waste materials. The broad aim of this work is to investigate the effects of partially replaced Pozzolonic Portland Cement (PPC) by Ground Granulated Blast Furnace Slag (GGBS), fly ash and micro silica on the properties of concrete. The prepared mix is the one with (10%, 20%, and 30%) GGBS, fly ash, micro silica is replaced to cement in M30 grade. Experimental investigations like compressive strength at 7, 14, 28 days are tested, water absorption and thermal effect are tested at 28 days. Thus, the micro silica can potentially be used as a cement replacement material for structural concrete applications.
