Experimental Study to Improve the Durability of Self Compacting Concrete Using Waste Marble Dust and Fly Ash

Abstract

This paper investigates the study of workability and durability characteristics of Self-Compacting Concrete
(SCC) with waste marble dust and containing Class F fly ash. The process of the development of the concrete for
durability aspects in various proportions varying from 0%, 10%, 15%, 20% and 25% marble dust as a replacement of
cement along with fly ash. The main aim of the investigation was to identify the best proportion of marble dust with fly
ash, which can be replaced with cement to get the desired durability. The proportion of fly ash was taken as 30% by
weight of cement decided from previous studies published in various Studies. The effect of marble dust is evaluated by
performing the different tests on the cubes and cylinders to know its durability, durability tests (compressive strength of
cubes after cured in sodium chloride and sulphuric acid for 56 days). Tests of these specimens were conducted at 7, 28
and 56 days after casting.
