Properties of SCC with marble powder as a marginal material

Abstract

Concrete is one of the most vital materials in construction. In recent past self-compacting concrete has been emerged as a major innovation in the construction field which doesn’t require any external compaction. Most of the materials used in this concrete are from natural resources, to fulfill the requirement of materials quantity, the major concern to the environment caused is depletion of these resources. In order to overcome this issue, many researchers have used supplementary materials like marble powder, glass dust, quarry dust etc., as a partial replacement for Fine Aggregate. This paper reports on the properties of self-compacting concrete of M35 grade made by using marginal materials fly ash and marble powder as partial replacement for cement and fine aggregate respectively. The fly ash is used as replacement for cement at an optimum percentage of 25% and sand is replaced by marble powder at varying percentages from 0% to 30% increments of 10%. Tests were conducted on the mixes to evaluate workability and mechanical properties of concrete in fresh and hardened state and to assess durability property, acid attack test was conducted. Results were found satisfactory at 20% replacement of sand with marble powder.
