Abstract
Concrete is a mixture of cement, sand, gravel and water which dries hard and strong and is used as a material for building. Concrete has to be heavily vibrated for flow into very intricate forms or forms that have a lot of reinforcing bars. Hence to overcome these defects the self-compacting concrete is used. Self-compacting concrete is a flowing concrete mixture that is able to consolidate under its own weight. The self-compacting concrete flows easily at suitable speed into formwork without blocking through the reinforcement without being heavily vibrated. This project deals with the self- compacting concrete where the cement is partially replaced with fly-ash and silica fume. Similarly, there is increase in the fresh properties (workability) and decrease in the hardened properties (split-tensile strength and compressive strength) for replacement of fly ash. Self-compacting concrete (SCC) is a type of concrete that can flow under its own weight and completely fill the form work, without vibration effect, and at the same time cohesive enough to be handled without bleeding. SCC usually requires a large content of binder and chemical admixtures. This work outlines the preliminary results of a research project aimed at producing and comparing SCCs incorporating Fly ash (FA) and Rice husk ash (RHA)as supplementary cementing materials in terms of their properties like compressive strength, split tensile strength and flexural strength

Keywords- SCC and Fresh concrete flow, Self-compacting concrete, Fly ash, Rice husk ash, Compressive strength, Flexural strength, Split tensile strength
