Experimental Study on the Strength Characteristics of M25 & M30 Grades of Self-Compaction Concrete by Partial Replacement of Saw Dust in Fine Aggregates

Abstract

Abstract: Self - compacting concrete (SCC) is a high - execution concrete that can stream under its own load to totally fill the structure work and self-unites with next to no mechanical vibration. Such concretes are a speed up for the placement, to lessen the work prerequisites required for combination, getting done and wipe out ecological contamination. This will guarantee that the concrete acquired has great stream capacity, self-compacting capacity and other wanted SCC properties.Self-compacting concrete is a kind of concrete that gets under its self-weight. Self-compacting concrete is a type of concrete that gets under its self-weight. It is commonly abbreviated as the concrete. Which can placed and compacted in to every corner of a formwork; purely means of its self-weight by eliminating the need of either external energy input from vibrators or any type of compacting effort. There is a current trend in all over the world to utilize the treated and untreated industrial By-products, domestic wastes etc. as raw materials in concrete. These not only help in the reduce of the waste materials but also create a cleaner and greener environment. This report demonstrates the possibilities of using saw dust as partial replacement of fine aggregate in concrete. This experimental investigation was performed to evaluate the strength and durability properties of M25 and M30 grade of self compaction concrete, in which fine aggregate was partial, replaced with saw dust waste. Fine aggregate was replaced with four percentage (0%, 10%, 20%, 30%) of saw dust waste by weight. Fresh properties of self-compacting concrete were studied. Compression test and splitting tensile strength test were carried out to evaluate the strength properties of concrete at the age of 7, 14, and 28 days.
