Experimental Investigation on Self Compacting Concrete by Partially Replacing Crushed Quartzite as Fine Aggregate

Self-Compacting Concrete (SCC) is one of the modern techniques in the concrete research. The SCC is able to flow and fill the most restacked places to the form work without vibration. For SCC, super plasticizer is used in order to improve high mobility. There are several methods for testing SCC properties in fresh state the most frequently used tests are slump flow test, L-box, V funnel test. In recent days the demand for river sand is increasing due to lesser availability. In India the conventional concrete is produced using natural sand obtained from river beds as fine aggregate. Decreasing natural resources poses the environmental problem and hence State Government restrictions on sand quarrying result in scarcity and significant increase in its cost. This project presents the properties of SCC, mixed with quartzite as fine aggregate. This project aims to focus on the possibility of using industrial by-product like crushed quartzite. The usage of this crushed quartzite is proposed as partial replacement of fine aggregate in the production of SCC. Strengths properties such as Compressive strength, Tensile strength, Split Tensile Strength of SCC is determined at the age of 28 days with normal curing.
