Comparatively Study of Compressive Strength of Self-Compacting Concrete with Different Concrete Grade

Abstract

In SCC, also called self-compacting concrete (SCC), voids are filled by its own weight, which prevents vibration. Large office building construction in Japan can significantly reduce noise levels on construction sites and associated environmental effects by implementing the use of SCC. According to the method, gravel makes up 50% of the concrete mix's packed density, while sand makes up 50% of mortar's packed density. Because gravel and sand are considered independently, SCC has a relatively high paste content. Thus, many SCC mixes are stronger than they should be. Recently, there has been a greater acceptance of the use of SCC. Concrete is a crucial and often utilised building material, hence attempts must be made to make it better by, for instance, constructing structures with enhanced mechanical and durability properties. The behaviour of concrete’s compressive strength and its splitting tensile strength is correlated. Analysis and experimental testing of self-compacting concrete (SCC) from different concrete classes were conducted. It was expected that both types of concrete would reach their desired compressive strengths of 25 N/mm2, 30 N/mm2, and 35 N/mm2 at 7, 14, and 28 days. Concrete sample measuring 150 mm in cube shape had their compressive and splitting tensile properties evaluated at 7, 14- and 28-days using compression testing apparatus.
