Experimental Investigation on Self Compacting Concrete by Partial Replacement of Coarse Aggregate with Air Cooled Blast Furnace Slag

Concrete can be considered as the most widely used in the construction industry. Concrete is a composite material made up of cement, sand, water and sometimes admixtures. Cement is the most active component and the use of large quantities of cement results in increasing CO2 emissions and as a consequence of the greenhouse effect. On the other hand continuous use of natural aggregates causes environmental problems and it is also necessary to preserve the natural sources. The use of sustainable technologies such as supplementary materials is expected to positively affect the performance of concrete mixtures. Self-compacting concrete (SCC) is an innovative development of conventional concrete, which can be placed and compacted under its self-weight with little or no vibration effort. This paper present the Mechanical properties of self-compacting concrete using cementitious materials as a partial replacement of Artificial aggregate as natural aggregate having fineness modulus 2.7; Coarse aggregate of size 12mm. SCC containing different proportion of these mineral admixtures has been tested for slump flow, V-funnel, L-box, U-box and J-ring and found that the values are within the limits prescribed by EFNARC, 2002 method. The properties reported in this paper are the workability properties, Mechanical properties and Durability Properties. The Workability properties were investigated by Slump flow (filling ability), V-Funnel (filling ability) and L-Box test (passing ability). The Mechanical properties were tested for Compressive strength, Splitting Tensile strength and Flexural strength of 14 days, 28 days and 56 days were obtained.
