Experimental Investigation on Partial Replacement of Fine Aggregate with Sabbath (Cudappah Stone)

River sand is most commonly used fine aggregate in concrete but due to acute shortage in many areas, availability cost and environmental impact on the major concern. In developing countries like India Sabbath stone has been rampantly used in different construction purpose. The replacement technology has emerged as an innovative development of civil engineering material design mix of M30 grade of concrete with replacement of 0%, 10%, 20% and 30% of Sabbath stone. For laboratory analysis of Slump test, Compressive strength test, Flexural strength and Water absorption of hardened concrete. A comparison was made between specimen of partially replaced fine aggregate and the same set of specimen admixed with Silica fume. Attempts have been made to study the properties of concrete and to investigate some properties of Sabbath stone the suitability of those properties to enable them to be used as partial replacement materials for fine aggregate in concrete. The results indicated that the replacement of fine aggregate by 20% had attained a good strength in the two mentioned above.
