Abstract: 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. The results indicated that the replacement of fine aggregate by 20% had attained a good strength in the two mentioned above.
Keywords: Sabbath stone, Silica fume, slump test, Compressive strength, Flexural strength . 1. INTRODUCTION Concrete is a mixture of cement, aggregate and water. The most commonly used fine aggregate is sand derived from river banks. The high consumption of raw materials by the construction sector, results in chronic shortage of building materials and the associated environmental damage. In the last decade, construction industry has been conducted various researches on the utilization of waste products in concrete in order to reduce the utilization of natural resources. In this content, fine aggregate has been replaced by Sabbath( a variety of cuddapah) stone. Crushed Sabbath stone aggregate are more suitable for production of high strength concrete compared to natural gravel and sand. It should be passed through I. S. Sieve 2.36 mm. It should have the fineness modulus 2.50 to 3.50 and silt contents should not be more than 4%. And the admixture of silica fume is a byproduct of producing silica metal or ferrosilicon alloys. One of the most beneficial uses for silica fume is in concrete. Because of its chemical and physical properties, it is a very reactive pozzolanic. Concrete containing silica fume can have very high strength and can be very durable. It is the reliable replacement for river sand in Sabbath stone, Impact environment impact and also its availability of sand properties. By using Sabbath stone and mixing with different type’s ratio and percentage of Sabbath stone, the comparison of it results and analysis can be made whether it is suitable for construction material. It is great practice significance to developing new product for civil engineering works. River sand is one of the principal components of concrete. The cost of river sand is increasing due to the high demand on the construction industry. The selection of ratio must be alone properly by considering the result of the quality of concrete. The source of material added and proportion of the material according to IS 10262-1984 The primary objective of this investigation is to make use of waste Sabbath stone as fine aggregate in concrete. Compression test were performed on waste Sabbath stone concretes by replacing 10%, 20%, & 30% of fine aggregate of waste Sabbath stone and test results were compared. In project work ratio concrete is 1:1.67:2.60 both conventional and replaced concrete of 3 different proportions considered. The testing of this study is based on the sources of material added and proportion of the material according to Indian standard 10262-1984. Test method for compressive strength of brick is based on IS 516.
2. LITERATURE REVIEW The literature review presents the current state of knowledge and examples of successful uses of alternative materials in concrete technology, particularly in use of Sabbath stone as a replacement of fine aggregate.
