Abstract: The high consumption of raw materials by the construction sector, results in chronic shortage of building materials and the associated environmental damage. Concrete industry is particularly important as it is not only responsible for consuming natural resources and energy but also for its capacity of absorbing other industries waste and by-products. For this reason the civil and environmental engineers have been challenged to convert the industrial waste to useful building and construction materials. In recent years the construction industry has shown considerable interest in the utilization of waste. To create products made of stone, the shape of the stone must be decorated through cutting , shaping and finishing, which can release dust and slurry sludge, in addition to these the waste stone cutting pieces are also generated. The stone pieces are creating disposal problems in and around the production area. At present the stone waste generating in exploration area and polishing industry are dumping in low lying area and in and around the road way. In Andhra Pradesh, Tadipatri is located in Anantapur District Basically this region is much potential for black layered stone. This stones are used in the construction industry for floors. The main aim of research work is to utilize the stone waste in the construction industry. Generally for concrete works crushed granite stone is used as coarse aggregate. In the proposed research work the waste produced by the polishing industries can be replaced in the place of granite and the Mechanical and Thermal properties were measured by heating IS standard cubes and cylinders at 5 °C/min to temperatures of up to 800 °C results are to be studied. The obtained results of mechanical property measurement are compared with results obtained in other studies as well as with existing code provisions to evaluate their applicability. The research work is mainly focused to utilize the waste for the concrete works and later stages it may be recommended to use for the construction industry. The waste may be partially and fully replaced in placed of natural granite.
While these studies provided valuable information on concrete strength as a function of temperatures, almost all used specimens made with normal strength concrete made of granite aggregate. Thus, in light of the results of recent studies, which have shown that concrete behaviour at elevated temperature may be significantly different from that of Normal Strength Concrete. To study the thermal strength properties of concrete produced with stone waste aggregate. The coarse aggregate will be replaced by stone waste aggregate from 0 to 100% The compressive strength and split strength test of the concrete is to be tested under 00, 1000 , 2000 , 4000 , 6000 and 8000 temperatures and conclusions are to be drawn on their performance.
