Based on the global usage, concrete is placed exponential growth rate of population from last few at second position over water. It plays a very decades the basic strategies to decrease solid waste significant role in the shaping our environment and disposal problems have been focused at the sustainability of the construction industry. Ever reduction of waste production and recovery of since its discovery has become indispensable in usable materials from the waste as raw materials as construction practices, owing to its durable, reliable well as utilization of waste as raw materials and workable properties. The name concrete is whenever possible. Natural aggregate is becoming derived from the Latin term “concretes” meaning expensive due to scarcity. The world-wide ‘grows together’ hinting at the chemical hydration consumption of natural aggregate as coarse process that causes the material inside to grow aggregate in concrete production is very high and together from a visco-elastic state into a hard, dense several developing countries have encouraged some and durable product. There are numerous plans of demand in the supply of natural aggregate in order solid, which give differing properties, and cement is to meet the increasing needs of infrastructural the most-utilized man-made item on the planet. development in recent years. In particular, the Meanwhile we are not allowed to complete the demand of natural aggregate is quite high in natural resource usage in concrete. We have some developing countries owing to rapid infrastructural waste materials which were not useful in that pattern growth. of works. In the recent years, the growth in industrial One of those materials is Bethamcherla marble stone production and the consequent increase in aggregates as replacement of coarse aggregate in consumption have lead to fast decline in available concrete. This paper represents the study of natural resources on the other hand, a high volume regression analysis of compression and tension of of production has generated a considerable amount concrete for different combinations. The comparison of course material which have adverse impact on the is made between conventional aggregate cubes and environment. The Civil Engineering construction cylinders made with Bethamcherla marble stone industry is to be one of the most potential consumers aggregates (BMSA). The cubes and cylinders of of mineral recourses, thus generating a great amount varying proportions are casted replacing partially of solid waste as a bye product stones. Stones have and totally natural granite coarse aggregate (NGCA) perhaps the noblest material from nature used by with using BMSA. The cubes and cylinders are men for his artistic expression. In the concrete tested by adding GI steel fibre of volume 0%, 1% industry, generally used coarse aggregate is obtained and 2% of volume of conventional cube. It is from granite rocks, but in locations where there is no observed that there is consistent decrease of availability of granite rocks and also in the places compressive strength of concrete of 0, 25, 50, 75 and where, there is a disposal problem of Bethamcherla 100 % of replacement of natural granite coarse marble waste, in such situations, the usage of BMSA aggregate (NGCA) with Bethamcherla marble stone is an advantageous consideration. aggregates. It was also observed that strength Bethamcherla marble is abundantly available, increased (volume) when 1% and 2% of GI steel occupying about 10% of the earth’s surface in fibers were used compared with conventional cube different forms.

INTRODUCTION Bethamcherla limestone from the town of Bethamcherla, located in the Kurnool district of The global use of concrete is next to water in this Andhra Pradesh is considered. This occurs in the era. As the demand for concrete as construction naturally cleft slab like elements which on polishing Volume 7, Issue 11, 2018 Page No: 108 International Journal of Scientific Research and Review ISSN NO: 2279-543X and processing into regular shapes that would make The stone itself, specifically in the forms of an excellent strength of flooring stone that has the overburden, screening residual, stone fragments. luster and finish on par with its granite counterpart. Stone wastes are generated as a waste during the Bethamcherla waste stone is one of the natural process of cutting and polishing. It is estimated that mineral having specific gravity ranging from 2.6 to 175 million tons of quarrying waste are produced 2.85. Bethamcherla marble stones are fundamental each year, and although a portion of this waste may flaggy lime stone with natural split. It is very be utilized on-site, such as for excavation pit refill or excellent flooring stone, which have been unique berm construction, the disposals of these waste geo mechanical properties required for flooring materials acquire large land areas and remain stones. scattered all around, spoiling the aesthetic of the entire region. In this project we crushed BMSA into AIM AND SCOPE OF THE STUDY required sizes i.e., 20mm . Main aim of the study is to know the involvement of Fine aggregate: Bethamcherla waste stone in construction works. In The amount of fine aggregate usage is very this study importantly, it is concentrated on some important in concrete. This will help in filling the basic properties Bethamcherla waste stone, to know voids present between coarse aggregate and they the suitability of the Bethamcherla waste stone in mix with cementitous materials and form a paste to construction works by conducting some workability coat aggregate particles and that affect the compact tests and some mechanical properties tests, in this ability of the mix. The aggregates used in this paper we worked with regression analysis of research are without impurities like clay, shale and compression and tension strength. To make explore organic matters. It is passing through 4.75mm sieve. the usage of local accessible materials to the surrounding people. IV EXPERIMENTAL INVESTIGATION II.
