ANALYSIS OF COMPRESSIVE STRENGTH OF CONCRETE PREPARED BY PARTIAL REPLACEMENT OF SAND WITH GBBS AND FLY ASH Dhairya kaushal1, Saurabh Gupta2 1M.tech Student, Department of Civil Engineering, Arni University 2 Assistant Professor, Department of Civil Engineering, Arni University
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract – The experiment was performed to conclude the compressive strength properties of the concrete prepared with
ground Granulated Blast furnace slag (GGBS) and partial replacement of the fly ash by weight with the cement. As the utilization of the cement is increasing day by day so does its production as its ingredient are dependence on the natural resources. So stress on the natural resources is increasing day by day for the production of the cement. Keep that in notice, alternative or partial replacement of the cement is done with fly ash and replacement of aggregate with GBBS is done with an aim to find the optimum level. After going through the literature review, for this experiment we choose M25 grade of concrete and prepared different sample with different percentage up to 20% of GBBS and up to 10% of fly ash. There is also discussion about the slump representing the effect on the workability of the replacements done as mentioned above. Further the result has been discussed. The outcomes of the research indicate that the addition of GGBS and Fly Ash enhanced the workability and compressive strength of the concrete prepared which eventually improved the mechanical properties of concrete.

INTRODUCTION Natural sand is a admixture of small grains of gemstone and grainy accoutrements which is substantially defined by size, being finer than clay and coarser than ground. And ranging in size from0.06 mm to 2 mm. patches which are larger than0.0078125 mm but lower than0.0625 mm are nominated ground. Beach is made by corrosion or broken pebbles and riding of jewels, which is carried by swell or gutters. And indurating and deliquescing during the downtime break gemstone up the beach will be made. occasionally Beach on strands can also be made by small broken-up pieces of coral, bone, and shell, which are broken up by bloodsuckers and also bombarded by the ocean, and indeed bitsy pieces of glass from bottles discarded in the ocean and other mineral accoutrements or the bones of fishes or other oceanic creatures. Beach can be also considered as a textural class of soil or soil type. A flaxen soil containing further than 85 percent beachsized patches by mass. Beach is principally made of loose grainy accoutrements conforming of either gemstone fractions or mineral patches or oceanic accoutrements . It's substantially made of silicate minerals and silicate gemstone grainy patches. generally quartz is the most dominant mineral then as it possesses largely resistant parcels to rainfall. Other common gemstone- forming minerals like amphiboles and micas also set up in beach. Heavy minerals similar as tourmaline, baguette, etc can also be present in the beach in lower attention. But from a high position, utmost beach on the sand is made up of argentine or tan quartz and feldspar. still, the most common mineral in the beach is quartz – also known as silicon dioxide. This is formed when silicon and oxygen combine. Feldspar is the most set up group of minerals on the earth’s face and forms about 65 of the terrestrial jewels. When the wind and ocean scourge over on the props, they transport these teeny- bitsy grains to the sand and make up the beach with this combination
2. MATERIAL The materials used in this work can be broadly classified as base material, filler material and binder. The type of material used is having properties of both inert and reactive materials which were used for this study. The various materials used in this work are discussed with their properties and with the test results as follows. 2.1 Cement: Ordinary Portland cement of 53 grades was used in this study which was provided by Ultratech Cements Ltd. The value of specific gravity of the cement Ordinary Portland Cement of 53 grade is 3.15 as per IS: 12269- 1987. 2.2 Aggregates: There are two types of aggregate being used for the experiment: Fine aggregate and course aggregate. The Fine aggregates used in this research are taken from nearby river tributary of Beas having max size of 4.75mm. Coarse aggregates used are of crushed stone from the nearby crusher such that the stone passing through 20mm IS sieve and retained on 4.75mm IS sieve.
