“STUDY ON STRENGTH OF CONCRETE BY PARTIALLY REPLACEMENT OF CEMENT WITH METAKAOLIN, CALCIUM CARBIDE RESIDUE (CCR) AND FLY ASH" Qudsiya Sabreen, Ms. Shweta Chouhan 1 Qudsiya Sabreen , M.tech Scholar Maharishi Arvind International institute of technology, kota (Rajasthan) Ms Shweta Chouhan, Assitant Professor Maharishi Arvind International institute of technology, kota (Rajasthan) ---------------------------------------------------------------------***---------------------------------------------------------------------
Abstract - In the present work it has been explored to use
the blended mix of Meta kaolin, Calcium Carbide Residue and Fly Ash by partial replacement of cement with appropriate % in concrete to develop concrete. Present study evaluates strength and durability parameters of the concrete containing the combination of above-mentioned materials. For durability analysis 5 % H2SO4 and 5 % HCL solutions prepared and sample were immersed in acid solution for 28 days, then % change loss in compressive strength with reference to control mix was observed. The experimental program consists of preparing concrete mixes with Meta kaolin as a partial replacement of cement (5%, 10% and15%) and similarly CCR and Fly ash also used as a partial replacement Cement with the same proportions. The performance of the concrete mixes for compressive strength at 7 days and 28 days, compressive strength after 28 days acid curing test were investigated.
Saurav and Ashok Kumar Gupta (2014) have investigated on experimental study of strength relationship of concrete cube and concrete cylinder using ultrafine slag (Ground granulated blast-furnace slag) and have shown the comparison between cubical strength and cylindrical strength of normal concrete and with partial replacement of cement with ultra fine slag (Ground-granulated blast-furnace slag) and varies at 3%, 5%, 7%, 10%, 13%, 15% & 18.
The main aim of this study is to investigate combined use of Meta kaolin, Calcium carbide residue and fly ash in concrete by partial replacement of cement. Grade of concrete for the study has been chosen as M 30, as it offers good number of applications in the construction industry, ranging from pavement to buildings. Initially the study is done on the individual effects for all materials on concrete by replacing cement and then searching the optimum percentage replacement level for Meta kaolin, Calcium carbide residue and fly ash to investigate the combined effect of these replacing materials on blended concrete.
The following conclusion are reported –
Mechanical properties of concrete increased by 10% comparative to control mix with 30% steel slag.
Compressive and tensile strength increased with the addition of above mentioned replacing materials.
Rahul et. Al. (2015) have investigated on fresh and hardened properties of M-20 grade concrete with fly ash and steel fibres. Fly ash was used as a partial replacement of cement (5%, 10%, 15%, 20%, 25% by cement weight) with the addition of 0.5%, 1%, 1.5%, 2% by weight of cement and following conclusions are made on different strength parameters –
1.1 Literature Review Karthiga et all (2018) have investigated the strength parameters for M35 grade of concrete. The experimental study is basically a combination of GGBS and CCR replacement by cement and got the test results for 28 days and following conclusions were made –
With the addition of fly ash from 5 to 25 percent there was a reduction of compressive strength at the age of 28 days.
Workability of mix increased with the fly ash.
15% CCR and 20% GGBS combination provide better results, almost equal to the control mix.

It was observed that higher compressive cube strength over compressive cylinder strength at 13% replacement of cement with ultra fine slag (GGBS) attained.
Aiswarya and Navaneetha (2016) have investigated the compressive strength, split tensile strength and flexural strength for the M 30 grade of concrete. In this study it used fly ash as partial replacement of cement and the replacement level was 5,10 and 15 percent. Similarly fine aggregated replaced by steel slag 30% and also add 1% glass fiber, then above mentioned test carried out for 7 and 28 days.
1. INTRODUCTION
With the higher replacement ratio of CCR in the mix , resulting decrease in strength.
