In the present study, an investigation is done to find out the strength properties of concrete by partialreplacement of cement with Metakaolin (MK) and Fine Aggregate with Quarry Dust(QD). Metakaolin is a substanceobtained from calcination(heat treatment) of Kaolin (clay mineral) at a temperature of 650-800 0C.It has good pozzolonicproperties and is used as a replacement of cement. The other substance used in this study is Quarry Dust which is obtainedfrom crushing of stones during quarrying activities. Hence Natural Sand is being replaced with Quarry Dust. Thereplacement percentages of Metakaolin with Cement are 0%,10%,15% and 20% .25%,50%,75% and 100% of Quarry Dustare adopted as a replacement of Fine Aggregate. The effect of Quarry Dust with varying percentages of Metakaolin onstrength properties of M25 Grade of concrete is studied. The tests performed are Compressive Strength test, Split TensileStrength, Flexural Strength and Modulus of Elasticity. All the test results are compared with Controlled concrete. From theresults it is known that the optimum replacement percentages of Metakaolin (MK) and Quarry Dust (MS) are 15% and 50%respectively. At a combination of 15% Metakaolin and 50% Quarry Dust, the results of all the tests performed has shown theoptimum value.
