A Research on study Behaviour of Concrete by Partial Replacement of Cement with Metakaolin and GGBS

Concrete has been used as a major construction material for many decades. With the rapid increase in the infrastructure of our country there is a need to upgrade concrete properties by incorporating various materials in the design mix. Hence a lot of research work is being carried out for this purpose. There is nascent concern in the use of supplementary cementing material as production of binary and ternary concrete matrices. This study presents the effect of incorporating Metakaolin MK and Silica Fumes SF on strength parameter of ternary pavement concrete blending cement CEM with Ground Granulated Blast Furnace Slag GGBS for a constant water binder ratio of 0.33. Twenty two mixtures prepared by replacing of cement with GGBS 20 , 40 , and 60 , SF 10 , 15 , and 20 and MK 10 , 15 , and 20 were designed for target strength 48 Mpa. From the results, it was observed that 45 replacement of cement with GGBS in binary blend concrete Cement GGBS show optimum level in terms of compressive strength at 28 days and also 56 days, beyond the 45 replacement level strength decreases. In ternary blend concrete mix S40MK15 CEM 40 , GGBS 40 andamp MK 15 and S40SF15 CEM 40 , GGBS 40 andamp SF 15 shows the optimum strength. Splitting tensile strength and flexural strength values have also followed the same trend. Finally this study concludes that the ternary concrete blends cement with 40 GGBS and 15 MK show the desired properties which is almost equal as compared to the ternary concrete blends cement with 40 GGBS and 15 SF. Hence both of these mixes can be used economically depending upon their availability.
