Effect on Compressive Strength of Concrete by The Use of Metakaolin, Laterite Sand and Quarry Dust

Abstract

When ordinary Portland cement is used in structures bearing huge loads, it requires more quantity of cement to achieve strength. This leads to increase in cross section of structure which increases dead load of structure. Hence in this project, partial amount of cement will be replaced by supplementary cementious material metakaolin to increase the strength of concrete. Also Portland cement production is one of the major reasons for CO2 emissions into atmosphere. It is due to the use of fossil fuels, including the fuels required to generate electricity during cement manufacturing process. Supplementary cementious materials are often used to reduce cement contents. Here metakaolin will be used and increase in compressive strength of concrete will be determined.
