Partial Replacement of Cement by Ggbs and Fine Aggregate by Crusher Dust

Due to rapid development in infrastructure it turns out to be very necessary to find and adopt some eco-friendly products. It is becoming more and more obvious that gradual evolution in the field of construction has adverse effect on the well-being the earth and putting future generations in danger. Concrete could also be used for a few special purpose that special properties are more important than those commonly considered. The most important objective of this study is to assess the chances of usage of GGBS (Ground Granulated Blast Furnace Slag) in concrete. The enhancement in a technology requires studying effects caused by the mineral admixture on the strength of the cementitious materials. This project represents the results of an experimental investigations accomplish to understand the suitability of GGBS in production of concrete. In this experimental study the impact of GGBS on strength of referral concrete M20 was prepared using 43 Grade OPC and the other mixes were prepared by replacing part of OPC with GGBS. The replacement levels were 0%, 20%, 30% & 40%(by weight of cement) for GGBS. And replacing fine aggregate with 0%, 20%, 30% & 40% crusher dust
