Abstract – The utilization of supplementary cementation materials is well accepted, since it leads to several possible improvements in the concrete composites, as well as the overall economy. The present paper is an effort to quantify the strength of ground granulated blast furnace slag (GGBS) at various replacement levels and evaluate its efficiencies in concrete. Cement with GGBS replacement has emerged as a major alternative to conventional concrete and has rapidly drawn the concrete industry attention due to its cement savings, energy savings, cost savings, environmental and socio-economic benefits. The use of fine materials such as crushed rock powder as a replacement for fine aggregate enhances the property of concrete. Since, concrete is weak in tension hybrid fibers such as asbestos fiber are used to improve the tensile property of the concrete structures. The initial results of experimental programs aimed at producing and evaluating SCC made with GGBFS, crushed rock powder and hybrid fibers are presented and discussed. This research evaluates the strength and strength efficiency factors of hardened concrete, by partially replacing cement by ground granulated blast furnace slag for M30 grade of concrete at a percentage of ( 5-20%) and fine aggregate by crushed rock powder at varying percentage of (30-40). Asbestos fibers were used to increase the tensile strength of concrete.
