INFLUENCE OF GROUND GRANULATED BLAST FURNACE SLAG ON PROPERTIES OF CONCRETE PAEMENT

Abstract

The influence of using Ground Granulated Blast Furnace Slag (GGBFS) on various properties of Pavement Quality Concrete (PQC) and performance of concrete pavement has been brought out. The amount of GGBFS in PQC mixes was varied from 10 to 60 percent. Workability, compressive strength, flexural strength, abrasion resistance and drying shrinkage of concrete containing GGBFS were evaluated. Significant improvement was observed in strength, abrasion and shrinkage parameters of concrete. The paper concludes that an economical as well as better performing concrete pavement can be constructed by the use of GGBFS in PQC.
