Investigating the performance of self-compacting concrete pavement containing GGBS

Abstract

The present experimental investigation focused on the effect of Ground granulated blast furnace slag (GGBS) on Self-Compacting Concrete (SCC) Pavement. Generally, the pavement requirements are workability, mechanical strength, drying shrinkage, and abrasion resistance, and these are predicted in the present experimental investigation as a function of GGBS percentage. The GGBS of 0% to 60% is partially replaced with cement to accomplish the maximal performance of SCC. From the experimental investigation, the workability properties are improved as the percentage of GGBS enhances. Mechanical strength properties like compressive, flexural, and split tensile strength of SCC mixes are improved till 40% if GGBS is introduced in place of cement. It is identified that the percentage of GGBS increases when the drying shrinkage of concrete reduces. For abrasion resistance, the percentage of weight loss is minimal for SCC mixtures as the percentage of GGBS increases. Relationships are established between slump flow (mm) and T50cm (sec), similarly the dependence of flexural strength on compressive strength of SCC mixtures are reported for further development of concrete pavements.
