Influence of slag aggregates on compressive strength of HPC
Abstract eng: Rapidly growing worldwide population is triggering ever increasing demands for housing, industrial sites, civil engineering infrastructure. This is putting an enormous strain on natural resources. When there is a strong need to use industrial by products and minimize cost making it better alternative material. The present study will address the issues associated with the use of blast furnace slag aggregates in place of river aggregates in varying proportions for HPC. The tests were conducted by replacing river aggregates with blast furnace slag aggregates by 0%, 10%, 20%, 30% and 100%. High Performance Concrete (HPC) of M60 grade of concrete was designed as per ACI standards for the present experimental study. The compressive strength tests on cubes were conducted after 28 days. It was observed that compressive strength increased by 7–10% with use of slag aggregate in different combinations. Further, when river aggregates were fully replaced with slag aggregates (100%), then the average increase in compressive strength was 3%.
