Strength Properties of Self Compacting Concrete With Partial Replacement of Cement by Mineral Admixtures Using Polypropylene

Abstract

Self Compacting Concrete has an ability to flow on its own weight hence it can be used where dense reinforcements are present. Self Compacting Concrete can be produced by adding necessary superplasticizers as per the requirement. One of the main reasons of adding mineral admixtures to concrete is to reduce cost. This paper mainly focus on determining the strength characteristics like compressive strength, split tensile strength and flexural strength of SCC where cement is partially replaced by mineral admixtures like GGBS, Fly Ash and Alccofine along with polypropylene. Polypropylene was added to increase the strength slightly and by adding Polypropylene shrinkage values can be reduced considerably and also Microstructure of the concrete samples were also investigated.
