Rheological properties of self compacting concrete with partial replacement of metakaolin in cement and plastic fibre

Abstract

This work deals with the experimental study of SCC with plastic fibre and metakaolin. Metakaolin with 20% replacement for cement and also addition of plastic fibre in SCC are tested. The influence of mineral admixture and the addition of plastic fibre in physical and mechanical properties in SCC are investigated. Plastic fibre is added to SCC with five various ratio are 0%, 0.25%, 0.5%, 0.75% and 1%respectively. The fresh concrete is tested by L – box test, V – funnel test and U – box test. The hardened concrete is tested by compressive test, flexural strength test and split tensile test. The properties of fresh concrete demonstrated that filling and passing capability of SCC are weak because of introduction of plastic fibre but are not greatly affected the properties. The hardened concrete properties show that metakaolin and plastic fibre has an impact on the strength of SCC.
