Experimental Investigation of Self-Compacting Concrete Using Coir Fiber

Abstract

Concrete is the construction material widely used throughout the world. Construction materials used in the industry should be friendly with the environment during their usage. Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogenous and has the same engineering properties and durability as traditional vibrated concrete. In order to obtain the properties of hardened concrete for SCC, proportion of mineral and chemical admixtures to be added. Since it was first developed in Japan in 1988, SCC has gained wider acceptance in Japan, Europe and USA due to its inherent distinct advantages. The contributing factors to this reluctance appear to be lack of any supportive evidence of its suitability with local aggregates and the harsh environmental conditions. In this study, a review is presented based on the development of self-compacting concrete with mineral admixture-coir fiber. On various percentages of coir fiber, the SCC properties were studied. Coir fiber was added in concrete 0.25, 0.5 and 1% by weight of cement and M-sand and C-sand was replaced by 10,20 and 30% by weight of normal sand.
