Abstract

The project is intended to develop cost effective of Self- compacting Concrete (SCC) .Nowadays, the construction industry in Malaysia as well as in all over the world is looking for more economical construction materials. In addition, the existing of self-compacting concrete is facing brittleness problem due to their high binder (powder) content and low aggregate amount. Hence, the aim objective of this research is to investigate the effect of different fibers on properties of self-compacting concrete. The aim is supported by two sub-objectives which are to compose the effect of Copped Basalt Fiber (CBF) and Polyvinyl Alcohol Fiber (PVA) with addition of Fly ash (FA) as the filler material on compressive and tensile strength, and to investigate and compare the effect of PVA, CBF on the workability characteristic of SCC. This study can satisfy the requirements of construction standards of self-compacting concrete found in both European Federation of National Associations Representing for Concrete (EFNARC) and Japan Society of Civil Engineers (JSCE). To achieve the research objectives there are different concrete mix has been prepared in UTP concrete laboratory. Experimental work consists of 90 cubes of size 100mm3, 10 cylinders of size 100 x 200 mm2, and 10 beams of 100 x 100 x 500 mm3. The compressive strength was tested for 7days, 28days, and 56days while the splitting tensile and flexural strengths were cast only for 28-days. The concrete mix used in this experimental study formed into two groups of concrete mix. The firs group consists of 100% OPC, while the second group consists of 70% OPC and 30% Fly ash. In each of the above groups different percentage of fibers i.e. 1% and 2% was added and the characteristics of fresh and hardened concrete were investigated. The research project showed that the fibers have slight effect of the fresh properties as well as hardened properties of self-compacting concrete mix (SCC).
