DURABILITY STUDIES ON COMPOSITE FIBRE REINFORCED SELF COMPACTING CONCRETE USING ECO FRIENDLY BY PRODUCT INDUSTRIAL MATERIALS

B. Sugumaran, Prince G. Arulraj and R. Anuradha

Abstract

Concrete is an important material used in the construction industries. Fibre reinforced Self compacting concrete (FRSCC) is a special type of concrete used in specific construction practices. The durability aspect of FRSCC is a thrust area which is to be concentrated. In addition production of cement liberates excess CO2 to the atmosphere. Utilization of river sand for concrete also causes depletion to the environment. Suitable material can be used as admixture to improve the quality of FRSCC as well to minimize the ill-effects caused to the environment. In this study, Ground granulated blast furnace slag(GGBS) is identified as partial replacing material with the cement and complete river sand is replaced with manufactured sand (M-sand) which is a remains from dressing of stones. A total of 16 FRSCC mixes including conventional mixes were investigated in this study. To assess the durability properties acid attack and chloride attack tests were performed. In addition, shrinkage studies are also carried out. In general, all single type of fibre impregnation caused an increase in the compressive strength when subjected to chemical attacks. However, the contributing effects of composite fibres have shown improvement of compressive strength than conventional and single fibre concrete mixes. Composite fibres showed better performance than the single fibres in shrinkage aspect also.
