Performance of Concrete Containing Fine Recycled Concrete Aggregate (FRCA) and Fine Crumb Rubber (FCR) As Partial Sand Replacement

Abstract

Natural fine aggregate materials are frequently used in development and commercial construction in Malaysia. In fact, concrete production was increased as linear with the growing Malaysia economy. However, an issue of concrete production was to locate adequate sources of natural fine aggregates. There lot of studies have been conducted in order to replace the fine aggregate in which natural fine aggregate replace with the waste material in concrete preparation. Therefore, this study will promote usage of fine recycled concrete aggregate (FRCA) and fine crumb rubber (FCR) as suitable materials to be used in the construction industry as partial sand replacement materials. It helps to protect the natural environment from the disposal of wastes and also reduce construction cost by using industrial waste. Until today, none of researchers have done studies for the effect of combination of FRCA and FCR as partial sand replacement materials towards the strength properties of concrete. Therefore, this research will study the strength properties of concrete containing combination of FRCA and FCR as partial sand replacement materials. The design replacement of FRCA which is 0%, 15%, 30%, 45% and 60% and CR of 0%, 1.5%, 3%, 4.5% and 6% will be evaluate. Other than that, 0.5 water cement ratio will be used in this research. This study involved is workability, density, compressive strength, tensile strength and water absorption tests.
