Partial replacement of Sand by scrap rubber tyre impact on concrete paver block

Abstract

With the growth and development on all fronts all country, economic and infrastructural there is an increasing need for new facilities, building, roads etc. This has in turn resulted in a huge demand for the material of construction and the raw materials from which these are obtained or made, thus putting an increasing pressure on the natural environment around us. The consumption of waste material can be increase manifold if these are used as fine aggregate into concrete. This type of use of waste material can solve problems of lack of aggregate in various construction sites and also reduce sort of concrete production.The M₂₀ grade concrete has been chosen as the reference concrete specimen. Scrap tire rubber, in size less than 4.75mm and greater than 75µ has been used as fine aggregate with the replacement of conventional fine aggregate in concrete paver. A series of Compressive strength test will be carried out on rubberized concrete paver block with a different percentage and also verify the density of rubberized concrete paver block. The feasibility of replacing fine tire rubber in concrete is concluded for improving the compressive strength of traditional concrete.
