EXPERIMENTAL STUDY ON RUBBERISED CONCRETE

Abstract

Solid waste management is one most important environmental concern worldwide. Concrete
is third most important resource used by humans after air and water. The most commonly used coarse
aggregate is crushed rock ballast. The manufacture of coarse aggregate by crushing rock ballast causes
environmental pollution. Now a day there is a scarcity of coarse aggregate due to increase in cost and
infrastructural growth. This mainly directed towards exploring the possibilities of making effective use of
alternative materials. In many research tyre rubber is used to replace course aggregate. The present study
is to produce rubberized concrete by partial replacement of course aggregate. The purpose of this study is
to see the behavior of concrete with different proportion of scrap tyre rubber. For that concrete mixed with
scrap rubber on different proportion of course aggregate and, compressive strength for
7days ,14days,28days and other mechanical properties measured. It has been observed from the previous
research data that the overall strength concrete decreases as per the rubber particles increases when
compared to ordinary concrete . Rubberized concrete mixes may be suitable for structural and
nonstructural purposes such as lightweight concrete walls, building facades and architectural units. The
crumb rubber with concrete will find new areas of usage in highway construction as a shock absorber, in
sound barriers as a sound absorber, and also in buildings as an earthquake shock-wave absorber.
