Comparison of Rubber as Aggregate and Rubber as Filler in Concrete

Abstract

This research will attempt to use rubber waste (tire rubber) replacement of coarse aggregate to produce early age concrete. An experiment will carry out to determine the strength of early age concrete with rubber waste coarse aggregate to compare with the rubber waste as filler in concrete (with crushed stone coarse aggregate and sand fine aggregate).This research will carry out 2 difference type of concrete which are rubberized concrete and rubber filler in concrete. In rubberized concrete, rubbers were used to replace coarse aggregates and river sand as fine aggregate. Furthermore, in rubber filler in concrete, crushed stone was used as coarse aggregate and river sand as fine aggregate. Coarse aggregate usually gravel or crushed stone and shredded rubber as filler in concrete. The design strength of mixture concrete is 15 MPa for 7 days and water cement ratio are 0.4, 0.5, and 0.7. Lastly; the compression cube test will be test on 7 days. The properties of the aggregate will compared.
