Adding granulated crumb rubber from recycled scrap tires in concrete as apartial replacement to fine aggregate in the creation of Rubbercrete has givennumerous advantages to not only the environment, but also as its usage of theconcrete itself. Numerous properties of Rubbercrete are enhanced compared toconventional concrete when crumb rubber is partially replaced with fine aggregate.Nevertheless, there are notable drawbacks to the usage of Rubbercrete which includesthe reduction in strength of the Rubbercrete which will eventually limit the use ofRubbercrete in the construction industry. Along these lines, this progress report willshow techniques on manufacturing Rubbercrete on which its compressive strengthcan be compared to that of conventional concrete, where this said technique includesthe adding of Nano silica into the concrete design mix. Approximately 30 designmixes were designed with usage of Response Surface Methodology (RSM) at threelevels of crumb rubber replacement by volume to fine aggregate (0, 15, 30),three levels of Nano silica addition (0, 2.5, 5) and three levels of Fly ashaddition (0, 35, 70). Subsequently, six more design mixes were created by theRSM to determine the most optimum design mix from the initial 30 design mixes.These six optimized design mixes are then required for experimental testing(shrinkage test, modulus of elasticity and Poisson's Ratio test) to determine thedeformation properties of Rubbercrete. Ultimately, it is to be concluded that theaddition of Nano silica would refine the extent of the pores and densify the InterfacialTransition Zone (ITZ) between the surface matrix of the aggregates and cement in thesolidifying of Rubbercrete. Eventually, the Rubbercrete will obtain a slightly if not,much better compressive strength compared to conventional concrete. © IAEME Publication.
