Sbr Latex Admixture: Effects On Sound, Water Absorption And Strength Of Concrete

Abstract

Malaysia is one of the countries that produces the world’s highest of natural rubber latex and since 2001, has become as one of the leading global producers and played a significant role in the rubber industry across Southeast Asia. However, it was found that the demand of natural rubber latex in recent years fluctuated and was affected by the selling price becoming non constant and occasionally the selling price is lower than the investment cost. Therefore, to resolve these issues sustainably, this research was conducted related to applying, using and demanding natural rubber latex in the construction industry materials. Due to that, the study admixture of natural rubber latex in concrete materials was carried out. The aim of this research is to study the effect of applying admixture of natural rubber latex of 15%, 20% and 25% in standard concrete mixture - Grade 20, for the effect of sound absorption, waterproof absorption and compression tensile strength quality. The result shows, more percentage of latex admixtures means the better for soundproof absorption. Furthermore, the more percentage admixture of latex means the less water absorption arose. Lastly, concrete with admixture of 15% latex is the highest compression strength tensile compared with standard and other percentage of latex admixtures.
