Developing Sustainable Pavement Concrete By Using Polymer Additives

Abstract

Polymer additives are key components that can significantly modify the properties of concrete. The present study seeks to fill the informational voids concerning the specific enhancing techniques for pavement applications utilizing polymer and SBR additive properties. The mechanical properties of cement incorporating 0 to 2.0% (by mass) polyvinyl alcohol (PVA) and 0 to 30% Styrene-Butadiene Rubber (SBR) were investigated experimentally. The present investigation indicated that the slump test findings imply that the addition of PVA to normal concrete elevates its slump value by under 1%. Nonetheless, an increment over 1% leads to a decline. The ideal workability of the control mix was demonstrated by a droop value of 148 mm after the incorporation of SBR. The combination of PVA and SBR yields a 92.5% increase in collapse. The ideal mechanical characteristics of the concrete compositions are consistently attained by integrating 1% PVA. The findings indicated that the mechanical properties enhanced with 30% SBR, albeit they did not reach the level of PVA. Diverse reactions are noted in the correlation between density and water absorption of the hybrid concrete that integrates PVA and SBR. The concrete's low density will diminish water absorption. The use of PVA and SBR can enhance the strength of concrete by as much as 51.8%.
