Effect of Styrene Butadiene Ratio on Mechanical Properties of Concrete Mixture

摘要

Experiments were carried out to study the mechanical properties of concrete modified by Carboxylated styrene-butadiene rubber (X-SBR) polymer, using mortar samples with various styrene butadiene ratios. The incorporation of X-SBR improved the mechanical properties of the concrete. The data suggest that admixing X-SBR led to denser and more refined microstructure of the cured cement mortar. Compressive strength and Flexural strength graph confirmed such improvements in the pore structure and the formation of an interpenetrating network structure of X-SBR and cement hydrate phases at relatively higher styrene butadiene ratios.View full textDownload full textKeywordsCement hydrate, Compressive strength, Interpenetrating network, X-SBR polymerRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/03602559.2012.702251
