INFLUENCE OF SBR LATEX ON LONG-TERM DEFLECTION OF HSC BEAMS

Abstract

Using resins in concrete enhance a series of interesting properties such as high erosion resistance to chemical substance such as acids, mechanical properties, frost resistance, impervious to liquids, dampen vibrations, and many other properties. This paper discusses experimentally the effect of SBR Latex into concrete short and long-term deflection of latex modified concrete beams under sustained long-term service loads, effect of SBR latex on compressive strength, and the density of concrete. Four beams were cast and tested with dimensions (150×150×750) mm; the experimental parameters included was the replacement ratio of SBR added (0, 5, 10, 15) %, and the concrete strengths. The test results showed that the trend of long-term performance of concrete beams was comparable to those without SBR Latex. Furthermore, the test results showed that with the increase of SBR ratio, the compressive strength and the long-term deflection multiplier were reduced.
