Abstract:
An experimental study was carried out to examine the effects of curing condition on compressive and tensile strengths, water absorption and drying shrinkage of styrene-butadiene latex (SBR)-modified lightweight aggregate concrete (LWAC). The 28-day compressive strength and the dry concrete density were about 40 Mpa and 1500 kg/m3, respectively. The results of the investigation suggest that the compressive and tensile streniths, water absorption and drying shrinkage of the SBR-modified LWAC is less sensitive to the lack of initial moist curing than the unmodified LWAC.
