dc.description.abstract | Effects of air entrainment on rheological parameters and slump of fresh lightweight aggregate concrete were studied. Results show that yield stress and plastic viscosity of air-entrained concrete were lower than those of non-air-entrained concrete with similar superplasticiser dosage. As the entrained-air content increased, the plastic viscosity decreased whereas the yield stress remained relatively unchanged. The slump of the air-entrained concrete was significantly higher than the non-air-entrained concrete. At similar yield stress, the slump of the air-entrained concrete was higher owing to its lower plastic viscosity by air entrainment. At similar slump, the air-entrained concrete had higher yield stress and lower plastic viscosity, implying that higher shear stress is needed to initiate flow but flow resistance would be lower. | |
