研究了多孔陶瓷废料粗骨料(PCWA)作为内养护剂对掺入质量分数分别为0%、20%和40%的粉煤灰蒸养混凝土抗压强度、收缩性能和抗碳化性能的影响。聚氯乙烯的置换率分别为粗集料体积的0%、10%和20%。结果表明，掺40%FA的PCWA能显著提高混凝土的抗压强度和抗碳化性能，而掺40%FA的蒸养混凝土的干缩率有所增加。
This study aims to investigate the effects of porous ceramic waste coarse aggregate (PCWA), which was used as an internal curing agent, on the compressive strength, shrinkage, and carbonation resistance of steam-cured concrete using fly ash (FA) at the replacement ratios of 0%, 20%, and 40% by mass. The PCWA replacement ratios amounted to 0%, 10%, and 20% of the coarse aggregate volume. The results showed that the PCWA significantly improved compressive strength and carbonation resistance of concrete using 40% FA, whereas it could increase the drying shrinkage of the steam-cured concrete using 40% FA.
