摘　　要：利用平板抗裂法研究了聚乙烯醇纤维和WHDF抗裂减渗剂对混凝土早期抗裂性能的影响,结果表明:在配合比及环境条件相同的情况下,聚乙烯醇纤维能较大幅度地提高混凝土的早期抗裂性能,裂缝数量减少55%,总开裂面积减少83%,但WHDF抗裂减渗剂未达到提高混凝土的早期抗裂性能的效果。Effects of the PVE fiber and WHDF anti-cracking and seepage-reducing agent on the early crack resistance of concrete is studied by the plate crack resistance experiment. The results reveal that the PVE fiber is able to improve the early crack resistance of concrete more effectively than the WHDF agent under the same mixture ratio and environmental conditions. With the PVE fiber, a 55 % decrease is observed in the number of cracks found in the test specimens and 83% decrease in the cracking area. While no obvious effect is observed for the WHDF agent in the improvement of the early crack resistance of concrete.
