摘　　要：研究了纤维素纤维、PVA纤维及其混杂掺入对混凝土抗裂性能的影响。试验结果表明:纤维素纤维、PVA纤维均能有效提高混凝土的劈裂抗拉强度和早期抗裂性能;PVA纤维和纤维素纤维混杂掺入使混凝土的抗裂效果有明显改善。依托工程的应用表明,用于地下工程墙板中的粉煤灰、矿粉"双掺"纤维混凝土具有良好的抑制早期裂缝开展的作用。The influence of cellulose fibre,PVA fiber and hybrid fiber on concrete anti-cracking performance.Experimental results show that the cellulose fibre,PVA fibers are can effectively improve the splitting tension strength and resistance to early shrinkage performance,and the both hybrid fibers concrete anti-cracking effects have been improved obviously.The engineering practice shows that the application in underground engineering wallboard of fly ash and slag ＂double mixing＂ fiber reinforced concrete has good fracture resistance.
