doi:10.3969/j.issn.1674-0696.2012.05.09

Abstract

Abstract: Based on the regular method used in the controlling concrete cracks，the feasibility of PVA fiber in controlling the concrete cracks in order to reduce or to eliminate the early-age plastic shrinkage and cracking was discussed． Properties of anti-cracking and shrinkage of the samples were studied by board device and splitting tensile strength test． The shrinkage resistance capability of samples with different contents of high modulus PVA fiber with diameter 14 μm was studied experimentally． The test results indicate that the early-age plastic shrinkage cracks can be eliminated and the tensile strength will be increased when the volume content of PVA fiber in concrete is 0． 6%．

Key words: Polyvinyl Alcohol( PVA) fiber, concrete, shrinkage, crack, tensile strength

摘要： 为减少或消除混凝土早期塑性收缩开裂，在常用的控制混凝土裂缝方法的基础上，探讨了添加PVA 纤维控制混凝土裂纹的可行性。采用平板法塑性收缩试验和劈裂抗拉试验，对比研究了直径为14 μm 的，不同掺量的高模量 PVA 纤维混凝土抗收缩性能。研究结果表明:当PVA 纤维体积掺量为0． 6% 时，可消除早期塑性收缩裂纹，提高混凝土的抗拉强度。
