【摘要】：普通混凝土具有许多优点,但其脆性大、易产生开裂,这将导致外界化学介质向内部扩散的速度加快,使建筑结构的使用寿命大幅度降低。加入聚乙烯醇纤维是解决这一问题的一种有效途径,并且能够显著改善水泥基材料的性能。论文介绍了聚乙烯醇纤维增强水泥基复合材料的国内外研究现状、动力学特性以及自愈合情况,探讨了该材料的微观设计理论,介绍了其应用,并对聚乙烯醇纤维增强水泥基复合材料研究进行了展望。
[Abstract]:Ordinary concrete has many advantages, but its brittleness is large, easy to produce cracking, this will lead to the speed of the diffusion of external chemical media to the internal faster, so that the service life of the building structure is greatly reduced. Adding polyvinyl alcohol fiber is an effective way to solve this problem and can improve the properties of cement based materials. This paper introduces the research status, dynamic characteristics and self-healing of polyvinyl alcohol fiber reinforced cement matrix composites at home and abroad, discusses the micro design theory of the material, and introduces its application. The research of polyvinyl alcohol fiber reinforced cement matrix composites is also prospected.
