PVA-ECC材料性能研究及应用

混凝土以其自身的优点成为使用最广泛的建筑材料,然而水泥基材料收缩大,抗拉强度低,韧性差等本质缺点却没有得到有效地解决,影响了混凝土材料更为广泛的应用。PVA-ECC可以有效地提高水泥基材的韧性,使其呈现应变硬化的特征,并且提高基材的抗拉、抗折强度,使基材呈现多微裂缝开裂特征,从而很好的解决混凝土的耐久性问题。

Research on properties and applications of PVA-ECC

Concrete is the most widely used building materials with its own merits,However,large shrinkage of cement-based materials,the low tensile strength, the nature of disadvantage and poor toughness has not been effectively resolved.All of this has seriously affected the broader their application and thus given rise to many durability problems.The PVA-ECC can effectively improve the toughness of concrete substrate.It presents the characteristics of strain hardening and increases the substrate tensile,flexural st...
