纤维水泥增强机理的研究

Investigation of the strengthening mechanism of fibre cement

本文对纤维水泥的增强机理进行了研究。在分析它与纤维混凝土之间的异同点之后,在复合力学理论基础上引入折减基体弹性模量的概念,使两种增强机理得到了统一,该方法解释了直接引用复合力学理论对纤维水泥所不能解释的现象。

In this paper the strengthening mechanism of fibre cement is studied. A concept of discounted elastic modulus usually used in the composite material mechanics is introduced to clarify the real difference of strengthening mechanisms between the fibre reinforced concrete and fibre cement. Then an unified mechanism of strengthening is established. This mechanism is able to explain some phenomena occurring in fibre cement which can't be explained by composite material mechanics.
