摘要:
在分析渍浆纤维混凝土(SIFCON)和渍浆网片混凝土(SIMCON)各自优缺点的基础上,研究了不同性质乱向短纤维和定向纤维网片复合及不同性质网片组合方式对纤维增强混凝土性能的影响.实验结果表明:各种纤维体积分数下定向网片与乱向短纤维复合增强混凝土各项性能明显优于单用乱向短钢纤维增强混凝土; 当纤维总体积分数为8%时,由2层细孔编织钢丝网和3层细孔玻纤网组合网片型式B(网片体积分数为0.7%)与乱向短纤维(体积分数为7.3%)复合增强混凝土,其抗弯强度、抗剪强度、弯曲韧性(I5
Abstract:
The effect of the hybrid composite manner of disordered short steel fiber and mat on the properties of fiber-reinforced fly-ash cement-based materials is presented in this paper.Test results show that better properties of mat and disordered short steel fiber reinforced concrete can be achieved, especially when the total fiber volume ratio is 8%(mat volume ratio 0.7%, short steel fiber volume ratio 7.3%)in composite manner of B. That is, when two layers of steel wire knitted mesh(5 mm×5 mm)and three layers of glass fiber web(5 mm×5 mm)are used as composite mat,the flexural strength, shear strength and flexural toughness(I5)are increased by 45%,25% and 46% respectively more than that of the disordered short steel fiber reinforced concrete. The synergetic effect of hybrid fiber and mat reinforced concrete with different fiber elasticity moduli and orientations in microstructure and macrostructure is revealed, and a kind of high performance fiber reinforced cement based material is manufactured at relatively low cost in a convenient way for construction.
