高强度的钢纤维混凝土配制要求
(1)配制要求
(1) Preparation requirements
为了获得高强度的钢纤维混凝土,必须满足以下条件:
In order to obtain high strength steel fiber reinforced concrete, the following conditions must be met:
1)具有足够数量和匀质的高强钢纤维;
1) High strength steel fibers with sufficient quantity and homogeneity;
2)在整个工艺过程中,钢纤维仍保持自身的大部分强度;
2) During the whole process, steel fibers still maintain most of their strength.
3)纤维同混凝土的粘结力较好,纤维同砂浆接触部分的密实度较高;
3) The bond strength between fiber and concrete is better, and the density of the contact part between fiber and mortar is higher.
4)纤维应均匀分布在基体材料的整个体积中;
4) The fibers should be evenly distributed in the whole volume of the matrix material.
5)基体材料对纤维应是化学惰性的;
5) Matrix material should be chemically inert to fibers.
6)基体材料应具有足够的抗剪强度。
6) The matrix material should have sufficient shear strength.
