影响中含量钢纤维高强砼强度若干因素的试验研究

Test study on influential factors of median concrete steel fiber reinforced concrete with high strength

采用现场最普通的搅拌、成型方法 ,研究了钢纤维长度、体积率、水灰比、骨料最大粒径和级配对中含量钢纤维砼抗压和抗拉强度的影响 ,找出了影响中含量钢纤维砼强度的主要因素 ,得出了中含量钢纤维砼强度和钢纤维体积率的关系式 图 6,表 2 ,参

With the experiment adopting the method of blending, formation, the article illustrates that the length and volume ratio of steel fiber, water-cement ratio, maximum aggregate size, grading of aggregate are of different influence on the tensile splitting and compressive strength of the median content steel fiber reinforced concrete, finds out the influencial factors on the median content steel fiber reinforced concrete, and draws the formula between the strengh of median content steel fiber reinforced concrete and the volume ratio of steel fiber.6figs.,2tabs.,5refs.
