摘要
依据试验数据分析了环境条件及龄期对钢纤维混凝土抗压强度的影响,结果表明龄期对钢纤维混凝土强度的影响,与普通混凝土一致;环境条件通过影响基体的界面结构以及基体和钢纤维的粘结,从而影响钢纤维混凝土的抗压强度.并就成熟度与钢纤维混凝土强度之间的关系进行了初步的探索,建立了相应的经验公式.
According to the information of concrete testing, the relation between environment requisition and age and compressive strength of steel fiber reinforced concrete is analysed. The result indicates that the law of compressive strength of steel fiber reinforced concrete influenced by age of concrete is consistent with common concrete; interface structure of radical body and felt of radical body and steel fiber is affected by environment condition, which influences compressive strength of steel fiber reinforced concrete. And the relation between maturity and the strength of steel fiber reinforced concrete is explored firstly, establishing the homologous empirical formula.
