钢纤维对自密实混凝土力学性能影响

自密实混凝土(SCC)相比于普通混凝土具有更加优良的工作性能,无需外力振捣就可依靠自重填充整个模板,因此,被广泛地应用于配筋密集、外形复杂的结构中.配制相同强度等级的自密实混凝土与普通混凝土相比,自密实混凝土所需胶凝材料更多,间接导致自密实混凝土在硬化过程中产生较大的干缩变形,在自密实混凝土中掺加钢纤维,不仅可以有效抑...

Influence of steel fiber on mechanical properties of self-co MPacting concrete

Co MPared with ordinary concrete,self-co MPacting concrete(SCC)has better working performance and can rely on self-weight to fill the whole formwork without external vibration.Therefore,SCC is widely used in the structure with dense reinforcement and complex shape.Preparation of the same strength grade self-co MPacting concrete co MPared with ordinary concrete,the self-co MPacting concrete gelled material more,indirect cause self-co MPacting concrete larger shrinkage deformation occurring in the process of hardening,adding steel fiber in the self-co MPacting concrete,not only can effectively restrain the dry shrinkage of the self-co MPacting concrete,but also can greatly improve the self-co MPacting concrete and the mechanical properties of matrix,and therefore the steel fiber with two materials combined with self-co MPacting concrete steel fiber reinforced self-co MPacting concrete makes sense.Based on previous studies,this paper mainly studies the influence of steel fiber on mechanical properties of self-co MPacting concrete.
