The influence of steel fiber for its allocation in the cement-sand matrix
Article deals with the results of the geometric characteristics of steel fiber various types influence on its allocation in the cement-sand matrix of sheet steel fibre concrete products. These tests were performed by the Institute Orgenergostroy.It is shown that length, diameter and weight of the fiber, as well as the percentage of the fiber reinforcement and the presence of anchors on its ends can influence on the character of fiber allocation. During selection of the cement-sand matrix steel fiber concrete composition and cement-sandy matrix one should take into account the mobility of cement-sand mixture and its viscosity as well
