Analysis of the influence of test method and properties of steel fiber addition on concrete under the three-point flexural tensile

ABSTRACT The characterization of steel fiber reinforced concrete with dry consistency require greater inspection the account of the particularities in the process of mixing, molding and densification, thus this paper aims to propose a methodology combined of densification by manual and mechanical me...
