Abstract
Based on a series of experiments, this paper studied the fundamental properties of a new type of high performance fiber reinforced concrete, steel fiber reinforced sulphate-aluminate self-stressing concrete (SFRSC). The direct tensile strength, compressive strength, splitting tensile strength and flexural strength were tested. Through the bonding forces between steel fibers and expansive concrete matrix and the three-dimensional limitation of steel fibers, self-stresses are introduced to SFRSC. Owing to this kind of effects, the strengthening effects of steel fibers on concrete strengths are improved by adding another strengthening coefficient ks to original coefficient αm. Based on the current strength design formulation of steel fiber concrete, the strengthening coefficients are obtained through regressing and optimizing analysis on experimental data. It has been attested that SFRSC could be used as a kind of applicable high performance concrete composite in engineering application.
