The article presents the results of experimental and theoretical studies of strength and deformability of steel-fiber concrete double-sided pre-stress slabs under the action of transverse loading. The simulation of such plates in the software complex LIRA-SAPR was performed taking into account the physical nonlinearity of materials.

Steel Fiber Concrete

To increase the efficiency of steel-fiber concrete production, the existing technological operations that could reduce the costs should be optimized. This process requires scientific research and analysis of the existing results to improve the efficiency of each production stage. One of the important stages in the steel-fiber concrete production is steam curing, which is responsible for forming the cementitious matrix structure. To increase the efficiency of this production stage, a study was conducted to develop the steam curing conditions according to the rules of steel-fiber concrete structure formation and the methods of improving durability indicators. Tests on several steel-fiber concrete compositions were conducted, and the relations between its thermal conductivity and the reinforcement coefficient of concrete were revealed. The results of the tests let us conclude that with the increase of the reinforcement coefficient its thermal capacity decreases. The temperature gradient charts along the cross-section of samples with different cement/sand ratios and reinforcement coefficients were built. According to the data obtained, the optimal industrial conditions of steam curing were discovered. The dependences determining the increase of mechanical performance of steel-fiber concrete due to the formation of prestressed fiber structure in the material were revealed.

For getting the mechanics and contact explosion capability parameters, some new steel fiber concrete samples with 5% steel fiber were tested, many groups data were obtained with compress strength, shear strength and fracture toughness. The model tests were carried out on the new steel fiber concrete under contact explosion, the coefficient of explosion cavity radius of the material is obtained by above experiments and theory study. The two kinds of experiments above point out, the new steel fiber concrete with steel fiber has very high strength and rupture temper and its capability anti-explosion is about three times than general concrete.
