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.

High Performance Steel

An experimental investigation was conducted on behavior of high performance steel-fiber concrete subjected to high temperature, in terms of explosive spalling and permeability. A series of concretes incorporated steel fiber at various dosages were prepared, and further processed to have a series of moisture contents. Explosive spalling tests were conducted on control plain concrete and steel fiber concrete. After explosive spalling tests, each of the specimens that didn’t encounter spalling was sawn into two pieces. Crack observations and permeability tests were conducted on the sawn surfaces. The results prove that steel fiber is efficient to avoid spalling concrete under high temperature. The permeability increases significantly after thermal exposure, while it also exhibits an ascending trend with the increase of moisture content. Therefore it is concluded that steel fiber can play a positive effect on explosive spalling of high performance concrete under high temperature, as well as on permeability after thermal exposure.

Mechanical properties of steel fiber concrete under dynamic load had been obtained through dynamic loading experiments of steel fiber concrete in different volume ratios. The experimental results indicate that the dynamic load strength of steel fiber concrete is obviously more than the static load strength, the dynamic load strength increases with the increasing of the steel fiber volume ratio; and the effect of variable strain rate is obvious. When the strain is at 0 ~ 0.01 or smaller, the toughness index of plain concrete is slightly more than steel fiber concrete; the strain exceeded 0.01, the toughness of steel fiber concrete has improved greatly with the increase of the strain. When the strain rate is smaller, the elastic modulus changes little, and once the strain rate is more than 60 per second, the elastic modulus there is the more amplitude with the increase of strain rate.

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.
