As a ceramic-like material, geopolymers show a high quasi-brittle behavior and relatively low fracture energy. To overcome this, the addition of fibers to a brittle matrix is a well-known method to improve the flexural strength. Moreover, the success of the reinforcements is dependent on the fiber-matrix interaction. In this present study, effects of micro steel fibers (MSF) incorporation on mechanical...
Based on the compressive strength, flexural strength and freeze-thaw test of the steel fiber reinforced concrete (SFRC) mixed with fly ash, the influence of different fly ash mixing on the basic mechanical properties of steel fiber reinforced concrete and freeze-thaw effect were analyzed, and the thawing mechanism of steel fiber reinforced concrete with high mixing of fly ash was discussed. The test...
