In order to study the mechanical properties of steel fiber rubber recycled brick concrete, ten groups of recycled brick concrete specimens with the strength of 15MPa were tested , one group was purely recycled brick concrete, the remaining nine groups mixed with different rations of admixture. Three groups mixed with steel fiber, another three groups mixed with rubber granules, the last three groups mixed with both steel fiber and rubber granules. These concrete specimens were tested by pressure testing machine respectively, the maximum strength is calculated by its maximum stress value. The results proved that: when adding steel fiber to recycled brick concrete can improve the strength of concrete, the higher the percentage of steel fiber was added, the more obvious the increases in strength. The recycled brick concrete mixed with rubber granules showed a reduced strength of the concrete, the higher percentage of rubber granules were added, the more significant drop in strength. When added the same percentage of both steel fiber and rubber granules, the result showed an increased strength of recycled brick concrete, as the percentage of two kinds of admixture dosage increases simultaneously, the strength increases rapidly.
