Effect of Anti-alkaline Additives on the Strength of Steel Fiber Reinforced Concrete
摘要
Abstract
For studying the influence of the anti-alkaline additives on the basic mechanical properties of steel fiber reinforced concrete, the bending and compressive tests of steel fiber reinforced concrete mixed with or without anti-alkaline additives are carried out. The specimen varied with the water-cement ratio and steel fiber volume fraction. The test results show that the addition of the anti-alkaline additives to concrete has almost no effect on the compressive strength of ordinary concrete, but has the effect less than 10％ on the compressive strength of steel fiber reinforced concrete. Compared with steel fiber reinforced concrete without anti-alkaline additives, the bending strength of steel fiber reinforced concrete mixed with anti-alkaline additives is higher and the increasing extent decrease with the increase of compressive strength. In addition, anti-alkaline additives can improve the ratio of bending strength to compressive strength of ordinary concrete and steel fiber reinforced concrete, the average increasing extent of the ratio is about 8.8％.关键词
