摘要
对4组不同配比的普通活性粉末混凝土 (RPC)及4组不同配比的钢管活性粉末混凝土 (钢管RPC)轴压短柱进行极限抗压强度实验。结果表明 ,同以往的钢管高强混凝土相比 ,钢管对RPC的极限抗压强度有更好的提升效果,并且在钢管的约束下 ,RPC内部的缺陷发展得到了有效的抑制。
Two series of short columns, one is made of Reactive Powder Concrete(RPC) and other is made with 4 Steel Pipe RPC, are experimented under uniaxial compression for measuring the ultimate strength. The results show that, compared with ordinary Steel Pipe hight-strength Concrete, the Steel Pipe RPC has more increasing in ultimate compressive strength. And the propagation of inner defects of RPC can be effectively prevented owing to the restraint of steel pipe.
