摘要:

低碳超高强石渣混凝土是作者利用地方原材料自主研发的强

度达到137.3MPa的新型环境友好型混凝土.本文通过14个试件的轴

心抗压试验,考察并分析了钢管约束超高强石渣混凝土的破坏形态,

研究了影响核心混凝土强度增长率的因素和规律.试验结果表明:

钢管内填充低碳超高强石渣混凝土可以解决由于自收缩偏大引起的

钢管混凝土脱空的问题;在试验参数范围内,钢管约束超高强石渣混

凝土的强度增长率与套箍指标成正比;低碳超高强石渣混凝土用钢

管约束后脆性性能得到显著的改善,位移延性系数达到6.5~26.3;所

有的试件都是因为剪切而破坏,同时对其破坏机理进行了分析.

Abstract:

Green super high strength concrete used stone

chip (abbreviated to GSHSCUS) is a new kind of

environmentally friendly concrete with the strength

being as high as 137.3 MPa, which were developed by the

authors with the local materials. Based on the

experimental studies of 14 specimens, this paper

describes the failure mode of GSHSCUS filled with steel

tubes, and try to discover the general regularity. It

was found that it is possible for us to deal with

disengaging due to selfshrinkage at interface of steel

tubeconfined concrete by filling GSHSCUS ,and

experiment results show that within the factor scope of

this test, the strength growth rate of GSHSCUS filled

with steel tubes is almost proportional to the

confinement index of the specimens, and that all

specimens exhibits excellent ductility, and shear

failure. Also analyzed is the mechanism of failure of

the specimens.
