摘要:

通过立方体试块的抗压试验,研究了钢纤维体积率、钢纤维类型、浇筑方式、粉煤灰置换率对自密实混凝土抗压强度的影响.结果表明,钢纤维提高了自密实混凝土的抗压强度;在钢纤维体积率的一定范围内,振捣改善了钢纤维对自密实混凝土抗压强度的增强效果;自密实混凝土的抗压强度随着粉煤灰置换率的增加而降低,随着龄期的增长而逐渐提高.在试验研究的基础上,给出了粉煤灰置换率为20%,30%的自密实混凝土立方抗压强度随龄期变化的计算公式.

Abstract:

Through the compressive test of the cube test block, the effects of steel fiber volume rate, steel fiber type, pouring method and fly ash replacement rate on the compressive strength of self-compacting concrete were studied. The results show that the steel fiber improves the compressive strength of self-compacting concrete. Within a certain range of steel fiber volume ratio, vibration improves the strengthening effect of steel fiber on the compressive strength of self-compacting concrete. The compressive strength of self-compacting concrete decreases with the increase of fly ash replacement rate, and gradually increases with the increase of age. On the basis of experimental research, a calculation formula for the cubic compressive strength of self-compacting concrete with fly ash replacement rate of 20% and 30% with age is given.
