摘要
研究了机械磨平、水泥净浆补平、硫磺胶泥补平等三种混凝土芯样端面处理方式对其抗压强度的影响。结果表明:采用硫磺胶泥补平方式,芯样抗压强度平均值最高,采用水泥净浆补平略低,采用机械磨平方式则最低。假设性经验分析得出,采用硫磺胶泥补平与水泥净浆补平的抗压强度不存在显著性差异。采用硫磺胶泥补平方式,加工过程最稳定,试验结果分布最集中,采用水泥净浆补平次之,采用机械磨平的试验结果分布最离散。
Effect of end face treatments of concrete core sample on its compressive strength was studied.The results showed that average value of compressive strength was highest with sulphur mastic level manner,and paste level manner taked second place,mechanical polish was the lowest.The result of hypothetical test showed that sulphur mastic level manner and paste level manner had no significant difference in average value of compressive strength.Distribution of test results with sulphur mastic level manner was the most concentrated,and paste level manner take second place,mechanical polish was the most scattered.
