摘要
该文提出采用砂盒法检测混凝土芯样抗压强度,论述其作用原理,并进行验证试验,同时与补平法及磨平法的试验结果进行对比分析。结果表明,砂的细度模数是砂盒法试验的主要影响因素,试验时应选用中砂;采用砂盒法试验的混凝土芯样抗压强度结果与磨平法较接近,而补平法的试验结果则比磨平法和砂盒法偏低。
Sandbox method was put forward to test compressive strength of concrete core sample in this paper, the action principle was discussed while verification testing. Simultaneity, the compressive strength results of sandbox method,smoothed method and filling method were compared analysis. The results indicated that fineness modulus of sand was main influence factor and medium sand should be selected in sandbox method; the compressive strength re- sult of concrete core sample by sandbox method was close to smoothed method, and the compressive strength result by filling method was lower than other two methods.
