干湿循环对水泥稳定风化砂强度的影响

Influence of Dry-wet Cycle on Strength of Cement Stabilized Weathered Sand

对3%水泥稳定风化砂进行干湿循环试验,研究干湿循环作用下试件强度特性的变化规律。结果表明,干湿次数的增加会降低试件的无侧限抗压强度,前6次干湿作用对水泥稳定风化砂的强度影响较大,强度损失率超过36%,后6次干湿作用对强度影响较小。

The dry-wet cycle test was carried out on 3% cement stabilized weathered sand, and the change law of the strength characteristics of the specimen under the action of the dry-wet cycle was studied. The results show that the increase of the number of wet and dry times will reduce the unconfined compressive strength of the specimens. The first 6 dry and wet effects have a greater impact on the strength of cement stabilized weathered sand, and the strength loss rate exceeds 36%. The last 6 dry and wet effects Less impact on strength.
