Experimental study on the compressive strength of grouted concrete block masonry based on nondestructive detection methods

Existing nondestructive detection methods were adopted to test the compressive strength of grouted concrete block masonry,i.e.the rebound method,pulling-out method and core drilling method were employed to test the strength of block,mortar and grouted concrete,respectively.The suitability of these methods for the testing of strength of grouted concrete block masonry was discussed,and the comprehensive strength of block masonry was appraised by combining existing nondestructive or micro-destructive detection methods.The nondestructive detection test on 25 grouted concrete block masonry specimens was carried out.Experimental results show that these methods mentioned above are applicable for the strength detection of grouted concrete block masonry.Moreover,the formulas of compressive strength,detection methods and proposals are given as well.

振动搅拌技术在水泥稳定碎石基层中的应用

为研究振动搅拌技术对水泥稳定碎石性能的影响,本文以某公路水泥稳定碎石基层施工为背景,通过检测水泥稳定碎石原材料性能并进行室内强度试验,来研究水泥稳定碎石在实际工程中的施工工序及施工应用效果。研究结果表明:随着水泥稳定碎石水灰比及养护龄期的增加,其无侧限抗压强度及劈裂强度均增加,且在同等水灰比及养护龄期下,振动搅拌成型试件强度均大于普通成型试件;振动搅拌成型试件抗压强度BDR(耐冻系数)优于普通搅拌成型试件;水泥稳定碎石基层施工完成后,检测得出压实度及平整度均满足规范要求,这表明振动搅拌在水泥稳定碎石中具有较好的应用效果。
