如何准确及时地对水泥强度进行快速测定,是施工现场急待解决的问题。自实行水泥新标准以来,我们进行了多种方法的试验,根据我公司设备条件,选定了“蒸养法”快速测定水泥标号的方法,经一年多的试验和施工实践,其准确率达到95%左右,个别误差在10%上下,效果较好。此法操作简便,不增加任何仪器设备,经30个小时的快速测定,可推算出28天的标准强度,向施工现场准确地提供试验报告,为加快施工进度,合理使用原材料,保证工程质量,起了一定作用。一、试验方法 1.按软练标准(GB177-
How to accurately and timely determine the strength of cement is an urgent problem to be solved at the construction site. Since the implementation of the new cement standard, we have conducted a variety of tests. According to the conditions of our company’s equipment, we have selected the method of rapid determination of the cement label by the “steam curing method”. After more than one year of tests and construction practices, the accuracy rate Achieve 95% or so, individual error is about 10%, the effect is better. This method is easy to operate, does not add any equipment, after 30 hours of rapid determination, can calculate the standard strength of 28 days, to provide accurate test reports to the construction site, in order to speed up the construction progress, the rational use of raw materials, to ensure project quality, Played a role. First, the test method 1. According to the soft standard (GB177-
