配合国标《混凝土小型空心砌块试验方法》GB/T4111修订工作,对拟议中的砌块抗压强度试验方法进行验证性试验。探讨采用不同抹面材料、抹面方法、压力试验机加载方式等,对混凝土砌块抗压强度值检测结果的影响。试验结果表明:试验机加载方式对检测值影响最大,试件制作精度其次;不同抹面材料对检测值有影响,但不明显。
In line with the national standard “small concrete hollow block test method” GB / T4111 revised work on the proposed block compressive strength test method for confirmatory test. The effects of using different plaster materials, plastering methods and loading methods of pressure testing machine on the test results of compressive strength of concrete block are discussed. The test results show that: the test machine loading method has the greatest impact on the test value, the second is the precision of the test piece; different plaster materials have an impact on the test value, but not obvious.
