国标JB1344-85中规定:“水泥在运输与保管时不得受潮和混入杂物,不同品种和标号的水泥应分别贮运,不得混杂。”但在建筑工地上水泥由于保管不慎发生混合,或某种水泥发生短缺需用另一种水泥进行补充等情况常常遇到。浙江省程斌同志来信问“能否用两种不同水泥(同标号不同厂或同厂不同标号)混合,用于浇捣混凝土构件”这里我们选用河南信阳地区建筑公司技校赵仁同志的文章作为答复。
According to the national standard JB1344-85, “Cement must not be exposed to moisture and mixed with debris during transportation and storage. Different types and grades of cement should be separately stored and transported, and must not be mixed.” However, due to careless storage of cement on the construction site, mixing occurs. , or the shortage of some kind of cement needs to be supplemented with another kind of cement, etc. are often encountered. Comrade Cheng Bin of Zhejiang Province sent a letter asking “Can we use two different types of cement (the same label with different plants or different labels of the same plant) to mix concrete components for pouring?” Here we use Comrade Zhao Ren from Technical School of Henan Xinyang Construction Company.
