我国在建筑工地上使用散装水泥已有十多年的历史,由于国家的重视,使这项工作有了很大的发展,取得了一定成绩。但与国外工业先进国家相比还有不少差距。 散装水泥在国外已受到了各国的普遍重视,一些水泥工业比较发达的国家均已大量采用,例如美国、苏联、 China has used bulk cement for more than a decade in construction sites. Due to the country’s attention, this work has made great progress and has achieved certain results. However, there are still many gaps compared with foreign advanced industrial countries. Bulk cement has received widespread attention from various countries in the world, and some countries with relatively advanced cement industries have adopted a large number, such as the United States and the Soviet Union.
