由于节能及环境保护的需要,国外粉煤灰在结构工程上的利用越来越受重视。本文作者曾在瑞典水泥及混凝土研究所及瑞典水泥公司研究粉煤灰水泥的水化;1981年4月曾参加了在墨西哥召开的以火山灰质材料利用为主题的国际混凝土工艺会议,考察了美国、加拿大的水泥(包括粉煤灰水泥)的科学研究情况;有机会了解和阅读到一些西方国家粉煤灰利用及科 Due to the need for energy conservation and environmental protection, the use of foreign fly ash in structural engineering has received increasing attention. The author of this paper studied the hydration of fly ash cement at the Swedish Cement and Concrete Research Institute and the Swedish Cement Corporation. In April 1981, he participated in the International Concrete Technology Conference on the use of volcanic ash materials in Mexico and examined the United States. , Canada’s cement (including fly ash cement) scientific research; have the opportunity to understand and read some Western countries fly ash utilization and Branch
