1980年7月参加在法国巴黎举行的第七届国际水泥化学会议,1981年6月又到美国参加筹备1980年在巴西举行的第八届国际水泥化学会议的科学委员会,访问了美、法几个主要的水泥混凝土科研单位,与外国学者就水泥混凝土的科技发展近况与存在的主要问题交换了意见。有些问题具有普遍性,在技术发达的国家如美、法、苏、日等国存在,在我国也同样存在。研究解决这些问题,将加速我国水泥混凝土科学技术的发展,在四化建
In July 1980, he participated in the 7th International Conference on Cement Chemistry held in Paris, France. In June 1981, he went to the United States to participate in the preparation of the Scientific Committee of the 8th International Cement Chemistry Conference held in Brazil in 1980. He visited the United States and France. The major cement concrete research units exchanged views with foreign scholars on the current state of science and technology development of cement concrete and the major problems that existed. Some problems are universal and exist in countries with advanced technologies such as the United States, France, the Soviet Union, and Japan, and they also exist in our country. Researching and solving these problems will accelerate the development of China’s cement concrete science and technology, and will be built in Sihua.
