关于水泥混凝土发展方向的几点认识

Some Considerations on the Developments of Cement and Concrete

根据在加拿大观察到的重大混凝土工程破坏实例 ,反复强调我国在基建工程中必须十分重视耐久性问题。为实现可持续发展 ,应逐步将水泥工业转变为“绿色胶凝材料工业”。阐述了根据混凝土的技术进步重新审议水泥的标准与组成。最后建议把水泥的生产、流通与使用协调起来 。

According to the cases of deterioration of big concrete structures investigated in Canada, it was repeatedly emphasized to pay attention to durability. In the respect of cement classification it was suggested to cancel “ordinary silicate cement'. The cement industry should be gradually changed to “green industry of cementitious materials'. The standards and compositions of cement should be reviewed on the basis of technical advances of concrete. Finally it was suggested to bring the production, circulation and utilization of cement into line in order to obtain great economic and social benefits. [
