最近收到读者来信,要求本刊对我国水泥新标准作些介绍。现由水力发电建设总局吴来峰同志根据有关资料写成这篇简介,以偿读者。 Recently received a letter from the reader, asked the magazine on China’s new cement standards for some introduction. At present, Comrade Wu Laifeng of the General Administration of Hydroelectric Power Construction has written this brief introduction on the basis of the relevant materials for the readers.
