建国30多年来,建材工业有了很大的发展。以水泥为例,从1953年到1982年,水泥产量增加了24倍。但随着工农业与城乡建设的迅速发展,水泥的供需矛盾仍然十分突出,统配水泥的缺口每年达数百万吨。为了实现到本世纪末工农业总产值翻二翻的宏伟目标,不仅要大幅度增产质量好、成本低、能耗省、劳动生产率高的统配水泥,而更重要的是,如何在提高技术经济效益的前提下用好水泥。众所周知,水泥混凝土是国民经济建设中用量最大的一种建筑材料。长期以
In the 30 years since the founding of the People’s Republic of China, the building materials industry has made great progress. Taking cement as an example, from 1953 to 1982, cement production increased by 24 times. However, with the rapid development of industry and agriculture and urban and rural construction, the contradiction between the supply and demand of cement is still very prominent, and the gap of the cement distribution is millions of tons per year. In order to realize the grand goal of doubling the total output value of industry and agriculture by the end of this century, not only must we significantly increase the production of good quality, low cost, energy-saving, and high labor productivity, but more importantly, how to improve the technical economy. Good use of cement on the premise of efficiency. As we all know, cement concrete is one of the largest building materials used in the national economy. Long term
