水泥混凝土是当代最大宗的人造材料。根据1970年美国资料的统计,全世界年产量超过40亿吨,即每人每年平均1吨,而发达国家每人每年达3～4吨。由于混凝土具有原料丰富、成本较低、防火耐久、节省能量消耗以及有利于环境保护和发展组合材料等特点,在一、二百年内仍将是最主要的建筑材料之一。因此混凝土科学技术受到普遍重视,比较发达的国家都有几种以至几十种混凝土及其制品、构件的科技刊物,一些发展中国家也公开发行一、二种混凝土期刊。现在我国广大混凝土工人和科技人员盼望已久的《混凝土及建筑构件》双月刊正式 Cement concrete is the largest man-made material in the world. According to the statistics of the United States in 1970, the annual output of the world exceeds 4 billion tons, that is, an average of 1 ton per person per year, while the developed countries each reach 3 to 4 tons per year. Because of its rich raw materials, low cost, long-lasting fire protection, energy saving, and environmental protection and development of composite materials, concrete will remain one of the most important building materials within one or two hundred years. Therefore, concrete science and technology have received universal attention. Several developed countries have several kinds of concrete publications and their products and components. Some developing countries also publicly issue one or two concrete periodicals. Now China’s vast concrete workers and scientists and technicians have long been looking forward to the bimonthly “concrete and building components” official
