欣逢《混凝土与水泥制品》问世,编辑部同志要我谈谈感想与希望。综观几千年建筑材料的发展史,材料和建筑总是交替地相互推动前进的。一百多年来,波特兰水泥和各种混凝土的发明,大大改变了建筑工程的面貌。这就是材料革命推动了建筑革命。现在混凝土不仅成为最主要的建筑材料,并且也是当代最大宗的人造材料。由于原料来源丰富,还能利用大量的工业废渣,由于能耗较低,很多预应力混凝土构筑物比相同功效的钢结构省能达50％之
Yan Feng’s “Concrete and Cement Products” came out, and the editorial comrades asked me to talk about their feelings and hopes. Looking at the history of the development of building materials for several thousand years, materials and buildings always alternately push each other forward. For more than one hundred years, the invention of Portland cement and various concretes has changed the face of construction projects. This is the material revolution that promoted the architectural revolution. Now concrete is not only the most important building material, but it is also the largest man-made material in the world. Due to the abundant source of raw materials, a large amount of industrial waste can also be utilized. Due to the low energy consumption, many prestressed concrete structures can save up to 50% of the energy of the same effect of the steel structure.
