摘要
面对可持续发展的挑战,混凝土主要原材料需要调整生产与合理使用。减少或保持现有硅酸盐水泥熟料的产量,以减少向大气排放CO2;水泥总体产量可以通过大掺量工业废料来满足建设的需要,以减小对环境的压力;骨料生产和质量亟待很大的改善,以尽量减少混凝土的用水量;此外必须从可持续发展的高度,重视和考虑混凝土结构的耐久性。
Facing challenge of sustainable development, it's necessary to adjust the production and use reasonably the main raw materials of the concrete. Decreasing or maintaining the present output of clinker may reduce discharge of CO2 to atmosphere. The total output of the cement mixed a lot of industrial waste materials may meet the requirement of construction,to reduce the pressure on the environment.The production and quality of the aggregate should be improved greatly to minimize the water demand in concrete.In addition,the durability of the concrete structure should be considered and paid more attention to,according to the sustainable development height.
