生态混凝土的研究进展与问题探讨

Research on eco-concrete and discussion about related issues

生态混凝土是20世纪90年代开始进行研究与运用的新型建筑材料。它的多孔结构使其拥有良好的透水、透气和吸附能力,在透水混凝土、绿化混凝土等方面应用十分广阔,具有良好的生态与环境效应,减轻普通混凝土造成的巨大环境负荷。本文在对生态混凝土的研究、应用现状进行评述的基础上,对其存在低强度、碱性、耐久性等问题进行分析,提出加大生态混凝土研究力度,积极对胶凝材料进行改性,结合利用混凝土再生利用技术,建立合理的设计与评价体系,提高行业意识等对策和措施,综合解决生态混凝土发展中的难点,文章最后对生态混凝土发展前景进行了预测展望。

Eeo-conerete ,a new building material, is researched and used at the beginning of the 20th century 90＇s. Compared with traditional concrete it has many advantages. Duo to its porous structure it has good water, air permeability and adsorption capacity. Eco-concrete is widely used in permeable concrete and green concrete. This has a good ecological and environmental effects and reduces enormous environmental load. In this paper, we analyse low in- tensity, alkalescence, durability and so on based on the status quo of research and application for eco-concrete. Research on eco-conerete should be reinforced and the improvement of cementitious materials＂ characteristics is requisite. To solve difficultis in the development of eco-concrete, a rational design and evaluation system need to establish combined with the use of concrete recycling technology and raising the industry awareness. Finally this paper predicts the future development prospects of eeo-concrete.
