混凝土产业面临的环境问题及其原因分析

绿色混凝土的基本理念

当前在此领域的一些尝试

现阶段存在的问题以及今后的发展方向

每生产一吨的 Portland 水泥释放出两吨的二氧化碳

生产混凝土时需要大量的水

废弃的混凝土总量巨大

Problems

水泥生产方面：

生产工艺相对比较成熟

用其他的胶凝材料替换混凝土中所使用的水泥

用水量控制方面：

由于用水量直接影响混凝土的强度等关键因素，因此控制用水量的研究比较深入，解决方法也不少

固体废料方面：

废弃的混凝土处理困难，对环境影响较大

废弃方面

生产方面

使用方面

What's Green Concrete？

节约资源、能源；

不破坏环境，更应有利于环境；

可持续发展，保证人类后代能健康、幸福地生存下去。

其中，第二条是第三条的保证。

节约资源、能源；

保护环境

Problems

竹子的纤维分布及其组成使得它具有平行方向的高强度，垂直方向的低强度

从混凝土和易性，抗压强度，氯化物渗透性多方面进行了评价，并且与添加硅灰以及空白的同等级混凝土的数据进行了比较
