    4.节约能源,提高混凝土的性价比,降低水泥用量,节约能源。多掺混合材(高炉矿渣细粉、粉煤灰等量或超量替代水泥)可降低成本,提高性价比。

    5.高性能外加剂(高效减水剂、水泥精等)不仅能克服混凝土坍落度损失大的缺点,还能改善混凝土孔结构和密实性,减少混凝土的徐变度,保证混凝土强度。

    混凝土外加剂的选择

    混凝土向高性能方向发展是今后的科研重点。目前,混凝土中应用最广泛、效果较好的外加剂是高效减水剂。专利产品H-2水泥精(原SHJ-1A石灰精升级换代产品)更以其卓越的性能在外加剂行列中占有重要的地位。

    粉煤灰含有大量的玻璃微珠,具有滚珠轴承作用,可降低水泥颗粒之间的摩擦力,提高混凝土的流动性。而且其比表面积大,表面能高,吸附水的能力小。但是Ⅱ级以下的粉煤灰(如散灰等),含有较多的多孔玻璃微珠或含碳量较高,会增加混凝土的需水量。
