摘要
通过试验 ,研究了组成三峡二期工程混凝土的各种原材料的变化及不同的成型工艺等因素对混凝土表面气泡数量的影响。试验结果表明 ,对混凝土表面气泡影响最大的因素是减水剂 ,粉煤灰其次 ,而引气剂的影响不明显 ,其它因素也有一定的影响。试验成果为消除混凝士表面气泡提供了理论依据。
Experimental studies on influences of different materials and casting technologies on surface air bubbles of concretes for Three Gorges Project(TGP) were conducted.The results demonstrate that water reducer is dominant effective factor,fly ash exhibitions a little comparable effect,and effect of air-entrained agent is not much obvious as known.
