泵送粉煤灰混凝土的抗冻性能

Frost resistance property of pump flyash concrete

通过试验 ,研究了等量及超量取代法配制的掺粉煤灰混凝土在负温养护下的强度发展规律及抗冻性 ,表明双掺粉煤灰和高效防冻剂可以使负温混凝土具有良好的强度和优异的耐久性 。

In this paper the development regularity of strength and frost resistance property under negative temperature maintenance of flyash concrete are studied, which made by equivalent or excessive replacement technology. The study show that fill flyash and high efficacy antifreeze can made the negative temperature concrete with good strength and durability to meet the demands of winter construction.
