摘    要:通过测试各混合水泥试样结合水量和掺合料反应程度.研究了不同养护制度对混合水泥水化程度的影响。研究结果表明,早期较高的养护温度可加快混合水泥的反应速率,提高其反应程度.但对后期标养条件下混合水泥反应程度的增长有影响;早期低温养护情况下混合水泥的水化受到抑制。其反应程度相当低,但后期标养条件下有一定增长。养护温度升高有利于混合水泥中掺合料反应程度的提高.但在后期长时间标养条件下,奇试样中掺合料反应程度趋于接近。

关 键 词:养护制度  混合水泥  反应程度

Abstract:The non-evaporable water content of blended cement specimens and the reaction degree of mineral admixtures were tested to study the effect of different curing regimes on the hydration of blended cement. The results showed that, the higher temperature in earlier curing stage could accelerate the reaction speed of blended cement and increase the reaction degree, but it would affect the increase of reaction degree in later standard curing stage. The hydration of blended cement was retarded in low-tenperature curing stage,but the reaction degree could still increase in later standard curing stage. The higher curing temperature was benefit for the increase of the reaction degree of mineral mixtures, however, the reaction degree of specimens in different curing regimes were tend to get closer.
Keywords:Curing Regimes  Blended Cement  Reaction Degree
