本文通过分析收尘石灰石粉的性质,提出了收尘石灰石粉在预拌混凝土中的应用方法,即:将收尘石灰石粉作为混凝土生产原材料,其中粉末部分作掺合料等量替代粉煤灰,细砂部分则等量替代特细砂使用,收尘石灰石粉的有效掺量以粉末掺量计。然后,试验测定了收尘石灰石粉混凝土的性能,结果表明:与同等级粉煤灰混凝土比较,收尘石灰石粉混凝土的工作性能相当,强度发展较快,但该混凝土干燥收缩略大。 In this paper, by analyzing the nature of dust collection limestone powder, put forward dust collection limestone powder in ready-mixed concrete application method, namely: dust collection limestone powder as raw material for concrete production, in which the powder part of the admixture equivalent to replace fly ash , Fine sand part of the same amount of fine sand to replace the use of dust collection effective dosage of lime powder to powder content. Then, the performance of the limestone dust-receiving concrete was tested. The results show that compared with the same grade fly ash concrete, the performance of the lime-lime-dusting concrete is similar, the strength develops rapidly, but the concrete shrinkage slightly.
