摘要

本文研究了水泥窑旁道粉尘对硅酸盐水泥和矿渣水泥性能的影响。实验采用的参考水泥为CEM I 42.5R和CEM III/A 42.5N。水泥窑旁道粉尘置换量分别为0.7%和1.7%，满足水泥中Cl-离子含量≤0.1%，符合PN-EN 197-1:2012标准要求。考察了水泥的以下性能:水化热、正常稠度需水量、初凝时间和抗压强度。结果表明:水泥窑旁道粉尘掺量不超过1.7%，对硅酸盐水泥和矿渣水泥的性能没有负面影响;胶结物与未添加粉尘的胶结物具有相同的强度等级。

The influence of cement kiln by-pass dust addition on the properties of Portland and slag cement

In this paper, the infl uence of cement kiln by-pass dust on the properties of Portland cement and slag cement was studied. The reference cements used in the experiment were CEM I 42.5R and CEM III/A 42.5N. The cement kiln by-pass dust replacement of cement was 0.7% and 1.7%, to satisfy the Cl- ions content in cements: lower than or equal to 0.1%, following the demand of PN-EN 197-1:2012 standard. The following properties of cements were examined: the heat of hydration, water demand for normal consistency, initial setting time and compressive strength. The results showed that the addition of cement kiln by-pass dust of up to 1.7% has no negative effect on the properties of Portland cement and slag cement. The cements represent the same strength class, as without dust addition.
