一、安定性不合格水泥的存在近几年来,我们共检水泥2910组,主要是安徽省宿州市各建设工地送检的矿渣水泥、普通水泥、复合水泥共3个品种、7个强度等级,对安定性检验结果进行统计,发现有253组水泥的安定性不合格,占8.7%,冬季小水泥安定性不合格较多,最高的一个冬季高达16.2%。这些安定性不合格的水泥应怎样处理呢?一般是存放一段时间,待转化为合格后再用。二、影响水泥安定性的主要因素影响水泥安定性的主要因素有 MgO、SO_3和 fCaO(游离氧化钙)。因生产过程中严
First, the stability of substandard cement the presence of In recent years, we seized 2910 groups of cement, mainly in Suzhou City, Anhui Province construction site inspection of slag cement, ordinary cement, composite cement a total of three varieties, seven intensity levels, Statistics on the stability test results showed that 253 sets of cement failed in stability, accounting for 8.7%. In winter, the stability of small cement was more unqualified, with the highest one being as high as 16.2% in one winter. These stability of cement should be how to deal with it? Is generally stored for some time, to be converted into qualified and then used. Second, the main factors affecting the stability of cement Cement stability affecting the main factors are MgO, SO_3 and fCaO (free calcium oxide). Due to strict production process
