磺化煤焦油减水剂是煤焦油经硫酸磺化烧碱中和而制成的磺酸盐,对水泥颗粒具有明显的分散性和吸附作用,掺入混凝土中,在保持强度和坍落度不变的情况下可以减少单位用水量10%,节约水泥10%。在保持水灰比不变的情况下,可增大坍落度7厘米左右,并能提高混凝士的早期强度。磺化煤焦油具有以下的优点:原材料来源于我省丰富的炼焦付产品—煤焦油;工 Sulfonated coal tar water-reducing agent is a sulfonate produced by the neutralization of coal tar by sulfuric acid sulphonating caustic soda. It has obvious dispersion and adsorption effect on cement particles. It is incorporated into concrete and does not maintain strength and slump. In case of change, the unit water consumption can be reduced by 10%, and cement can be saved by 10%. With the same water-cement ratio, the slump can be increased by about 7 cm, and the early strength of the fortifiers can be improved. Sulfonated coal tar has the following advantages: raw materials come from our province’s abundant coking products - coal tar;
