细度适宜的某些矿物微粉具有强烈的减水作用，而且这种减水作用可以在化学减水刑 （超塑化剂）无能为力的超低水灰比条件下发挥出来，因而在ＵＨＰＣ的制备中具有重要作用。由 此，本文提出了混凝土矿物减水剂的概念，并研究了矿物减水刑的机理、模型和参数。在此基础 上，研制了一些具有强烈减水作用的矿物微粉，利用这些矿物微粉以及广州地区容易获得的其他 原材料，稳定地制备了坍落度大于１７ｃｍ、２８天强度达１００－１２８ＭＰａ的超高性能混凝土。
Some fine powders of fineness have a strong water-reducing effect, and this water-reducing effect can be exerted under the helpless condition of super-low water-cement ratio by chemical water-reducing method (superplasticizer) In the important role. Therefore, this paper presents the concept of concrete mineral water-reducing agent, and studies the mechanism, model and parameters of mineral water-reducing punishment. On the basis of this, a series of mineral micropowders with strong water-reducing effect have been developed. With these mineral micropowders and other raw materials easily available in Guangzhou, we can steadily prepare super-high slump with a slump of more than 17cm and a strength of 100-128MPa at 28 days Performance concrete.
