很高兴应《商品混凝土》杂志之邀在贵刊第三期“特别策划”栏目中谈谈混凝土配合比设计中的“水灰比定则”问题,也就是混凝土的抗压强度与所用水灰比之间的关系问题,即混凝土科研界和工程界普遍关心的水胶比公式问题。这个问题一直困扰着混凝土工程界并为此争论不休,因为区别于传统混凝土材料组成,现代混凝土组成材料中普遍使用化学外加剂,尤其是高效减水剂或高性能减水剂和矿物掺合料。为了弄清楚在混凝土拌合物中掺入减水剂以后,水胶比公式是否还可用来计算混凝土水胶比的问题,或者说现代混凝土配合比设计中是否还可以采用保罗米(Bolomy)水灰比公式确定水灰比的问题,本文谈一谈我个人的观点,供广大混凝土科研人员和工程技术人员参考。
It is my pleasure to discuss the issue of “water-cement ratio rule” in concrete mix design in the 3rd issue of “Special Planning” of your magazine with the publication of “Concrete for Concrete”, that is, the compressive strength of concrete And the water-cement ratio used in the relationship between the problem that the concrete research community and engineering community generally concerned about the water-cement ratio formula. This problem has plagued the concrete engineering community and has been debated endlessly because different from traditional concrete materials, modern concrete components commonly used chemical admixtures, especially superplasticizers or superplasticizers and mineral admixtures . In order to find out whether the water-cement ratio formula can be used to calculate the concrete water-cement ratio after admixture of water-reducing admixtures in concrete mixes, or whether the design of modern concrete can use Bolomy water Ash than the formula to determine the water-cement ratio problem, this article talk about my own point of view for the majority of concrete researchers and engineering and technical personnel for reference.
