近年来在水泥工业生产和水泥实际使用中,水泥颗粒级配问题似乎引起了人们的关注。许多资料表明:水泥颗粒级配不仅影响粉磨工艺过程的能耗,还明显地影响水泥的使用性能(例如:浆体的和易性、混凝土的强度发展等)。因此,从改善粉磨工艺降低电耗、提高水泥的使用性能、尽快地发挥混凝土的强度加速施工进度等实际问题出发,在理论和实验上研究颗粒级配之影响是颇有意义的。意大利学者G.Frigione和S.Marya曾于1976年报道过他们在水泥颗粒级配对水泥水化速度、浆体强度发展等方面影响的研究工作。他们从理论上证明水泥颗粒级配愈窄水泥水化速度愈快,从而水化生成物愈多。并且根据T. C. Powers强度理论推论:相应
In recent years, in cement industry production and actual use of cement, the problem of cement particle gradation seems to have attracted people’s attention. Many data indicate that the gradation of cement particles not only affects the energy consumption during the grinding process, but also significantly affects the performance of the cement (for example, the workability of the slurry, the strength development of the concrete, etc.). Therefore, starting from the practical problems of improving the grinding process, reducing electricity consumption, improving the performance of cement, accelerating the construction of concrete as quickly as possible, and accelerating the construction schedule, it is of great significance to study the effects of particle size distribution theoretically and experimentally. Italian scholars G. Frigione and S. Marya once reported in 1976 their research on the effect of cement particles on the hydration speed of cement and the development of slurry strength. They theoretically prove that the narrower the cement particle size distribution is, the faster the hydration rate of cement is, and the more hydration products are. And according to the T. C. Powers intensity theory,
