众所周知,水泥中加入外加剂,甚至是低稠(密)度外加剂可以提高它的初期强度。硫代硫酸钠可提高硅酸三钙的水化速度,而加入丙三醇、三乙醇胺和丁醇可提高结晶新生体的强度。除采用化学方法外,人们还研制出了借助超声波、磁场等控制水化的物理方法。这样水泥颗粒原有的水化层被破坏,有更大的表面积参加水化过程。采用超声波能够提高水泥初期 It is well known that adding an admixture to the cement, even a low-viscosity admixture, can increase its initial strength. Sodium thiosulfate can increase the hydration rate of tricalcium silicate, while the addition of glycerol, triethanolamine and butanol can increase the strength of the crystallized neosome. In addition to using chemical methods, people have also developed physical methods for controlling hydration with the aid of ultrasonic waves, magnetic fields, and the like. In this way, the original hydration layer of the cement particles is destroyed, and a larger surface area participates in the hydration process. Ultrasound can improve the early stage of cement
