含高铝水泥的砂浆和砼的强度是温度的函数,它随着水化铝酸盐由六方晶系向立方晶系转变而迅速下降。可以通过改变混和料的pH值来调整水化铝酸盐在硬化产物中的比例。由已发表的文献可知:当加入铝酸钙时,溶液的pH值升高,水化过程加速,六方晶系的水化铝酸钙向立方晶系的水化铝酸钙的转变加剧,结果导致强度损失。Krivenko等人证明:用铅酸钙和硅酸钠可生产具有稳定热机性能的砼。其他研究者证明:提高溶液的pH值会抑制水
The strength of mortars and crucibles containing high-aluminum cement is a function of temperature, and it rapidly decreases as the hydrated aluminate transitions from a hexagonal system to a cubic system. The proportion of hydrated aluminates in the hardened product can be adjusted by changing the pH of the mixture. It is known from the published literature that when calcium aluminate is added, the pH of the solution is increased and the hydration process is accelerated, and the transformation of the hexagonal calcium aluminate hydrate to the cubic hydrated calcium aluminate increases. Causes loss of strength. Krivenko et al. demonstrated that using lead calcium and sodium silicate can produce helium with stable thermomechanical properties. Other researchers have demonstrated that increasing the pH of a solution inhibits water
