摘要
本文研究了三乙醇胺、糖蜜以及两者复合对水泥早期强度的影响,研究发现三乙醇胺在一定掺量范围内有较好的早期增强效果,糖蜜则有微弱的增强效果,但两者复合效应较为明显。其原因可能是三乙醇胺加快了水在水泥颗粒内部的渗透,促进了水泥矿物相的水解,而糖蜜的吸附作用使得水化产物形成相对密实的结构,两者效果互为作用,从而增强效果明显。
The influence of molasses, TEA and the combination on the early age strength of cement paste is studied. It is found that TEA at certain dosage can enhance the early age strength of cement paste rapidly, and the improvement of molasses is slight, but the improvement of the combination is significant. The reason might be that TEA can increase the penetration of water into cement particles and accelerate the hydration of cement mineral phase, and the absorption effect of molasses makes the hydrated products denser, and the two kinds of effect work together.
