摘要：通过凝结时间、水化温度、XRD、SEM、抗压强度试验等研究了纳米C-S-H早强剂对水泥水化及混凝土强度的影响，并分析了作用机理。结果表明：纳米C-S-H早强剂明显缩短了水泥的凝结时间；随着纳米C-S-H早强剂掺量的增加，水化温度峰出现时间缩短，且峰值提高；掺入适量的纳米C-S-H早强剂不改变水泥的水化产物种类，但加速了水泥水化进程，提高了混凝土的早期抗压强度，且后期（28 d、56 d）抗压强度无倒缩。 Abstract: The influence of nano C-S-H early strength agent on cement hydration and concrete strength was studied through setting time, hydration temperature, XRD, SEM, and compressive strength tests, and the mechanism of the action was analyzed. The results show that the nano C-S-H early strength agent significantly shortens the setting time of cement. With the increase of the content of nano C-S-H early strength agent, the time for the hydration temperature peak to appear is shortened, and the temperature peak increases. The suitable addition of nano C-S-H early strength agent does not change the type of hydration products in cement, but accelerates the cement hydration process, improves the early compressive strength of concrete, and there is no shrinkage in the later(28 d、56 d) compressive strength.
