【 摘 要 】

Strong hygroscopic of sodium silicate sand is a key problem in the practical application. Hygroscopic mechanism research of sodium silicate sand is not enough. CO2 hardened and microwave heating hardened to composite hardened process of sodium silicate sand has been proposed in this paper. Through optimization of air temperature, blowing time, microwave power and heating time, get the best resistance to moisture absorption process parameters of composite hardened sodium silicate sand. The process and the mechanism of moisture absorption were analyzed for composite hardened sodium silicate sand. The influence factor of moisture absorption was made clear. Laid a preliminary foundation to solve the problem of sodium silicate sand strong hygroscopic.
