【 摘 要 】

In this paper, it studies the effect of the water-cement ratio, fly ash, PP fiber and high-performance expansion agent on the mechanical property and contractility of the foam concrete through experiments. The results of the experiment show that in the middle-late stages of hydration, the foam concrete shows the characteristic of contraction; when the water-cement ratio is between 0.3 to 0.5, the greater the ratio is, the smaller the contraction of foam concrete will be; when the water-cement ratio is greater than 0.5 or less than 0.2, the contraction amount of 28 d decreases. Fibers in random distribution may slightly reduce the shrinkage of foam concrete; while a certain content of expander can effectively compensate for the deformation shrinkage of foam concrete, and even realize no shrinkage in the early stage of hydration.
