Abstract
The effects of initial temperature and water to material ratio on hydration heat of Autoclaved Aerated Concrete (AAC) slurry were studied. The effects of curing temperature and mold conditions on the temperature field of the green cake during the setting process were analyzed. The temperature distribution green cake was tested and simulated by finite element software. The results show that the higher the initial temperature, the higher the rate of hydration heat, but does not affect the total hydration heat of slurry. When the water to material ratio increases, the maximum temperature rises of slurry decreases. When the curing temperature of the green cake increases, the temperature field remains unchanged, the maximum temperature rises increases, and the temperature difference in the same dimension decreases. The size and distribution of the temperature in the height direction is affected by the mold conditions on the upper surface of the green cake, while the temperature in the radius direction is affected by the mold conditions on the side of the green cake, but the distribution law remains unchanged. The finite element model of temperature field of green cake in the setting process of AAC is established and has good accuracy with the test values.
