采用化学结合水含量法和水化热法研究了不同粉煤灰掺量、不同养护温度、不同含水率下粉煤灰-水泥复合材料（FA-C）的整体水化程度。通过水化产物的解耦分析，得到了粉煤灰-水泥复合膏体在理论水化作用下的化学结合水含量。结合Knudsen方程线性萃取，通过提高熟化温度来加速FA-C的反应，得到了更理想的FA-C全水化热。FA-C的整体水化程度随着粉煤灰掺量、养护温度和水比的升高而增大。
The chemical combined water content method and the hydration heat method were used to study the integral hydration degree of fly ash-cement compounds(namely FA-C)with different amount of fly ash,different curing temperatures and variable water ratios.Through decoupling analysis of hydration products,we got the chemically combined water content of fly ash-cement compound pastes under the theoretical hydration.Combined with linear extraction by Knudsen equation,we got a more ideally entirely hydration heat of FA-C through improving the curing temperature to accelerate the reaction of FA-C.The integral hydration degree of FA-C increases with the rising of content of fly ash,the curing temperature and the water ratio.
