本文研究了不同熟料组成的粉煤灰水泥水化3天、7天和28天硬化浆体的ζ电位、非蒸发水(Wn)、电导率(λ)、浆体悬浮液的pH值和试体的强度,并用TG热分析估算了浆体中Ca(OH)_2含量;同时讨论了粉煤灰水泥硬化浆体的物理化学性能与水化时间的关系,以及硬化浆体中粉煤灰的火山灰活性。 In this paper, the zeta potentials, non-vaporized water (Wn), conductivity (λ), and slurry suspension pH of three-day, seven-day and twenty-eight day hardened fly ash cements with different clinker contents were studied. The strength of the test specimens and the TG thermal analysis were used to estimate the Ca(OH) 2 content in the slurry. The relationship between the physical and chemical properties of the hardened fly ash cement paste and the hydration time and the fly ash in the hardened slurry were also discussed. Pozzolanic activity.
