摘　　要：通过对水泥-石灰-粉煤灰干硬性体系进行单纯型-格子研究,探讨了石灰掺量对该体系早期与后期无侧限抗压强度的影响规律.结果显示:石灰掺量对水泥-石灰-粉煤灰干硬性体系早期强度的影响规律与其中的水泥掺量有关,当水泥掺量低于7%(质量分数,下同)时,掺入石灰有助于体系早期强度的提高;当水泥掺量高于7%后,掺入石灰对该体系早期强度反而存在负面作用;不论水泥掺量如何,掺入石灰均能提高该体系的后期强度.Aiming at the problem that influences the lime dosage on the strength of the cement-lime-fly ash,the cement-lime-fly ash stiff system was researched by simple-lattice designing and influences of lime on the different age＇s strengths were discussed.It is proved that there is a relationship between the influence rules of lime on the early strength of this system and cement content,the lime has feeble active effect on early strength of system when the content of cement is below to 7%（by mass） and that lime has negative effect on it when the content of cement is up to 7%.However,the lime can improve long-term strength of system no matter how much the cement content is.
