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...
