Abstract: In order to calculate quickly the degree of reaction of mineral admixtures in composite cementitious material pastes, the degrees of reaction of mineral admixtures in the saturated limewater with sodium hydroxide (NaOH) and composite cementitious material pastes were measured by the selective solvent dissolution, whose corresponding relationship was also established .The results indicate that the degree of reaction of mineral admixtures in the saturated limewater with NaOH which is combined with the water-binder ratio and the content of mineral admixtures can predict that of mineral admixtures in composite cementitious material pastes , which is with the accuracy and reliability .
