Abstract : based on composite testing of naphthalene superplasticizer and different retarders as well as retarding water reducer, in which the overall amount of admixture is certain, this paper analyzes the influence of these multicomponent admixtures on flowability of neat cement 、 retarding action and development of strength of colloidal mortar. the result shows that compatibilities of different components are different, and composition effects are also different
