The influence of organic agents on the chemical activation of blast furnace slag is revealed due to studying of the physical-mechanical properties of the blended cement with modified slag. Complex waterproofing admixtures based on diethanolamide and oleic acid is used as the organic agents. Utilization of the optimal concentration of the agents leads to the increasing of the hydraulicity of the blast furnace slag resulting in the accelerating of the blended cement hardening. In addition the organic agents decrease water adsorption resulting in the increasing of the storage life. The complex waterproofing admixtures can be utilized as chemical admixtures in the building materials industry.
