摘要： Provided are a shrinkage-reducing agent for a hydraulic material and a shrinkage-reducing agent composition for a hydraulic material each having high general-purpose property. Each of the agent and the composition does not require a combination with any other admixture, is inexpensive, suppresses a reduction in strength of a cured article, suppresses the generation of a crack in a cured concrete body by virtue of its excellent shrinkage-reducing function, and shows such good compatibility with a water-reducing agent as to impart an excellent water-reducing function. Further, each of the agent and the composition can improve the quality of entrained air with an antifoaming agent and an AE agent so easily as to be capable of imparting excellent freezing-thawing resistance to the cured concrete body to improve the durability of the cured concrete body. The shrinkage-reducing agent for a hydraulic material of the present invention includes a compound represented by the general formula (1): R 1 -[O-(A 1 O) m -R 2 ] n (1), where: R 1 represents R 1 derived from a polyhydric alcohol represented by R 1 -[OH] n ; A 1 O represents an oxyalkylene group having 2 to 18 carbon atoms; R 2 represents a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms; m represents an average addedmole number of oxyalkylene groups A 1 O's; n represents 3 or 4; and when n equals 3, m represents 30 to 150, and when n equals 4, m represents 5 to 150.

摘要： Lime-free admixture compositions comprise a combination of emulsifiers, toughening resins/plasticizers, adhesive resins, pumping aids for providing lubrication, rheology controllers, water retention agents, water repellents/overcoat finishes, accelerators, water reducers and air entraining agents. The lime-free admixture compositions are total replacements for lime. The lime-free admixture compositions are non-corrosive, making them safe to use by workers and they have rheological properties that make them suitable for use in various applications including concrete, mortars, grouts and stuccos (renders).

摘要： The invention relates to a method and system for monitoring and adjusting both air content and rheology (e.g., slump, slump flow) properties of a hydratable concrete mix contained within a concrete mixer. The system simultaneously tracks dosage of both rheology-modifying admixture (e.g., polycarboxylate polymer cement dispersant) and air control agent or "ACA" (e.g., air entraining agent) by reference to at least four nominal dose response ("NDR") curves or profiles, which at least four NDR profiles are based on the respective behaviors of each of the ACA and rheology-modifying agent on air content and rheology.
