▎ 摘  要

NOVELTY - Rapid preparation of alkali-free, chlorine-free and steam-free concrete admixture involves adding 0.5-1.5 %mass carbon collector, 5-10 %mass lithium silicate, 1-3 %mass crystalline bottom plate component, 0.1-0.3 %mass waterproof component, 0.05-0.15 %mass crystal inducer and remaining deionized water to an emulsifier with cooling cycle, emulsifying at 0-30degrees Celsius and 6000-8000 rpm for 1-2 minutes, adding 8-13 %mass crystalline component after each component is dissolved, emulsifying for 2-5 minutes, adding 1-4 %mass cation stabilizer, emulsifying for 2-5 minutes, and introducing carbon dioxide gas into obtained mixture at a flow rate of 200-400 mL/minute for 10-20 minutes. USE - Preparation of concrete admixture used for preparing prefabricated component e.g. wallboard, balcony, duct component and beam. ADVANTAGE - The method has short preparation time, low carbon discharge, simple method and consumes carbon dioxide. The additive has no alkali and chlorine, the stability is good, it is suitable for the concrete label. The prefabricated component concrete has proper viscosity, good durability, no steam pressure reducing energy consumption cost and good disassembly appearance performance.
