Preparation method for phosphorus-based high-flowability lightweight thermal-insulation wall material
A disclosed preparation method for a phosphorus-based high-flowability lightweight thermal-insulation wall material comprises putting 10%-20% by weight of shale ceramisite in water and pre-wetting for 35-50min; uniformly mixing 6%-10% by mass of dihydrate phospho gypsum, 50%-70% by mass of phosphorus slag powder and 5%-15% by mass of fly ash with ceramsite to obtain a mixture; adding water into the mixture, 4%-8% by weight of an alkali activator, 0.8%-1.5% by weight of a water reducer and 0.1%-0.2% by weight of a water-retaining agent, controlling the water-material ratio to be 0.33-0.38, and mixing with stirring in a material homogenization machine to prepare a slurry, so as to obtain the phosphorus-based high-flowability lightweight thermal-insulation wall material. The material possesses the slump of 270 mm or more, the slump flow of 650 mm or more, the initial setting time of 45 min or more, and the final setting time of 240 min or less. The wall material dry density of 1000 kg/m<3> or less, the 28 day compressive strength of 5 MPa or more, and the heat-conduction coefficient of 0.23 W/(m*K) or less. On-site pouring molding is employed, and construction speed is fast. The material is applicable to fill internal and external walls.
