Lightweight thermal insulation foam concrete and preparation method thereof
The invention discloses lightweight thermal-insulation foam concrete and a preparation method thereof, and relates to the technical field of concrete materials, the lightweight thermal-insulation foam concrete meets the requirements of different projects on concrete performance through cement proportioning, combination of lightweight aggregate and additional lightweight aggregate and introduction of an optimization auxiliary agent, the fluidity of concrete is optimized by applying a rheology principle, and the thermal-insulation performance of the concrete is improved. The high-efficiency water reducing agent, the foaming agent and the microsphere stabilizer are introduced, so that the flowability of the concrete is effectively improved, the construction is more convenient, and in terms of compressive strength, Portland cement, calcium magnesium phosphate cement and calcium silicate cement with compressive strength of 42.5 or above are selected as base materials, and are matched with lightweight aggregate and optimized auxiliaries, so that the crack resistance and durability of the concrete are effectively improved; besides, expanded and vitrified microbeads of 75-95 microns and foam glass particles are used as main lightweight aggregates, and additional lightweight aggregates including aerogel particles, polyphenyl particles, diatomite particles and ceramic particles are introduced, so that the heat insulation performance of the concrete is effectively improved, and the heat preservation effect is more remarkable.
