Core-shell structure light high-performance unfired ceramsite as well as preparation method and application thereof
The invention provides light high-performance unfired ceramsite with a core-shell structure as well as a preparation method and application of the light high-performance unfired ceramsite. The method comprises the following steps: preparing modified natural lightweight aggregate; weighing raw materials for preparing the unfired ceramsite shell layer; mixing ardealite, fly ash, slag powder and quick lime to obtain shell layer raw material mixed powder; transferring part of the shell layer raw material mixed powder to be used and all the modified natural light aggregate into a granulator for stirring; spraying water and a foaming binder into the granulator at a constant speed, and continuously adding the residual standby shell layer raw material mixed powder into the granulator during the period until the surface of the modified natural light aggregate is uniformly coated with a layer of shell material, so as to obtain the spherical unfired ceramsite with a core-shell structure; and transferring the spherical unfired ceramsite into a standard curing box for curing to obtain the lightweight high-performance unfired ceramsite with the core-shell structure. The ceramsite does not need to be sintered, is energy-saving and environment-friendly, and has the characteristics of light weight, high strength, heat preservation and heat insulation.
本公开提供了一种核壳结构轻质高性能免烧陶粒及其制备方法和应用。该方法包括：制备改性天然轻集料；称取用于制备免烧陶粒壳层的原材料；将磷石膏、粉煤灰、矿渣粉和生石灰进行混合，得到壳层原材料混合粉末；将部分的待用壳层原材料混合粉末与全部改性天然轻集料移至造粒机中进行搅拌；将水和发泡粘结剂匀速喷入造粒机中，在此期间持续向造粒机中加入剩余的待用壳层原材料混合粉末，直至改性天然轻集料表面均匀包裹一层壳料，得到具有核壳结构的球形免烧陶粒；将球形免烧陶粒移至标准养护箱内养护，得到核壳结构的轻质高性能免烧陶粒。本公开的陶粒无需烧结，节能环保，具有轻质高强、保温隔热的特点。
