Unfired ceramsite and preparation method thereof
The invention discloses unfired ceramsite and a preparation method thereof, and belongs to the technical field of building materials. The unfired ceramsite is prepared from the following raw materials in parts by mass: 20 to 50 parts of limestone powder, 50 to 80 parts of industrial byproduct gypsum, 0.1 to 0.4 part of gypsum retarder, 0.5 to 1.75 parts of acid and 25 to 35 parts of water. The preparation method comprises the following steps: S1, uniformly mixing the limestone powder, the industrial byproduct gypsum and the gypsum retarder to obtain mixed powder; s2, adding acid into water, and uniformly mixing to obtain an acid solution; s3, adding an acid solution into the mixed powder, uniformly stirring, and granulating to obtain spherical particles; s4, maintaining the spherical particles for 1 day; and S5, drying the cured spherical particles to obtain the product. The method can synergistically solve the problem of low utilization rate of limestone powder and industrial byproduct gypsum, realizes reutilization of solid waste resources, innovates a resource utilization approach, and improves the additional value of the resources.
本发明公开了一种免烧陶粒及其制备方法，属于建筑材料技术领域。免烧陶粒包括以下质量份的原料：石灰石粉20～50份，工业副产石膏50～80份，石膏缓凝剂0.1～0.4份，酸0.5～1.75份和水25～35份。其制备方法如下：S1：将石灰石粉、工业副产石膏和石膏缓凝剂混合均匀，得混合粉体；S2：将酸加入水中混合均匀，得酸液；S3：将酸液加入到混合粉体中，拌匀后造粒，得球形颗粒；S4：将球形颗粒养护1天；S5：将养护后的球形颗粒进行干燥，即得。可协同解决石灰石粉和工业副产石膏利用率不高的问题，实现固废资源的再利用，创新资源利用途径，提高资源的附加值。
