The invention relates to an assembly type building component joint gypsum base sealing material and application thereof. The assembly type building component joint gypsum base sealing material comprises, by weight, 100 parts of waste gypsum, 20-200 parts of active admixture, 0.01-10 parts of water reducer, 0.1-50 parts of excitant, 0-10 parts of thickening control agent, 0-30 parts of binder, 0-10 parts of air entraining agent, 0.01-30 parts of plastic retaining agent, 0.01-10 parts of water repellent, 0-5 parts of starch ether, 0-10 parts of thixotropic lubricant, 0-150 parts of powder filler and 0-300 parts of aggregate, and can be applied to joint sealing after being mixed with water uniformly. Compared with the prior art, the assembly type building component joint gypsum base sealing material has the advantages of convenience in use, good filling ability, high binding power, durability, low cost and the like. In the sealing material, much industrial waste gypsum is used as gelatinization materials, so that performance of sealing mortar can be improved, material cost is reduced, pollution control and emission reduction are facilitated, and a new way for resource utilization of the industrial waste gypsum is provided. |
