Gypsum-based cementing material
The invention discloses a gypsum-based cementing material. The gypsum-based cementing material comprises blast-furnace slag powder, a gypsum mixture, an active admixture, an alkali-activator, a coagulation accelerator, lime, a water-reducing agent and an early-strength admixture. According to the gypsum-based cementing material, sulphoaluminate cement, portland cement and gypsum are mixed at a certain proportion to react so as to generate ettringite with expansion characteristic, so that the gypsum-based cementing material has the characteristics of being quick in setting and hardening and low in shrinkage ratio, and therefore, can be used for preparing various quick-hardening mortars aiming at shortening the construction period and quickening delivery and service. The gypsum-based cementing material is early and high in strength, low in shrinkage ratio, wide in source and low in production cost and has the functions of environmental protection and carbon emission reduction.
