Description

(1) Technical field

[0001] The invention belongs to the technical field of cement materials, in particular to an alite-barium calcium sulfoaluminate cement compounded with barium calcium sulfoaluminate mineral and alite mineral. (2) Background technology

[0002] At present, Portland cement used in large quantities has some shortcomings and deficiencies, mainly manifested in high firing temperature (1450°C), low early strength and long setting time, resulting in high energy consumption for cement manufacturing and increased production costs. It has a certain influence on the construction speed and construction quality. Therefore, how to further reduce the firing temperature of Portland cement and improve its early performance is a key problem in the field of cement technology.

[0003] For example, the Chinese patent "barium-containing sulfoaluminate cement" published on September 13, 1989 with the publication number CN1035486A is a fast-hardening and early-strength cement ...
