RAPID-SETTING AND HARDENING HIGH-BELITE SULFOALUMINATE CEMENT CLINKER AS WELL AS APPLICATION AND PRODUCTION PROCESS THEREOF

摘要

[0001] The present invention relates to a rapid acylated high-bellite sulfoaluminate cement clinker, and more particularly, to a rapid acylated high-bellite sulfoaluminate cement clinker and a method of making and using the clinker. The clinker of the present invention comprises 20% to 35% by weight of C ₄ A ₃ , From 3 wt% to 9 wt% of C ₄ AF, from 37 wt% to 47 wt% of C ₂ S, from 0.5 wt% to 4.6 wt% of f-CaO, and from 14 wt% to 26.3 wt% of CaSO ₄ do. The chemical composition of the clinker is 12.9 wt% to 16.1 wt% SiO ₂ , 12 wt% to 19 wt% Al ₂ O ₃ , 1 wt% to 3 wt% Fe ₂ O ₃ , 49 wt% to 54 wt% CaO, and 12 wt% to 18.43 wt% SO ₃ . The clinker comprises a meal comprising 33 wt% to 62 wt% limestone, 10.5 wt% to 28 wt% fly ash, and 19 wt% to 45 wt% FGD gypsum in a rotary kiln at 1300 賊 50 캜 / RTI The steep, high strength cement groups of varying strength grades are blended with 26 wt% to 97 wt% clinker, 3 wt% to 19 wt% pumice, and 0 wt% to 55 wt% granulated blast furnace slag And pulverizing.
