Abstract

The invention discloses calcium sulphoaluminate-Relit composite mineral phase cement and preparing method, which is characterized by the following: adopting coal ash, alumina, limestone and plaster as raw material and fluorite as mineralizer; designing MG and MS value; introducing new Relit mineral in the preparing course of common aluminium sulfate cement; preparing new clinker of new calcium sulphoaluminate-Relit composite mineral phase cement under 1200-1330 deg.c with 45%-65% C4A3S, 20%-36% C3S and residual C2S.

Description

technical field [0001] The invention belongs to the technical field of cement materials and relates to the preparation of novel calcium sulfoaluminate-alite composite mineral phase cement clinker with fly ash as the main raw material. Background technique [0002] Calcium sulfoaluminate and alite are the main mineral phases of ordinary sulfoaluminate cement and Portland cement, respectively. Calcium sulfoaluminate has good gelling properties and fast hydration speed, and is a typical early-strength mineral, but the later-stage strength growth rate is low; Alite mineral is also a mineral with excellent gelling properties, which is the strength of Portland cement. The main source, but the early strength is low, and the late strength increase rate is high. Therefore, realizing the combination of these two main minerals in sulfoaluminate cement and Portland cement to prepare a new type of calcium sulfoaluminate-alite composite mineral phase cement can further improve the mechan...
