Abstract

The invention discloses aluminate cement and a preparation method thereof, and relates to the field of building materials. The aluminate cement comprises the following components in percentage by mass: (1) 55.0%-75.0% of aluminate cement clinker, (2) 3.0%-10.0% of barium slag, (3) 5.0%-15.0% of garnierite tailings, (4) 5.0%-15.0% of red mud, (5) 3.0%-10.0% of steel slag, and (6) 2.5%-5.0% of gypsum, wherein the content of aluminium oxide in the aluminate cement clinker is 47.0%-65.0%. The preparation method of the aluminate cement comprises the following steps: (1) preparing materials, (2) grinding, and (3) pulverizing. The aluminate cement has the characteristics of being high in hardening rate and high in hardening strength, and besides, effectively overcomes the defect that the long-term strength of the conventional aluminate cement is relatively low, and effectively uses various industrial wastes, and is a very ideal cement material.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an aluminate cement and a preparation method of the cement. Background technique [0002] Aluminate cement is a hydraulic cementitious material made of bauxite and limestone as raw materials, calcined clinker with calcium aluminate as the main component and alumina content of about 50%, and then finely ground. Aluminate cement is often yellow or brown, but also gray. The main minerals of aluminate cement are monocalcium aluminate and other aluminates, as well as a small amount of dicalcium silicate. [0003] Aluminate cement has fast setting and hardening speed, large cement hydration heat and concentrated heat release. It is mainly used in projects with urgent construction schedules. Even if it is constructed at -10°C, aluminate cement can quickly set and harden. It can be used Construction works in winter. Under ordinary hardening conditions, aluminate cement has a strong r...
