Preparation of magnesium silicate bainite calcium aluminate cement

摘要

The invention relates to a method for preparing adhesive, which comprises the following steps: (a) providing raw materials with Ca + Mg molar ratio of 1.0-3.5 mg / S (+ AI + Fe), 0.1-100 mg molar ratio and 100-0.1 ml molar ratio. 1. Do not consider the components that are inert in high-pressure heat treatment;(b) Raw material mixture;(c) At the temperature of 100 ℃ to 300 ℃, the mixture of raw materials produced in autoclave is treated by hydrothermal method, the residence time is 0.1-24 hours, and the ratio of water to solid is 0.1-100;(d) The annealing temperature of the intermediate product obtained in step (c) is between 350 ℃ and 600 ℃, the heating speed is between 10 ℃ and 6000 ℃, and the residence time is between 0.01 ℃ and 600 minutes. In addition, the invention also relates to the binder obtained thereby and its use.
