Abstract

The invention discloses a method for preparing a manganese slag-based geological polymer binder comprising: (1) the solid components of the materials are manganese slag and kaolin; the liquid components are water glass, water and activator. (2) the manganese slag is dried till the moisture content is less than 1%, and is milled in a ball mill till the specific surface is 400-600m<2> / kg, the kaolin is calcined at 900 DEG C till the kaolin becomes metakaolin, and is milled till the specific surface is 500-700<2> / kg. (3) the activator is added into the water glass solution and is mixed uniformlywith water to get a water glass solution with a water glass modulus value of 1.5-3.5 and a water glass baume of 35-45 degrees. (4) the mixed solution prepared by the step (3) is added into the mixed powder of managese and metakaolin micropowder, is stirred and moulded after uniform mixture and maintenance. The preparation method has advantages of simple technology, no pollution during the preparation process, good gelling property and strong anti-seawater erosion property using industrial waste residue.

Description

technical field [0001] The invention belongs to the category of inorganic nonmetals, and relates to a preparation method of manganese slag-based geopolymer gelling material. Background technique [0002] In the industrial production of modern building materials, cement is a very important class of basic materials. Cement production consumes a lot of resources and energy. In 2005, the total energy consumption of the cement manufacturing industry accounted for 75.5% of the total energy consumption of the building materials industry. my country's cement output has ranked first in the world for many years. At the end of 2006, the cement output has reached 1.24 billion tons, while the cement output of other countries in the world in 2006 was 1.328 billion tons. It can be said that almost half of the world's cement is in China. However, the cement industry has become an important factor affecting climate change and environmental pollution. A large amount of CO emitted by the ceme...
