Embodiment 1

[0017] Weigh 520kg of high-alumina cement, 110kg of finely ground fly ash, 250kg of blast furnace slag and 120kg of kaolin according to the specified proportion, put the batching materials into the mixer, and mix them well to obtain high temperature and quenching resistant cement Composite cementitious materials.

Embodiment 2

[0019] Weigh 580kg of high-alumina cement, 140kg of finely ground fly ash, 180kg of blast furnace slag and 100kg of kaolin according to the specified proportion, put the batching materials into the mixer, and mix them well to obtain high temperature and quenching resistant cement Composite cementitious materials.

Embodiment 3

[0021] Weigh 650kg of high-alumina cement, 190kg of finely ground fly ash, 100kg of blast furnace slag and 60kg of kaolin according to the specified proportion, put the batching materials into the mixer, and mix them well to obtain high temperature and quenching resistant cement Composite cementitious materials.

[0022] Mix the cement composite cementitious material prepared in the above examples with a certain amount of coarse aggregate and fine aggregate, add water and stir well, then shape and maintain, and finally obtain a product that is resistant to high temperature and quenching. The product will not crack at a high temperature of 700°C; it will not crack when cooled with water at a high temperature.

Abstract

This invention relates to a preparation method for refractory and anti-quencher cement compound gel material including the following steps: 1, determining a formula of raw materials and their weight percentages: alumina cement 50-70%, powdered coal ash 10-30%, tap cinder: 10-30%, kaolin 5-15%, 2, weighing and preparing the materials in terms of the formula and putting the materials in a mixing mill, mixing them fully and uniformly to get the compound gel material to be matched with rough aggregates and fine aggregates and added with water to be mixed fully and uniformly to be molded to a product then to be nurtured to become refractory and anti-quencher product.

Description

technical field [0001] The invention relates to a preparation method of a high-temperature-resistant and quench-resistant cement composite cementitious material, which belongs to the technical field of inorganic cementitious material preparation technology. Background technique [0002] In the field of materials, all materials that can bond bulk or bulk materials into a whole through a series of physical and chemical actions are collectively called cementitious materials. Common inorganic cementitious materials include cement, lime, gypsum, etc. Such as cement, which is a powdery solid. When cement and water are mixed, the physical and chemical reaction process can change from a plastic slurry to a hard stone-like body, and can cement granular materials into a whole. Non-incoming materials made of cement, lime, gypsum and other cementitious materials are generally not resistant to high temperature and sudden cooling after hardening in air or in water; or they are prone to c...
