Wax shale gray slag base polymer gelled material

Abstract

The invention relates to a cementing material of an oil shale clinker matrix polymer and a preparation method thereof, and belongs to the field of environment-friendly materials. The cementing material comprises the following components in percentage by weight: 30 to 70 percent of oil shale clinker with the particle diameter of 200 meshes, 0 to 70 percent of low-temperature calcined kaolin with particle diameter of 200 meshes, 0 to 10 percent of calcium lime with the fineness of 150 meshes, 5 to 30 percent of P32.5 cement, and 5 to 10 percent of exciting agent, wherein the exciting agent is a mixed solution of industrial sodium silicate of which modulus M is 3.3 and industrial alkali. The cementing material can replace the prior cementing material gypsum and cement, and is suitable for manufacturing stone imitated artworks, embossing wall bricks, sculptures and ground tiles for building decoration and products such as hollow bricks, light bricks, and the like for building materials. The cementing material has low cost and performance superior to the prior material.

Description

[0001] The invention relates to a geopolymer cementitious material whose main component is oil shale ash and a preparation method thereof. The cementitious material uses the oil shale ash, which is the waste produced in the dry distillation process of Fushun Mining Group, as the main raw material, uses low-temperature calcined kaolin and cement as reinforcing materials, and adds quicklime and an appropriate amount of activator materials, such as sodium hydroxide Or potassium hydroxide, which is obtained by blending and stirring with a mixer for a certain period of time. technical field [0002] The invention relates to a method for preparing a gelled material, which belongs to the technology of light building materials, and specifically relates to a method for preparing and using a mineral waste slag-based geopolymer material. Background technique [0003] Oil shale ash is the product of oil shale dry distillation, which belongs to slag waste, and a large amount of accumulat...

AI Technical Summary

Problems solved by technology

[0003] Oil shale ash is the product of oil shale dry distillation, which belongs to slag waste, and a large amount of accumulation causes serious environmental pollution and waste of resources

At present, the treatment methods of oil shale ash are mainly landfill and accumulation. Since there is no mature comprehensive utilization method, it not only causes a relatively large adverse impact on the surrounding environment, but also is a huge waste of resources.
