Problems solved by technology

Cement, lime, and superfine silica fume in the auxiliary materials are indispensable raw materials as gelling agents, generally accounting for more than 15%-20% of the raw materials, so the cost of raw materials is relatively high, and because the main materials are currently limited to Coal gangue, therefore, still has the defect that the source of raw materials is not wide enough, so its production is subject to certain restrictions, and it is difficult to become the leading product of building bricks

Abstract

The present invention relates to a baking-free and steaming-free brick. It is formed from main material and auxiliary material as gelatinizing agent, the main material is stone ballast and slag, its content is 80-85 weight portions, and the gelatinizing agent is huangbanzi stone powder and quicklime, in which the huanbanzi stone powder content is 7-10 portions and the quicklime content is 6-13 portions, gran size of ballast or slag is less than or equal to 8mm, and the grain size of huangbanzi stone powder is greater than or equal to 85 meshes. Said invention adopts the processes of pressure forming and natural curing to form hydrated calcium silicate and reducing it to obtain tobermorite crystal. Said invention can use the huangbanzi stone powder and quicklime instead of cement to obtain the product similar to cement concrete brick.

Description

technical field [0001] The invention relates to building bricks for natural conservation and belongs to the technical field of building bricks. Background technique [0002] Building bricks can be divided into sintered, steam cured and natural cured according to their production methods. The production of sintered bricks requires the construction of kilns and the consumption of coal and other fuels. The black smoke emitted by the combustion pollutes the environment, especially clay sintered bricks, which have been strictly prohibited by the state due to the destruction of fields due to a large amount of soil borrowing; steam curing bricks such as Fly ash bricks, lime-sand bricks, etc. are steamed at atmospheric pressure or saturated steam after the bricks are formed, so they still need to consume steam heat energy; natural curing bricks are a new generation of buildings that have been developed and produced since the 1990s At present, there are only coal gangue bricks used ...
