Abstract
The invention discloses a hollow shale brick made of natural shale as raw material, which comprises silicon oxide 55-70%, ferric oxide 2-10%, aluminum oxide 10-25%, calcium oxide 1-5%, magnesium oxide 0.1-2%, sodium oxide 0.01-0.05%, potassium oxide 3-8%, sulfur trioxide 0-1%.
Description
Technical field
The present invention relates to a kind of building brick and production method, particularly relating to a kind of is the shale hollow brick and the production method of raw material production with shale.
Background technology
Existing building brick is a raw material with the clay generally, causes large quantities of soils to be ruined, and in order to protect farmland, country repeats injunctions and requires the cancellation clay brick.After clay brick was banned, flyash, industrial residue brick constantly came out, and they are turned waste into wealth, and have increased color to building brick, still, the phenomenon that these products easily produce heat, split, leak, the brick body is not firm, is not suitable for building trade and uses.
Summary of the invention
The object of the present invention is to provide a kind of shale that produces with the Yanshan Mountain is raw material, utilization of waste material, and scientific structure design is reasonable, the shale hollow brick that performance is good.
The present invention also aims to provide a kind of production method simple, the production method of the shale hollow brick of being convenient to operate.
Technical solution of the present invention is: a kind of shale hollow brick, it is a raw material with natural shale, the index content of raw material is, silicon oxide 55-70%, ferric oxide 2-10%, aluminium sesquioxide 10-25%, calcium oxide 1-5%, magnesium oxide 0.1-2%, sodium oxide 0.01-0.05 potassium oxide 3-8%, sulphur trioxide 0-1%.
A kind of production method of shale hollow brick in turn includes the following steps:
A, fragmentation: the shale building stones are pulverized it with crusher, gone into Φ 6-10 sieve, undersized powder is the brick raw material,
B, add water mixing ageing and after 72 hours the shale powder is put into stirrer, the shale powder adds water 8%, fully stirs the base raw material;
C, go into the blank machine base: raw material is gone into blank machine, be pressed into hollow base substrate, take out the base substrate airing;
D, fire: with the base substrate kiln-firing of airing 3-4 hour, temperature was controlled at 1050 ℃.
Owing to adopted technique scheme, the shale that the present invention produces with the Yanshan Mountain is raw material, and aboundresources is turned waste into wealth, and can save a large amount of clay resources.The brick of being produced is a hollow structure, and is rational in infrastructure, meets the code requirement of national walling building trade.Sturdy and durable, compressive resistance is strong, and plasticity index is 9-13.It is fast to build speed by laying bricks or stones with this product, is convenient to operation.
