Pastes with abundant raw materials, the protection of arable land, energy conservation, waste utilization, production process is simple, plant investment, do not pollute the environment and so on. Solve the brick building, reducing destroying the brick, red brick unburned sintering is a partial substitute for good material.

    In recent years, with the unburned depth research carried out, and wide application, so that only the first clay plus two kinds of cement and lime unburned clay, and now have a variety of unburned. To sum up can be divided into the following three categories.

First, according to the classification of raw materials

(1) soil, cement and admixture compression molding.

(2) red, yellow, lime and admixtures pressing, then steam curing is made.

(3) sand, cement and admixtures pressing.

(4) fly ash, cement and admixture pressing.

(5) tailings powder, cement and admixtures pressing.

(6) municipal waste lime, fly ash and gypsum pressing, then steam curing is made.

(7) weathered granite sand, cement and lime plus admixture pressing.

(8) diatomite lime, cement and admixture pressing.
(9) iron powder added to granulated slag tailings, lime and azurite pressing.
(10) slate, quartz sand plus cement pressing.
(11) plus kaolin cement pressing.
Second, the classification according to the type of curing agent
(1) the cement as a curing agent.
(2) for the week of lime and.
(3) engage in lime stone plus a curing agent.
(4) cement and lime as a curing agent.
(5) high cement lime and stone as a curing agent.
(6) lime, calcium fly ash as a curing agent.
(7) sodium silicate as a curing agent.
Third, the use classification
(1) unburned wall bricks.
(2) unburned brick.
(3) unburned refractory bricks.
    Now widely used in cement as curing agent, mountain soil as a substrate manufacturing unburned. The Act manufacturing process is simple, just cement and mountain soil by mixing, add water stir, pressing Serve. After the use of mountain soil brick, combined with mountains farmland, protecting farmland, mountain or hill biting zone so greatly benefited farmers. Power plant in the city where there is extensive use of fly ash cement and admixture manufacturing unburned. Use of industrial waste produced bricks, help protect the environment and ecological balance. Followed by curing agent with lime, red, yellow as unburned material manufacturing base, the method uses steam curing process, can be used in a conditional place.
