Pastes with different porous cement ratio and unburned. When the porous brick machine with soil or other materials chemical action, to raise steam, to get stable strength, its production process is very different bricks and cement. 1OMPa now required strength of brick, the base material for the yellow loam, a lime, using 100 ℃ steam curing process, the mixing ratio of brick steps are as follows:

     1 Find the lime content (%)

     Lime content and the compressive strength of the relationship, such as the strength of the brick is 100MPa, brick surplus coefficient of 1.3, the strength of the design of the tiles is 10 × 1.3 = 13MPa, according to information the lime content of 7.8%.

     2 Find the soil content of <%)

     Plus the total mix of lime soil dry material is 100% known lime content of 7.8%, Tetouan content is 100% a 7.8% = 92.2%.

     3 Find the moisture content (%)

     Optimum moisture content of the porous unburned mainly determined by technology, especially close relationship with the molding pressure. Brick moisture content 9-17%, more preferably 10% of the water content of the currently selected cases.

    When the poor quality of lime, may be appropriate to increase the amount of lime. 10 - 15MPa grade brick, basically meet the general building requirements, if required 20MPa brick, can increase the amount of cement. Brick may be appropriate to increase the steam curing temperature, the strength will increase. For agricultural residential construction, cement bricks, in general, if adding 7% of 425 ordinary silica salt cement, brick strength can be achieved l0MPa.

     Commonly used additives have gypsum, calcium lignosulfonate class superplasticizer of naphthalene superplasticizer, as FDN superplasticizer, and so on. Early strength superplasticizer has S-type, etc. superplasticizer. Now on the market for sale of many types of concrete admixtures, the general said, anything that can improve the early strength of concrete and reduce the amount of cement in these early strength agent and reducing agent, are suitable for unburned admixtures. But beware, for a retarding effect and the role of air-entraining admixture, can not be used as unburned admixtures.

    Plus a small amount of additives, such as increase the amount of superplasticizer cement consumption is only 0.2 - 5%.

    The purpose is to improve the admixture added strength and reduce brick brick costs, if the cost is higher than after adding additives to improve the amount of cement plus costs, you should choose the most appropriate to improve the cement plus. The addition of a process by the addition of additives, the production is more complicated when adding cement admixture can not replace the role should be selected admixtures.
