Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
    Cement brick production of cement concrete mix proportion design of tailings cement block is to be based on material design requirements and molding conditions to determine the batch of concrete cement slabs ratio between the components, namely cement per cubic meter of concrete C, thick bone material G, fine aggregate S, additive M, the amount of water W. Concrete has: 1 and adapted to the conditions of forming the humidity 2. meet the requirements and design strength grade 3 with the use of the environment to adapt to the use of performance and durability 4. satisfy the most economical technical performance under the above conditions .
Tailings cement concrete brick mix design actually consists of two parts, part of the aggregate gradation design, making coarse and fine aggregate with a reasonable and consistent grading requirements, another part of the proportions of the constituent materials design. Upon completion of grading design, the remaining content is mainly based on the ratio between the performance of some research or experience, choose a reasonable ratio parameters, and use some mathematical model, we determined the specific amount of the constituent materials.
Compared with the determined parameters. Practice shows that the tailings concrete technical performance mainly to depend on three basic parameters: water-cement ratio (W / C) unit of water (W) and tailings rate. Wherein the water-cement ratio and unit water is most important.
Under the same conditions, the general W / C bigger, better operational type concrete mixture, but over the General Assembly is difficult to produce cement brick molding or body felt weak, difficult compacting concrete. W / C, the higher the concrete strength and durability, the better, but too small to make the body produce divergence caused difficulties, we can not guarantee the density of concrete.
In order to improve the concrete strength and durability of cement brick, in the case of dry humidity to meet the requirements, should be a smaller unit of water.
Concrete mix design of tailings cement brick surface density Law Section reference model. The model character, when relatively stable raw material of concrete, cement brick different mix than the apparent density concrete mix concrete is close to a fixed value, equal to the amount of the various components and materials.
