Q:What are the main constituents in non clay brick sintering?

Unfired bricks are bricks used to build walls relative to sintered bricks.

Q:Which is more useful, aerated concrete block or clay brick?

How to evaluate the porous brick right (aerated concrete block), the practicability of the clay brick, brick which is first aerated concrete block, aerated concrete block and clay brick is the coexistence of wall materials, only the current use rate than the aerated concrete block of clay solid brick.

Q:The making process of clay brick

Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks. In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

Q:What is the coefficient of heat transfer for clay bricks?

The coefficient of heat transfer is called the total heat transfer coefficient. The current standards and specifications of the state are uniformly named as heat transfer coefficients. The heat transfer coefficient K value refers to the stable heat transfer condition, both sides of retaining structure air temperature is 1 degrees (K, c), 1s in the area of 1 square meters of the heat transfer unit, is w / (M2 - degree (W/) m - K, where K can replace c).

Q:Where the refractory bricks rider bricks that are used for building arch and vault should be put?

Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.

Q:What types of building blocks do you have?

The commonly used shapes are mainly divided into hollow bricks and perforated bricks. In particular to the green landscape construction, decoration materials, building construction, there are many such as: ordinary brick, lime sand brick, sintered shale brick, porous ceramsite concrete permeable brick, lawn brick, pervious brick, hollow glass brick, ceramic tile ground, refractory clay, concrete block wall, floor tiles, solar LED lamp, floor tile dry spray the rubber brick, grass planting brick, brick, split brick, road brick.

Q:What is the perservation method for refractory bricks used for cement kiln?

The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof

Q:What is the size of mechanism brick and general refractory brick?

The ordinary refractory brick is 230mm long, 53mm thick; red brick is 240mm long, 115mm wide, 65mm thick,

Q:can the red brick be used as refractory brick?

1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.

Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?

1, Portland cement should be. Should use aluminate cement CA625. 2, and high alumina fragment yellow sand limestone should be mixed with high temperature solution 3, add some area of reinforced steel and steel can be thin or thick, but 6mm's diameter and 50mm's spacing of steel are suggested 4, according to the situation, add CA625 about 15%, brickbat about 60% and brick powder about 25%; 5, mixing with water to cement mortar until it is slightly thicker
