Lightweight concrete foam brick equipment for sale
Lightweight concrete foam brick is one of the bricks commonly used in construction engineering. It is different from ordinary bricks and it has a good anti-seismic effect. Many friends may not know what is lightweight concrete foam brick and concrete foam brick. Here is a brief introduction to you what is lightweight concrete foam brick? And the ten properties of lightweight concrete foam brick.
1. Light capacity: The absolute dry capacity of lightweight concrete foamed bricks is only 500-700Kg / m * 3, which is 1/3 of 1/4 clay of ordinary concrete and 1/2 of hollow blocks. Small, commonly known as aerated concrete floating on the water, the use of this product in construction can reduce the weight of the building and greatly reduce the overall cost of the building.
2. Insulation and heat insulation: During the manufacturing process of aerated concrete, tiny pores are formed inside, and these pores form an air layer in the material, which greatly improves the thermal insulation effect, so that the thermal conductivity of the aerated concrete is 0.11- 0.16W / MK. The thermal insulation effect is 5 times that of clay bricks and 10 times that of ordinary concrete.
3. Sound absorption and sound insulation: The porous structure of aerated concrete has good sound absorption and sound insulation performance, which can create an indoor space with good sound insulation effect and provide you with a quiet and comfortable living environment.
4. Small shrinkage value: due to the use of high-quality river sand and pulverized coal as the silica material, the shrinkage value of the lightweight concrete foamed brick is only 0.1-0.5mm / m, and the small shrinkage value can greatly reduce wall cracking .
5. Impermeability: The pore structure of the lightweight concrete foam brick makes its capillary action poor, the water absorption and moisture conduction are slow, and the time required for the same volume of water absorption to saturation is 5 times that of the clay brick.
6. Environmental protection: no pollution during manufacturing, transportation and use, protect cultivated land, save energy and reduce consumption, and belong to green environmental protection building materials.
7. Earthquake resistance: The use of lightweight concrete foam bricks in the same building structure can increase the earthquake resistance level by one compared to clay bricks.
8. Durability: The long-term strength of lightweight concrete foamed bricks is stable. After one year of exposure to the atmosphere of the test piece, the strength is increased by 25%, and it remains stable after ten years.
9. Machinability: Lightweight concrete foam bricks are light in weight and diverse in size and size, which is convenient for nailing, drilling, chopping, sawing, laying pipelines, etc., and the use of expansion pipes on the wall can directly fix the hanging cabinet, air conditioning, Range hoods, etc., bring convenience to hydropower installation and home decoration.
10. Fire resistance: The fire resistance is 700 degrees, which is a first-grade refractory. The fire resistance of 100mm thick blocks is 225 minutes, and the fire resistance of 200mm thick blocks is 480 minutes.
