In order to protect precious land resources, effectively save energy, save energy and reduce emissions, and protect our living environment, the relevant state departments have imposed a ban on the use of ordinary clay sintered bricks in the construction industry, and vigorously promote the use of hollow bricks.
1. Compared with solid bricks, hollow bricks can save a lot of land and brick fuel to reduce transportation weight; light weight, concrete hollow blocks are about 1/3 lighter than red bricks, which can reduce the building's own weight.
2, high compressive strength, in addition to suitable for all types of industrial and civil building infill walls, can also be used as load-bearing walls, especially solid concrete blocks. In some areas, red bricks are often used as load-bearing walls in brick-concrete structures.
3, sound insulation, heat insulation, moisture, fire, corrosion resistance and other excellent performance.
Foreign construction hollow bricks are more common, and have been specified in detail. There are strict building height restrictions on buildings with ordinary hollow brick masonry structures. For example, in Japan, in the last century, it was stipulated that ordinary bricks, without reinforcement, were used to reinforce the building, and the height limit was below 3 floors.
