Block bricks are bricks made up of cement and some aggregates such as stone chips, yellow sand, black sand, thermoelectric slag, industrial waste, soil, etc.
The main block brick is concrete with a low percentage of water and small aggregates that are compacted in a steel mold into molded shaped products, and then cured until the hardness reaches the grade corresponding to the grade. This type of brick is produced and used the most among unburnt bricks.
Advantages of block bricks
High durability because block bricks are made from concrete under high pressure saturated steam condition through autoclaving process.
Block bricks usually have good bearing strength (over 80kg/cm2), high density (usually over 1900kg/m3), but perforated structures have a smaller volumetric weight (under 1800kg/m3).
Good sound insulation
The blocks when combined together will bring natural sound dissipation thanks to their air bubble structure and sound absorption mechanism.
With such characteristics, whether the sound from outside or the sound from the inside, it will have to move in the zigzag direction, the structure of the sound wave is therefore broken and divided, from That will reduce the volume noticeably. With this advantage, block bricks are extremely suitable for building townhouses and apartments close together.
Good insulation, energy saving
Block is a brick with extremely low coefficient of thermal conductivity, so this material will insulate very well in the summer and reduce heat loss in the winter, contributing to giving you a comfortable environment. cool time when it's hot and warm when it's cold, thereby saving energy for efficient air conditioning.
In addition, the walls built of block bricks can withstand heat up to 1,200 degrees Celsius when a fire occurs, when suddenly cold water is sprayed to extinguish the fire, the structure of the brick is not changed. ensure safety when a fire occurs within 4 hours.
Environmentally friendly
This type of brick is composed of cement, stone chips, black sand, yellow sand and some industrial-agricultural wastes, so it is very environmentally friendly, the production does not cause pollution. The image of clay mining is as widespread as terracotta bricks.
During the shaping process, the block brick does not go through the firing process in the kiln, causing exhaust fumes, so it does not affect the living environment.
Defect
The horizontal bearing capacity is lower than that of traditional bricks.
Poor waterproofing bricks easily cause wall cracks due to expansion.
Mold stains may appear after use
The price is higher than many other types of bricks
The volume is much heavier than fired bricks, red bricks.
