What are the specifications and sizes of autoclaved lime-sand bricks?

A, lime sand brick specifications (lime sand brick size)

240mm× 1 15mm×53mm, and the void ratio is 0%.

240mm× 1 15mm×90mm, with a void ratio of 25%.

240mm×115mm×115mm, and the porosity is 25%.

Second, the performance of lime-sand brick-frost resistance

After freeze-thaw cycle, the mass loss of single brick is less than 2%, and the strength grade of superior products is not less than MU 15.

In GB GB-1999, the standard mechanical properties of lime-sand brick stipulate four strength grades, such as mu10.mu20.mu25. ..

Performance-mechanical properties of lime-sand brick (strength of autoclaved lime-sand brick) Note: The strength grade of superior products shall not be lower than MU 15.

Volume density of lime-sand brick

Fly ash brick is a new wall material, and its bulk density is one of its main technical indexes. The bulk density can be controlled by adjusting the process formula according to the needs of the building.

The absolute dry bulk density of fly ash brick is about 1540 ~ 1640kg/m3. Slightly lighter than clay brick (clay brick 1600 to 1800 kg/m3).

Other properties: Compared with other wall materials, lime-sand brick has remarkable heat storage capacity. Lime-sand brick has excellent sound insulation performance because of its large capacity. In addition, lime-sand brick belongs to non-combustible building materials. Lime-sand bricks shall not be used for building parts that are heated for a long time over 200 degrees, quenched and heated rapidly, and have acid hardness.
