What is a brick pressure testing machine?
In the construction industry, the quality of bricks is directly related to the safety and durability of the building. In order to ensure that the compressive strength of bricks meets the standards, the brick pressure testing machine has become an indispensable testing equipment. This article will introduce in detail the definition, working principle, application scenarios and related technical parameters of the brick pressure testing machine to help you fully understand this important equipment.
1. Definition of brick pressure testing machine
The brick pressure testing machine is a device specially used to test the compressive strength of bricks, blocks and other building materials. By applying gradually increasing pressure, it measures the maximum pressure a brick can withstand before it fails, thereby assessing whether its compressive performance meets national standards or industry requirements.
2. Working principle of brick pressure testing machine
The working principle of the brick pressure testing machine is relatively simple but very effective. Here is its basic workflow:
1. Place the brick sample on the pressure platform of the testing machine.
2. Apply vertical pressure to the bricks through a hydraulic or mechanical system.
3. The pressure is gradually increased until the brick cracks.
4. Record the maximum pressure at which the brick breaks.
5. Calculate the compressive strength of the brick based on its compressive area.
3. Main technical parameters of brick pressure testing machine
| Parameter name | Typical value | Description |
