TECHNICAL FIELD
[0001] The utility model relates to a kind of sample preparation equipment of brick compressive strength test. BACKGROUND
[0002] In the process of construction, the compressive strength test needs to be carried out on the brick, and the method of compressive strength test requires that the number of a group of tests is 10 blocks. When preparing samples, the test sample needs to be sawn into two half bricks. The two half bricks are stacked with the cut surfaces opposite each other, and the overlapping part should not be less than 100 mm. That is, the compressive strength sample. If the length of the two half bricks used for the overlapping part is less than 100 mm, a spare sample should be used to make up for it.
[0003] During the compressive strength test, the test sample is placed flat in the center of the pressure testing machine's pressing plate. The load is applied perpendicular to the pressure surface, and should be uniform and smooth. It should not be impacted or vibrated. The loading speed is preferably (2-6) kN / s, until the test sample is destroyed. The maximum destruction load is recorded.
