What it is
A prepared full unit or specified specimen is loaded through level bearing faces until failure.
Public test guide
Building-block compressive strength
Measures the compressive load a concrete building block can withstand.
Plain-language explanation
What the test tells you.
The project specification controls the exact method and acceptance requirement.
What is used
Representative blocks, dimensional tools, bearing/capping materials and calibrated compression machine.
What it determines
Maximum load and the required compressive-strength result for the unit geometry.
Why it matters
Supports manufacturing quality control and verification for loadbearing or non-loadbearing masonry use.
Typical test sequence
From sample
to result.
- 01
Condition, inspect and measure the block
- 02
Prepare and align the bearing surfaces
- 03
Load to failure and calculate the result
