Which test is used to determine the compressive strength of concrete?
Correct Answer: Cube test
- Step 1: Prepare concrete samples in the shape of cubes.
- Step 2: Allow the concrete cubes to cure for a specific period, usually 28 days.
- Step 3: Place the cured concrete cubes in a testing machine.
- Step 4: Apply pressure to the cubes until they break.
- Step 5: Measure the amount of pressure the cubes can withstand before breaking.
- Step 6: Calculate the compressive strength using the pressure measurement and the cube's dimensions.
