What is the standard test for determining the compressive strength of cement?

Step 1: Prepare a sample of hydraulic cement and mix it with sand and water to create a mortar.
Step 2: Place the mortar mixture into a mold to form a test specimen.
Step 3: Allow the specimen to cure for a specified period, usually 28 days, to gain strength.
Step 4: After curing, remove the specimen from the mold and place it in a compressive strength testing machine.
Step 5: Gradually apply pressure to the specimen until it fails, recording the maximum load it can withstand.
Step 6: Calculate the compressive strength by dividing the maximum load by the cross-sectional area of the specimen.
