Freshly mixed concrete is checked to ensure that the specified slump is being attained consistently.

• Slump Test

• Compressive Strength Test

Common quality control test of concrete based on 7 and 28 day curing period.

• Slump Test

• Compressive Strength Test

8 in diameter at the bottom, 4 inches diameter on top, 12 in high.

• Slump Test Cone Device

• Volumetric Measure/Cylindrical Mold

6 inches diameter, 12 inches high
