TESTING OF HARDENED CONCRETE. Compressive Strength (f'' c) Test. Most common test by far (even more than slump) 2:1 cylinders cast in 3 layers rodded 25 times each layer and cured at 95% humidity. Or specimens are cored from structure. 7 day = 60% of 28 day and 28 day = 80% ultimate strength. Typical compressive strength is 3,000 6,000 psi. 23

The SLUMP test shows the WORKABILITY of concrete. Workability measures how easy the concrete is to place, handle and compact. See CHAPTER 2 Concrete Properties The COMPRESSION test. The COMPRESSION test shows the best possible strength concrete can reach in perfect conditions. The compression test measures concrete strength in the hardened state.
Concrete and Cement are the most widely used building materials in the construction industry for over 100 years. Over the years, this construction material has been enhanced and developed to fit to the usage and requirements at site. Several researches are happening around this topic to increase the durability, strength and performance of this building material.
the testing anvil before commencement of a test to ensure reliable results. The testing anvil should be of steel having Brinell hardness of about 5000 N/mm. The supplier/manufacturer of the rebound hammer should indicate the range of readings on the anvil suitable for different types of rebound hammers.
