The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.

Concrete Strength Testing Compressive or flexural strength of concrete is easily measured in a number of ways for different types of specimens. Gilson Compression Testing Machines are the stiffest in the industry and meet or exceed ASTM C39 requirements and ACI 368 recommendations for rigidity.
Whether you’re renovating a house, planning out a swimming pool, or removing snow from your roof, we’ve got you covered. These online construction calculators were created specifically for carpenters, painters, bricklayers, roofers, and craftsmen alike who switch back and forth between square feet of driveways and pounds of cement on an everyday basis.
The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the crosssectional area resisting the load and reported in units of poundforce per square inch (psi) in US Customary units or megapascals (MPa) in SI units ...
Concrete can be ordered in ½ yard increments. Slump – Slump is a measure of the consistency of the concrete. A 4 inch slump (the measure of the distance a wet concrete cone will fall) is typical. If you want more slump, it is always safest for the concrete to adjust slump at the plant. Adjusting slump at the job site will damage the concrete.
