Tests on Concrete

 · The only work done on-site is to make a concrete cylinder for the compression test. The strength is measured in Megapascals (MPa) and is commonly specified as a characteristic strength of concrete measured at 28 days after mixing. The compressive strength of concrete is a measure of the concrete''s ability to resist loads which tend to crush it.
