What is mortar cube strength?

Mortar cube strength refers to the compressive strength of a mortar sample, typically measured using standardized cube specimens. It is determined by curing the mortar for a specified period, usually 28 days, and then testing it under controlled conditions to assess its ability to withstand applied loads. The strength is expressed in megapascals (MPa) or pounds per square inch (psi) and is crucial for evaluating the performance of mortar in construction applications. High mortar cube strength indicates good durability and bonding capabilities in masonry structures.
