Mortar testing

Compressive strength is a test routinely used to measure the end performance of hardened mortar. It is applicable for production control, performance and compliance testing. With regards to analytical investigation and the assessment of in situ mortar, compressive strength cannot be determined due to insufficient specimen size of the placed mortar.
