2017 6 16 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 sie of the placed mortar.
Get Price2010 10 7 The strength of cement is determined by TS EN 196 1 in Turkey that is the same for all types of cements. However American cement producers use different standards for testing the strength of Portland cement and blended cements. The main difference is the amount of water utilied in producing the cement mortar.

Get PriceImportance Cement is usually subjected to compressive stresses when used in the form of concrete or mortar. The most comprehensive test for cement or for a mixture of it with sand is done by determining its crushing strength.Unfortunately it requires a very costly machine and therefore the usual practice is to use the tensile test instead which can be carried out very cheaply.
