compressive strength ofi testing equipment inc.

20191028&ensp 0183&enspwe offer a complete line of products for testing the compressive strength of well cement. our curing chambers create 2" cubes that meet api guidelines. these cubes are then used in our clf40 compressive load frame (also known as a compressive strength tester) which crushes them to determine compressive strength.

tests to check the compressive strength of cement

cement basically is known by its compressive strength.cement is identified by its grade like 53 grade 43 grade 33 grade of cement. this grade indies the compressive strength of cement i.e. 53 grade of cement indies that compressive strength of cement cube after 28 days of curing will be 53 n/mm 2 (mpa) or 530 kg/cm 2.

tensile strength of cement determine the tensile

importance: 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.
