crushing strength of ordinary portland cement

In Grade 53Portlandcementthe low content of chloride was present and the grade 53cementhas a good ability to resist sulfate. The Quantity of thecementis required less in volume because this grade has highstrengthas we compare to the otherPortlandcementgrades. Grade 53cementis mainly used in: R.C.C Bridges.

Cementis a commonly used binding material in the construction. Thecementis obtained by burning a mixture of calcareous (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in England in 1924. He patented it asPortlandcement.

Importance:Cementis usually subjected to compressive stresses when used in the form of concrete or mortar. The most comprehensive test forcementor for a mixture of it with sand is done by determining itscrushingstrength.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.
