Dec 27, 2018 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 indicates the compressive strength of cement, i.e. 53 grade of cement indicates that compressive strength of cement cube after 28 days of curing will be 53 N/mm 2 (MPa) or 530 kg/cm 2.
Read MoreStrength is the most important property of cement. The compressive strength test of cement is done because, with an increase in compressive strength of cement strengths such as flexural strength, resistance to abrasion, and so on also increases.With one test we can determine various aspects of cement and can decide the suitable types of cement for the construction site.
