Choosing the right type of cement
When it comes to constructing a house ‘Ordinary Portland Cement’ should be used. OPC is available in three grades such as:
33 Grade Ordinary Portland Cement
Used extensively throughout the country this OPC is chosen the most. Suitable for masonry and general concrete works, this cement is used where the members do not have to face very high stress conditions. Soil or ground water containing sulphate is not ideally suitable for this grade OPC.
43 Grade Ordinary Portland Cement
Any kind of RCC work where a member has to take high tensile stress is where structural engineers advise to use this grade of cement. Typically this cement is used where high early strength is required especially in the 1 to 28 days range. It is used in general civil engineering construction work i.e. brick masonry, plastering, pointing, flooring and in RCC Work etc. 43 Grade cement attains compression strength of 43 mpa (mega pascals) in 28 days of setting.
53 Grade Ordinary Portland Cement
On the other hand, any construction that requires a faster initial strength is where 53 grade cement is used. Compared to 43 grade cement it has a comparatively faster setting. 53 mpa (mega pascals) can be attained by 53 Grade cement compared to a 43 grade. It is used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria.
The different colours of cement consist of grey and white wherein grey is majorly used for residential building construction purposes and white cement for any architectural beauty, interior and exterior decorations.
