Cement is the one of the most essential raw material required in construction projects. Cement acts as a cohesive agent in building a house. Hence stronger the cement stronger is the bonding.
The strength of the structure is based on the cement used, Hence it is very important to use good quality cement for a firm structure. firmly. Choosing best cement for construction, lasts longer resisting bad weathers and other conditions that affect it in any degradation.
The housing sector has the highest demand for cement always. The quality of the cement depends on its components. However the quality of the cement goes down by time, therefore it is recommended to use fresh cement for construction.
There are different grades of cement, the quality of the cement is determined after a month of its application. Ordinary Portland Cement also called as OPC is the most usual type of cement used in constructing buildings. It is available in different colors. Grey Portland cement is used in constructing residential buildings where the white Portland cement is usually used for interior and exterior decorations.
There are three grades of OPC cements in India:
33 Grade Ordinary Portland cement: This grade is the most extensively used cement in the country. 33 Grade is useful for masonry works and some common concrete works. Wherever the structure does not have to face adverse conditions, this cement is used there. The strength of 33 grade cement is calculated based on 28 days period. 33 grade cement assures the quality paint life, breath-ability of the wall is maintained which prevents the patches on the wall.
43 Grade Ordinary Portland Cement: Where there is need to tolerate high stress and tensile pressure, usually 43 grade cement is used in such projects. This type of cement is usually used in flooring, plastering, painting, brick masonry. 43 grade cement is more adhesive than the 33 grade cement. 43 mega pascals strength is attained in a period of 28 days. The bonding capacity is better and durability of this grade is so high that it can withstand adverse effects of weather.
53 Grade Ordinary Portland Cement: A building which requires higher / quicker strength in the initial stages, prefers grade 53. This setting is stronger when compared to grades 33 and 43. It also attains 53 mega pascals strengths within 28 days of setting. Grade 53 cement is usually used in RCC and prestressed concrete for higher grades, instant plugging mortars and cement grouts. The volume is more for the weight which results in better quality and fineness.
Below are few additional tips to choose right quality of cement:
– The cement should not have any other particles or lumps in it.
– Cement should always feel cool to bare hands.
– It should be fine and not rough, smoothness can be checked by rubbing it between your fingers.
– The cement bags should be used immediately after the seal is opened.
These are a few tips and information on selecting the right quality of cement to be used in constructing a house or apartment.
