Proper usage of Cement While Construction
An optimum quantity of cement must be used for any construction. It is a myth that high grade cements can be used in lower quantities. If lower quantities of cements are used, then an additional quantity of water is required. This would mean a distorted water to cement ratio, and the result would reduce the strength and durability of the concrete.
A common misunderstanding is that high grade cements result in better results. The grade of cement only indicates its compressive strength after a period of 28 days. However, blended cement continues to increase in strength beyond that period. Therefore, with the long term objective of a lasting home, blended or composite cements are usually preferred. Yet another misconception is that quick seeking cement should be used. It is advisable to allow all concrete structures the requisite time for setting.
Ask the mason or contractor to be patient if they complain about the time it takes to set. Slower setting cement does not necessarily mean that it will not provide long-term strength.
Some people believe that the colour of cement determines its quality. This is totally untrue. The colour of the cement is determined by the quantity of the raw materials used in its manufacture.
