Effect of cement content on strength of footing:
The result reveals that the strength of concrete Foundation increases with increasing cement content in it.
However, for concrete with cement content more than 150 kg per metre cube then the strength increases with the increase in the size of coarse aggregate up to 25 mm and decreases as the aggregate size increases beyond 25mm.
Without a proper range of cement in the mixture then low strength development or excessive shrinkage may occur leading to premature deterioration.
Thank you.
