Mortar is one of the most important materials of
construction. It is a paste generally made by mixing cementing or binding (lime
or cement) and inert materials (sand or surki) with water.
The strength
of mortar is tested by preparing a sample. In different days mortar shows
different strength as it acquires its age or maturity.
The relationship among different days: We tested 72
mortar samples of different ages and different mixing ratios. Here we present
the comparison,
Compare with 3 days,
7
days strength = 40% more than 3 days strength
14
days strength = 75% more than 3 days strength
28 days
strength = 95% more than 3 days strength
Compare with 7 days,
14 days strength = 25% more than 7 days strength
28 days strength = 40% more than 7 days strength
Compare with 14 days,
28 days strength = 10% more than
14 days strength
