In this study a
correlation is tried to formulate between strength and duration for mortar. For
this purpose same quality of cement and sands of two different FM are
selected. W/C ratio is kept constant.
Data is collected at different duration. It is seen from the study that 40% more strength is observed at 7 days
with respect to 3days, 25% more
strength is observed at 14 days with respect to 7 days and 10% more strength is observed at 28 days with respect to 14 days.
Detailed result is presented in terms of equation and graph.
It is also found from
the study that the mortar of finer sand acquire less compressive strength than the
mortar of coarser sand. It can also be noted that curing is very much important
for acquiring compressive strength for mortar.
