Compressive Strength • TIPA increase 7 days and 28 days compressive strength of cement. • Optimum dosage is 0.01-0.02% for the enhancement of strength by TIPA. • If dosage>optimum dosage it can increase the strength further very little but it is not economical. • Higher dosage of TIPA can cause air entrainment in cement. This air entrainment can be as high as 2% compared to the cement without any additives. • Therefore TIPA is used with air detraining agent at higher dosage.
