Through the combination of TIPA and molasses, the enhanced grinding aid was studied, its grinding effect and reinforcing effect were tested, and the grinding mechanism and strengthening mechanism were discussed. 

The results showed that TIPA combined with molasses could make the specific surface area of cement. Increasing 20~25m2/kg, the 45μm sieve is reduced by 2.2%~3.1%, the 3d compressive strength is slightly improved, and the 28d compressive strength is increased by about 10%, showing good grinding effect and post-strong effect. In the case, TIPA-molasses is used as a reinforcing grinding aid to replace clinker with more than 5% of the clinker under the premise of ensuring the strength of the cement.
