| Questions And Answer | Back Directory | [Uses]
my country has a massive cement production, with large-scale cement enterprises producing hundreds of millions of tons annually, accounting for approximately 60% of the world's total cement production. Diethanolmonoisopropanolamine (DIPA), as a cement grinding aid, enhances strength, reducing clinker usage and coal-fired power consumption in clinker production. The addition of DIPA improves the unconfined compressive strength of cement-soil in the early, middle, and late stages. With increasing dosage, the strength improvement initially increases and then decreases, but remains higher than the baseline group. The experimental group with a dosage of 0.04% showed significantly higher strength than other groups, with the highest strength increases of 27.7%, 43.8%, and 34.3% compared to the baseline group at 7 days, 28 days, and 90 days, respectively. DIPA can improve the unconfined compressive strength of cement-soil in the early, middle, and late stages, making it an excellent cement-soil admixture. Compared to the baseline group, the highest strength increases of 27.7%, 43.8%, and 34.3% were observed at 7 days, 28 days, and 90 days, respectively. The optimal dosage of 18% has the strongest effect on improving the strength of cement-soil. |
