AI Technical Summary
Technical Problem
Existing cementitious compositions face challenges in achieving high compressive strength within a short time after mixing with water, and there is a need for new accelerating admixtures, especially with the increasing use of blended cements.
Method used
The use of alkanolamine N-oxides as admixtures in cementitious compositions to increase the strength, particularly the compressive strength, of these compositions at early and late ages.
Benefits of technology
The incorporation of alkanolamine N-oxides significantly enhances the compressive strength of cementitious compositions at various ages, including 1 day, 7 days, and 28 days, addressing the need for accelerated strength development.
