Effect of Alginate Admixture on Cement Paste Setting Time and Higher Strength Evolution at Early Ages

Sahil Sawant

Abstract


This study aims to determine how, at a temperature of 20 °C, the use of admixtures like alginate affects the setting and hardening of cement pastes. Tests were performed on examples from different blends thinking about two kinds of concretes. According to the findings, the calcium nitrate that was utilized on its own functions as a setting accelerator and has relatively little beneficial effect on the development of mechanical resistances over time. Both alginates alone performed well as a hardening accelerator at all ages, regardless of the cement type. With regard to both setting and hardening acceleration, as well as an ongoing increase in compressive strength over time, the combined additions produced significant and promising results at an early age.
