The Influence of Temperatures on the Hydration of Cement Paste at the Early Age, and Behaviour of Cement Paste with the Addition of Triethanolamine (TEA) and Triisopropanolamine (TIPA)

This paper intends to examine the influence of temperatures on early age cement paste hydration, as well setting time and compressive strength with addition Triethanolamine (TEA) Triisopropanolamine (TIPA); hence, mechanisms TEA, TIPA at different curing were explored. The outcomes show that adding 0.05% 0.1% retarded pastes; however, this retardation depended both dosage temperature. At 23°C temperature, TEA could be used a hardening accelerator by weight. Adding into strongly accelerated hydration C3A increased strength, which was more efficient than TIPA, especially after 8 hours curing. However, 50°C formation AFt, AFm, CH, using effective enhance paste's strength. These results can offer theoretical direction for application cement-based materials under hot standard temperatures.
