Effects of superplasticizers on the stability and morphology
NS superplasticizer can improve the stability of the ettringite below 100 °C and increase the second weight loss temperature by 20 °C. However, AS and AH superplasticizers decrease the thermal stability of ettringite.
Stability of superplasticizer on NaOH activators and influence on the
2.3. Testing methods2.3.1. Stability of SP on the activators solution. Physical stability of SPs in terms of agglomeration, separation into a layer, and color change were conducted on the SP in the different concentrations of NaOH, 0.01 M, 0.1 M, 1 M, 2 M, 3 M,5 M, and 10 M.
