May 22, 2020The final setting time of OPC paste with 1%, 2%, 3%, and 4% sodium carbonate decreased by 39.95%, 53.69%, 54.96%, and 64.38% respectively compared to that of pure OPC paste. It can be seen that the influence of Na2CO3 on the initial setting time was more significant than the final setting time.

Lime Softening 1 Lime Softening . Chemical precipitation is one of the more common methods used to soften water. Chemicals normally used are lime (calcium hydroxide, Ca(OH) 2) and soda ash (sodium carbonate, Na 2CO 3). Lime is used to remove chemicals that cause carbonate hardness. Soda ash is used to remove chemicals that cause non-carbonate
