This formula is good, and the quality is guaranteed. Depending on the market, you can choose to add calcium formate or not, or you can make two formulas. For example, if in the south, your formula is okay, you can consider not adding calcium formate; if in the north and the construction is winter, then calcium formate still needs to be added with a significant amount. If too much calcium formate is added, it will quickly become alkaline in areas with high ambient temperatures.
