How to use set retarders with CSA cements in concrete

Unlike portland cements, CSA cements can use ordinary citric acid, often at doses of 0.2% to 0.4%. Straight CSA cements such as Rapid Set Cement actually benefit from moderate retardation. The structural silicate crystal growth occurs more slowly, and like old-growth wood, results in better concrete with higher strengths.
