Abstract
The influence of $H_3BO_3$ in one of inorganic retarder for the hydration of OPC was investigated. The shape of needdle Ettringite formed in few minitues for a no addition of $H_3BO_3$ but, retarded to form of Ettringite and $Ca(OH)_2$ according to addition of $H_3BO_3$. Hydration was retarded for tranquil of Al ion by to be low of pH.
