325 cement "325 cement" is just a popular saying in the market, not a specific cement variety. R in cement label indicates early strength type, for example, P.O32.5R indicates early strength type ordinary portland cement with strength grade of 32.5. The strength grades of ordinary cement have been cancelled from 32.5 and 32.5 r, so the only 325 cements on the market now are slag portland cement, pozzolanic portland cement, fly ash portland cement and composite portland cement. Portland cement No.325 and ordinary Portland cement are gone.
