Abstract: The early strength of low heat cement has hindered its industrial production and the application scale .The carbonation technology is adopted in this paper in order to improve the early strength of low heat cement .Experimental results show that low heat cement strength of carbonated for 8 h is 38 .80 MPa and late strength is higher than the normal hydration cement .

Key words: low heat cement;early strength;carbonation
