The result showed that the strength of facing mortar was the best when gelatin powder was 2%, metakaolin was 2.5%, hydrophobic agent was 0.3%, calcium carbonate was 15%. Metakaolin and gelatin powder had great influence on the strength, hydrophobic agent and calcium carbonate had little effect on the strength through ranger analysis. Using the hydrophobic agent could make the water absorption meeting JC/T 1024-2007. The product was CaCO precipitated white eff
