description	The invention relates to a mortar admixture and a preparation method and a use method thereof, the mortar admixture comprises the following raw materials in parts by weight: 40-60 parts of sodium gluconate, 30-45 parts of white sugar, 7-12 parts of an air entraining agent, 1-3 parts of cellulose ether, 1-3 parts of a water-retaining agent, 110-140 parts of a polycarboxylate superplasticizer and 4-6 parts of a carbon shielding agent, and the carbon shielding agent is sodium dodecyl benzene sulfonate. Due to the addition of the carbon shielding agent, the carbon shielding agent is preferentially adsorbed by carbon pores in the fly ash, so that the air entraining agent is difficult to continuously absorb by the carbon pores, and the aim of improving the anti-freezing performance of the mortar is fulfilled; the method has the advantage that the anti-freezing performance of the mortar is further improved; the use method of the mortar admixture has the advantages that the operation is simple, and the mixing uniform
