Cement mortar preparation process

The invention relates to the technical field of cement mortar preparation, in particular to a cement mortar preparation process which comprises the following steps: step 1, preparing raw materials, weighing cement, sand and water, and controlling the temperature to be 10 DEG C or above; 2, the weighed raw materials are guided into mixing equipment to be stirred; step 3, putting quick lime into a sedimentation tank, adding water to lime, and obtaining lime paste after 20-32 hours; step 4, introducing the obtained lime paste into mixing equipment, and adding fly ash and an additive emulsified asphalt into the mixing equipment; and step 5, controlling the temperature in the mixing equipment, keeping the temperature in the range of 35-45 DEG C, and continuously stirring for 2-3 hours, thereby completing the preparation of the cement mortar. In the preparation process, the mixing equipment is adopted to stir the raw materials, and compared with vertically arranged equipment, the equipment can effectively improve t
