Abstract
The invention discloses a preparation method of cement mortar. The preparation method comprises the following steps: weighing the following components in parts by weight: 70 to 80 parts of cement, 10 to 15 parts of gypsum, 10 to 15 parts of fly ash, and 50 to 55 parts of water, adding the components into a stirring machine, stirring; then weighing the following components in parts by weight: 10 to 12 parts of shale, 5 to 7 parts of diatomite, and 3 to 5 parts of calcium fluoride, adding the components into a pulverizing mill, carrying out pulverizing for 20 to 30 minutes, heating to a temperature of 200 to 300 DEG C to obtain high temperature powder; adding the high temperature powder into the stirring machine, mixing, adding 3 to 5 parts by weight of additive and 7 to 10 parts by weight of emulsified asphalt, then adding 35 to 45 parts by weight of water during the stirring process, heating the temperature to 40-50 DEG C again during the stirring process of stirring machine, and keeping on stirring for 0.2 to 0.5 hour to obtain the cement mortar. When cement, sand, gypsum, and water are stirred in the stirring machine, the temperature is controlled to be above 20 DEG C so that cement and sand can be rapidly dissolved into water, a cement antifoaming agent can eliminate bubbles generated during the process of cement stirring, and a cement enhancer is added into the cement mortar to improve the binding force and anti-cracking performance of cement mortar.
Description
Technical field
