Example Embodiment
[0020] Example 1
[0021] In the embodiment of the present invention, a compressive and moisturizing wet-mixed mortar is composed of the following raw materials in terms of mass percentage: cement 18%, coal gangue 8%, fluorogypsum 2.0%, volcanic stone 7%, quartz sand 30%, Modified platanus bark 1.3%, fly ash 4%, castor oil 0.04%, polyvinyl alcohol 0.024%, sodium polyacrylate 0.054%, the balance is water;
[0022] Among them, the preparation steps of modified platanus bark are:
[0023] 1) Dry the platanus bark and superfinely crush it into 15μm platanus bark powder for use;
[0024] 2) Immerse platanus bark powder in a sodium hydroxide solution with a mass concentration of 4 times its mass and a mass concentration of 35% for 2 hours;
[0025] 3) Then add 1.5 times the mass of platanus bark powder with silicic acid, and treat it with a microwave with a power of 180W for 3 minutes to obtain a mixed solution;
[0026] 4) Fill the mixed solution with nitrogen to fully deoxygenate, then add ...
