The invention relates to the technical field of building materials, and discloses ground fine leveling flowing waterproof
mortar and a preparation method thereof, the ground fine leveling flowing waterproof
mortar comprises a dry blend component and a liquid mixing component; the dry blend is prepared from the following components in parts by weight: 350 to 450 parts of ordinary
Portland cement, 50 to 70 parts of
silica fume, 550 to 800 parts of multi-graded
quartz sand aggregate, 20 to 30 parts of redispersible latex
powder, 6 to 8 parts of
calcium formate, 2 to 4 parts of anti-crack short
fiber, 0.5 to 1.5 parts of shrinkage
reducing agent, 0.8 to 1.2 parts of suspending agent, 0.8 to 1.2 parts of thixotropic
lubricant and 0.4 to 0.6 part of low-
viscosity cellulose ether. The liquid mixing component comprises the following components in parts by weight: 3-5 parts of inorganic
silicone oil, 1.5-3.0 parts of a polycarboxylate
superplasticizer and 180-220 parts of mixing water; wherein the multi-graded
quartz sand aggregate is prepared from the following particles in the following particle size range: 150 to 200 parts of 8-12-mesh
quartz sand and 150 to 200 parts of 12-20-mesh quartz sand. By utilizing a rigid
interlocking framework formed by the coarse aggregate and the closest packing effect, the use amount and
porosity of a cementing material are greatly reduced, and meanwhile, the
compressive strength and
wear resistance of the
mortar are remarkably improved.
