Abstract

The invention relates to cement base-free waterproof anti-cracking mortar and a production method thereof. The cement base-free waterproof anti-cracking mortar is prepared from an inorganic gelling material, an organic additive, water-proofing powder and fine sand of 70-140 meshes. The cement base-free waterproof anti-cracking mortar comprises, by weight, 30-50% of the inorganic gelling material, 50-70% of the fine sand, 2-4% of the organic additive and 2.4-4% of the water-proofing powder. The inorganic gelling material comprises, by weight, 75-85% of an active admixture and 15-25% of an alkaline exciting agent. The active admixture comprises industrial waste such as fly ash, steel slag powder and ore slag powder. The alkaline exciting agent is a mixture of cement, lime, gypsum and anhydrous sodium sulphate. The organic additive is a mixture of cellulose ether, redispersible polymer powder, wood fibers and polypropylene short fibers and a weight ratio of cellulose ether, redispersible polymer powder, wood fibers to polypropylene short fibers is 4.5-6.5%: 60-80%: 7-10%: 2-4%. The production method comprises the following steps of proportioning and metering the above raw materials according to a preset ratio, carrying out mixing and carrying out packaging. The cement base-free waterproof anti-cracking mortar has low production energy consumption, a low cost, good crack resistance and good waterproofness.
