Abstract

The invention relates to environmental-friendly waterproof polymer mortar, which comprises the following components in portion by weight: 50 to 230 portions of low-clinker silicate cement, 200 to 450 portions of quartz sand, 80 to 120 portions of fly ash, 1 to 18 portions of re-dispersible polyethylene vinyl acetate latex powder, 1 to 10 portions of dispersible polyvinyl acetate vinyl versatate latex powder, 0.2 to 0.6 portion of water reducing agent, 0.05 to 0.3 portion of antifoaming agent, and 0.25 to 2.25 portions of polypropylene fibers. A gel material prepared from steel slag, tailings and the fly ash replaces silicate cement and partial aggregate in the prior mortar; the modified waterproof polymer mortar has the advantages of excellent impermeability, good mechanical property and construction property, simple production technology, and easy manufacture, greatly consumes industrial and mining wastes, controls the ecological environment, and lowers the cost; and the product has reliable quality and wide market; and the environmental-friendly waterproof polymer mortar can be popularized and applied in large area.

Description

technical field [0001] The invention relates to a building material, in particular to an environment-friendly polymer waterproof mortar. Background technique [0002] Mortar is one of the most widely used building materials in construction engineering, and it is widely used in masonry and plastering of buildings. In my country's current construction projects, more than 60% of buildings still use wall materials such as bricks and blocks, and the construction mortar used in masonry and plastering construction is still mainly cement mortar or mixed mortar. Ordinary cement mortar is a typical brittle material with high compressive strength, low tensile strength, flexural strength and bond strength, poor toughness and easy cracking. Therefore, it is difficult to meet the requirements of engineering durability and construction efficiency, which largely limits its application in construction engineering. After a lot of experimental research, it is found that adding polymers to or...
