Abstract

The invention relates to quick-setting cement mortar and a preparation method thereof. The quick-setting cement mortar is concretely prepared from materials such as sulphate aluminium cement, styrene butadiene rubber emulsion, polyurethane emulsion, a water reducer, trolamine, droxyethylcellulose, fibre, river sand, water and the like according to a certain weight ratio. The quick-setting cement mortar has the characteristics of quickness in setting at normal temperature, high strength in the early stage, crack resistance, good durability and the like, can be widely applied to the fields such as embankment reinforcement, channel impermeability, soil and water conservation, side slope protection, quick repair of concrete road surfaces, and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a quick-drying cement mortar for building engineering and a preparation method thereof. Background technique [0002] Sulphoaluminate cement mortar has outstanding quick-drying and early-strength characteristics, and has properties such as volume expansion, corrosion resistance and low alkalinity, and is usually used to manufacture anti-corrosion and impermeable materials, rapid repair materials, etc. However, anti-corrosion, anti-seepage and repair materials made only of sulphoaluminate cement mortar have low later strength, are easy to shrink and crack, and the porosity of the hydration hardened slurry is large, so the corrosion resistance cannot meet the engineering requirements. Adding a small amount of organic polymers and fibers in cement mortar can effectively reduce the pores in the cement mortar, so that the cement mortar can obtain high density wi...
