2results about How to "Fast hardening" patented technology

This invention relates to a nano-metakaolin-modified hydraulic lime-based composite material and its preparation and application. The composite material comprises natural hydraulic lime and nano-metakaolin dispersed in the natural hydraulic lime, wherein the mass ratio of natural hydraulic lime to nano-metakaolin is (60-90):(10-40). The nano-metakaolin-modified hydraulic lime-based composite material of this invention exhibits controllable dispersibility and fluidity in the slurry after mixing with water. It also demonstrates good rock compatibility, low soluble salt content, controllable curing time, suitable post-curing strength, low permeability, and low shrinkage and expansion rate. The presence of a repair agent can specifically enhance the additional protective performance of the reinforcement material. It possesses high applicability, safety, and durability for the protection of stone cultural relics, without causing derivative damage.

This utility model discloses a construction structure for a dry-installation, quick-setting waterproof integrated panel for bathrooms. It includes, sequentially arranged on the floor slab, an interface agent layer, a quick-drying thick self-leveling mortar layer, a JS waterproof layer, a waterproof backing board layer, a tile adhesive layer, and an anti-slip tile layer. The quick-drying thick self-leveling mortar layer is a building material composed of ordinary silicate cement, aluminum sulfate cement, calcium oxide, fine perlite, and dried river sand. The quick-drying thick self-leveling mortar layer is poured onto the interface agent layer, and the JS waterproof layer is applied onto the quick-drying thick self-leveling mortar layer. The waterproof backing board layer is assembled from extruded polystyrene boards and is fixed to the JS waterproof layer using studded adhesive strips. This application uses the quick-drying thick self-leveling mortar layer and the waterproof backing board layer as leveling layers, featuring fast construction and fast hardening speed. Initial setting occurs within two hours after construction, and people can walk on it after four hours. The leveling layer is then formed by bonding the waterproof backing board layer. The construction is simple, convenient, and efficient.
