[0051] The preparation method of self-made wear-resistant concrete of the present invention, concrete preparation steps are:
[0052] (1) Mix chitosan, acetic acid and water according to the mass ratio of 1:9:90 to obtain a chitosan solution, and put the obtained chitosan solution into the bottom of stainless steel, with polytetrafluoroethylene insulation on the side wall In the lined container, place the container on a stainless steel low-temperature platform with a temperature of -40°C. After the chitosan solution is completely frozen, it is then freeze-dried to remove water and acetic acid components to obtain a self-made chitosan template; The method controls the growth of ice crystals along a fixed direction, so that chitosan sinks between the ice flakes to form a micron-sized thin layer, and then removes the ice crystals by freeze-drying to obtain a chitosan porous material with a regular layered structure. , since the freeze-drying process directly draws water away in t...
