PURPOSE: A cement based rapid-hardening adhesive for attaching an autoclave lightweight concrete (ALC) panel of a reinforcing mesh is provided to offer rapid hardening property, high initial strength, high adhesive strength, and low absorption rate after hardening by containing a rapid-hardening inorganic binding material, a polymer, an organic moisturizing agent, and a porous material. CONSTITUTION: A cement based rapid-hardening adhesive for attaching an ALC panel of a reinforcing mesh contains 100 parts by weight of rapid-hardening inorganic binding material, 5-10 parts by weight of hydrophobic revival state powder terpolymer or acrylic liquid polymer, 0.05-0.5 parts by weight of cellulose based and/or starch based organic moisturizing agent, and 0.1-5.0 parts by weight of porous material. The rapid-hardening inorganic binding material contains 20-50 wt% of white or regular cement,, 20-50 wt% of alumina cement or calcium sulfo aluminate (CSA) cement, and 10-30 wt% of anhydrous gypsum, hemihydrates, or chemical gypsum. The porous material is selected from attapulgite, bentonite, cellulose fibers, perlite, or hollow lightweight material. |
