<p>PROBLEM TO BE SOLVED: To obtain an adhesive useful for fixing and joining a concrete-base structural member, a mineral-base structural member, etc., by kneading a first specified powder and an admixture comprising a second powder with water glass. SOLUTION: This adhesive is obtained by kneading a first powder containing at least SiO2 , CaO, an iron oxide, a titanium oxide and Al(OH)3 , preferably in an amount of 30-50wt.%, and a second powder serving as an admixture and preferably comprising silica sand, preferably in an amount of 30-50wt.%, with water glass preferably in an amount of 10-30wt.% (the total of these three components being 100wt.%). The first powder preferably comprises a mixture of 30-50wt.% slug at least containing at least 10wt.% SiO2 , at least 25wt.% CaO, at least 5wt.% iron oxide and at least 0.2wt.% titanium oxide and having a particle diameter of 120μm or smaller, 30-50wt.% silica powder having a particle diameter of 0.1-1μm, and 10-30wt.% Al(OH)3 having a particle diameter of 0.5-20μm.</p> |
