<p>PROBLEM TO BE SOLVED: To obtain an adhesive for mortar concrete with which the strength of adhesion of a porous concrete plate and ordinary concrete plate can be made greater and a large-sized concrete flat plate usable adequately as a flat plate for precast pavement, or the like, can be manufactured. SOLUTION: This adhesive for the mortar concrete includes 100 pts.mass cement or powder mixture containing the cement, 0 to 300 pts.mass fine aggregate, 0.1-2.0 pts.mass (in terms of solid content) water-reducing agent and 10 to 30 pts.mass water. The adhesive for the mortar concrete preferably contains <=5.0 pts.mass expansion additive and further preferably contains <=2.0 pts.mass retarding agent.</p> |
