Zusammenfassung:	PURPOSE:To obtain MMA resin concrete having high flexural strength, comprising a MMA resin concrete layer specifying the maximum diameter of aggregate, voids and thickness, respectively and a MMA resin concrete layer having larger maximum diameter of aggregate than the maximum diameter of aggregate. CONSTITUTION:A molding of MMA resin concrete molded article consisting essentially of an aggregate and a polymethyl methacrylate is constituted in the following way. Namely, a MMA resin concrete layer (layer A) using an aggregate having 0.5-2.0mm maximum aggregate diameter and voids epsilon obtained by the formula of =3mm maximum diameter of aggregate is prepared. A MMA resin concrete molding of double layer structure of having excellent flexural strength, consisting of the layer A and the layer B, is obtained. In the case, the thickness of the layer A must be 0.2-0.7 total thickness. The MMA resin concrete molding shows excellent characteristics of >=400-500kg/cm flexural strength.
