PROBLEM TO BE SOLVED: To provide a construction/civil engineering panel which is lightweight, highly strong, excellent in durability, free of degradation in strength and of deformation due to water absorption and ambient temperature fluctuation, excellent in workability like nailing etc., and usable as a concrete form, a floor, a wall, a ceiling, etc. of a building. SOLUTION: The construction/civil engineering panel comprises a panel body 2 formed of lightweight cement having a specific gravity falling within the range of 0.5-1.0. The panel body 2 comprises a porous compact 8 obtained by filling, curing and solidifying a kneaded substance in a hermetically sealed cement form of which the kneaded substance is prepared by kneading cement, water, reinforcing fibers and the foam prepared by prefoaming a foaming agent. The porous compact 8 contains the reinforcing fibers 7 and the foam in a dispersion state. The surface of the panel body 2 is integratingly covered with a surface reinforcing sheet 4 made of woven cloth or unwoven cloth. COPYRIGHT: (C)2009,JPO&INPIT
