PROBLEM TO BE SOLVED: To provide a multilayer structure porous concrete effectively utilizing characteristics such as adsorption, water absorption, humidifying property or the neutralization of water which char coal or the like made from a crushed and size adjusted ligneous waste material as a raw material or scallop shell has and reasonably obtained to be lightweight with the efficiency in the construction on site at a low cost. SOLUTION: The multilayer structure porous concrete is formed by adding aggregate composed of the crushed and size adjusted char coal or the like or the scallop shell respectively into a binder material composed of cement, water and an admixture of an inorganic compound or the like, mixing them, pouring them into a framework in a prescribed order, hardening and integrating to be layered in multistage.
