PROBLEM TO BE SOLVED: To provide a method for constructing a housing foundation structure, which has excellent workability over a wide range of temperature and allows a favorable surface of a hardened body to be formed; and a housing foundation structure constructed by the method.;SOLUTION: A method for constructing a housing foundation structure comprises the steps of: installing a formwork 13 for forming the housing foundation structure, arranging a steel bar 14 in the formwork 13, forming a substrate concrete 16 in the formwork 13, and casting a highly fluidized mortar slurry 17 containing a highly fluidized mortar composition and water on the top face of the substrate concrete 16 so as to form a hardened mortar body 18 on the top face. The highly fluidized mortar composition contains Portland cement, inorganic powder, inorganic expansion material, fine aggregate, and a thickner. The 2 wt% aqueous solution of the thickener at 20°C has a viscosity of 10 to 2000 mPa s.;COPYRIGHT: (C)2013,JPO&INPIT
