For the purpose of making clear strength and elastic characteristics of massive concrete structures in reactor buildings subjected to temperature of 65℃ from on face, We made experiments and studied by the use of imitative structures supposed real structures and test pieces. The results obtained are summarized as follows : 1) In the factors that affect strength and elasticity of test pieces dryness of heating has more effect than temperature of heating and elasticity is more affected than strength. 2) The moisture in the imitative structures subjected to high temperature from on side has tendencies to low moisture at heating face and open face, high moisture at position near open face. 3) The strength and elasticity in the imitative structures after heating for three months rise rather than drop compared with that at the test pieces just before heating. It is possibible to infer the strength in the imitative structures subjected to high temperature from one side, with the use of test pieces. 4) In case of making an inference by the medium of moisture, the strength and elasticity after heating for a year will be reduced within four percent compared with that after heating for three months.
