A Experimental Study on the Change of Concrete Strength Characteristics which is dried by the Heat |
| Abstract |
After the mass concrete construction such like automic power-plant is complicated resently more and more with large scale. At the case of it to be applied heat, the strength charactics of it is guessed to be influenced so much by the moisture content to the mass concrete. In this study, therfore, there is an experiment purpose to obtain the basic data to be seen when test-piece examined into the func-tional relation between the moisture content and the strength chractics of it at a temperature of 20 C-175 C. According to the experiment result, the compressive strength and the modulus of elasticity are all influenced much more by the factor of the moisture content than that of heat temperature, and this influence was largely worked at the modulus of elasticity more than at the compressive strength.Per as the water content's decrese of 1%, the modulus of elasticity of the mass concrete was brought about the decrease of 2.5% or so. Aiso, it have to be considered content quantity for the calculation formula which can be assumed the modulus of elasticity. |
