Concrete property can not be defined only by compressive and tensile strength, but temperature property of concrete is one of the most important factors under the condition of various limitation. Therefore it is considered to find out any change of concrete strength property due to temperature such as heat. 1) Aluminum materials are not effective to improve concrete strength than normal one. 2) Strength of molds heated with three hundreds degree was ten percent decreased in comparison with normal one, thirty five percent decrease for six hundreds degree, and eighty five percent decrease for nine hundreds degree centigrade. 3) Strength of molds mixed with aluminum material was fifteen percent decreased for one percent mixing proportion. Thirty percent decrease for one point five percent mixing proportion, forty five percent for two percent proportion, eighty percent for five proportion.
