ANALYTICAL STUDY ON ESTIMATION OF STRESS-STRENGTH RATIO FOR CONCRETE WITH HIGH CONTENT OF ADMIXTURE

Concrete with high content of admixture is effective in reducing the stress-strength ratio because of the low heat generation associated with the hydration reaction. However, concrete with high content of admixture is out of the scope of general stress-strength ratio estimation formulas. Therefore, the authors conducted an analytical study and developed a stress-strength ratio estimation formulas for concrete with high content of admixture. Case studies using this estimation formula showed that the estimated values can be evaluated safer than the analytical values, and that concrete with high content of admixture is more applicable to massive concrete.
