| Abstract |
Previous researches for increasing the durability of concrete structures examined the characteristics of concrete using glycol ether admixture, and determined the optimal addition rate and evaluated durability of concrete.However, today’s ready mixed concrete uses various industrial byproducts in order to improve the performance of concrete, and the quality of concrete changes depending on the addition of glycol ether admixture and curing condition. Considering this, we need to understand the characteristics of curing methods according to field condition. Thus, the present study evaluated the effects of replacement with fly ash as a binder and curing conditions (temperature and humidity) on the performance of concrete, and obtained data from a mock?up test for the practical use of concrete containing glycol ether admixture. According to the results of this study, the concrete showed resistance performance of around 30% to carbonation and around 40% to drying shrinkage. In addition, as for resistance to freezing and thawing, the relative dynamic modulus of elasticity was over around 85% through atmospheric curing. These performances prove the effect. |
