Abstract:An organic shrinkage reducing agent consists mainly of lower alcohol alkylene oxide adducts. It has a great effect of reducing drying shrinkage. There are few studies on durability of concrete with the shrinkage reducing agent. This paper presents the results of a study on durability of concrete with the shrinkage reducing agent exposed to outdoor in a cold district for 10 years. Flexural strength, compressive strength and dynamic modulus of elasticity of concrete with the organic shrinkage reducing agent has not shown any problems as same as concrete without the agent even at the age of 10 years. Therefore, in a cold environment, it is thought that concrete with the shrinkage reducing agent, which contains a sufficient air content, will not be deteriorated by freezing and thawing action.
