A Study on Increasing Durability of Concrete Curbing Block
초록
Concrete curbing blocks have been widely used in construction of roadways because they are easy too manufacture and cheap. But recently stone curbs are taking away the role from concrete curbs, because the durability of concrete curbs is inferior to stone curbs. Especially freeze-thaw effect on concrete is the most important cause that damages concrete curbs. The aim of this study is to increase the durability of concrete curbs. The concrete curbs that have been manufactured are extremely damaged below 60 cycles of freeze-thaw, but the ones that was manufactured with admixtures that entrains air are maintaining over 87% of relative dynamic modulus.
