Corrosion Behaviors of Rebar in Low Temperature Mortar with Chloride and Nitrite

염화물 및 아질산염을 사용한 저온환경하 모르타르내 철근의 부식특성

In order to examine the possibility of practical at low-temperature environment curable cement mortar with chloride and nitrite as cold resistance admixture for rebar corrosion prevention. As a result, chloride was used using nitrite complex in low temperature environment and corrosion performance of rebar was improved and mortar strength was promoted. The ratio of nitrite than chloride applied more than twice, corrosion of the reinforcing bars will not occur even in low temperature environment, cement hydration reaction will be promoted and mortar will prevent freezing damage.
