Abstract
Corrosion of reinforcement is the main factors affecting the durability of reinforced concrete in the world which lead to the failure of structures of reinforced concrete buildings. In this research, mixed brucite(Mg(OH)2) into ordinary portland cement paste in ratio of 5, 10 and 15% as a kind of CO2 fixation material. Samples were exposed to an accelerated carbonation enslavement of 20% CO2 concentration,60% relative humidity, and a temperature of 20℃ until tested at 3d,7d,14d and 28d. After 28d CO2 accelerated curing, in the paste containing MH megnesian calcite was found by XRD and SEM-EDX. Meanwhile, paste containing Mg(OH)2 exhibit the better pore distribution than ordinary portland cement paste and relatively good compressive strength.
