As an important building material,the durability of concrete is an important factor affecting its service life.Through testing the carbonization performance of common types of concrete,the results show that:the admixtures reduce the carbonization resistance of concrete,and the slag powder has a relatively good ability to maintain the carbonization performance of concrete.The improvement effect of high performance water reducing agent on the carbonization performance of concrete is better than that of high efficiency water reducing agent.The extension of concrete standard curing age will increase the quantity and type of hydration products in concrete,thus enhancing its carbonization resistance.
