In order to study the influence of hybrid fiber on the frost resistance of lightweight aggregate concrete, the impermeability and frost resistance of six kinds of fiber lightweight aggregate concrete (ceramic fiber and steel ceramic fiber) were tested. The research shows that adding proper amount of hybrid fiber into lightweight aggregate concrete can improve the impermeability of lightweight aggregate concrete, reduce the mass loss rate of concrete and improve the compressive strength loss rate after freezing and thawing, and play a favorable role in enhancing the durability of lightweight aggregate concrete; When the amount of hybrid fiber is too much, it will lead to the increase of harmful pores in the concrete matrix, which is not conducive to the impermeability of lightweight aggregate concrete.
