In　order　to　investigate　the　durability　of　coal　gangue　aggregate　concrete,　related　tests　of　durability　of　coal　gangue　concrete　from　macroscopic　and　microscopic　are　measured　in　this　paper.　Results　show　that,　all　coal　gangue　are　non-active　aggregate.　Within　a　certain　range,　coal　gangue　will　not　significantly　reduce　the　impermeability　of　concrete.　With　the　increase　of　coal　gangue,　mechanical　performance　of　coal　gangue　concrete　has　not　been　reduced,　but　frost　resistance　of　concrete　has　been　significantly　reduced　in　this　paper.　Spacing　factor　of　air　void　can＇t　be　accurately　assessed　frost　resistance　of　coal　gangue　concrete,　water　absorption　of　aggregate　is　another　important　factor.　The　interface　structure　between　aggregate　and　hydrates　of　coal　gangue　concrete　is　different　from　ordinary　concrete.　For　the　coal　gangue　aggregate　used　in　cement　concrete,　this　study　proposes　four　indicators:　coal　gangue　content,　water　absorption,　crushing　index　value,　flaky　and　elongated　aggregate　content.
