Abstract：Inorder to further explore the efectofbagasse ashon the mechanicsdurabilityofconcrete，diffrent quality of bagasse ash was mixed into concrete according to a certain proportion， the slump，compressive strength，chloride ion penetration frost resistance test werecarried out.The microscopic test method was used to further explore the influence mechanism of bagasse ash on concrete.The results show thatthe slumpof concrete decreases with the increase of bagasse ash content， the minimum slump is 84 mm.The compressive strength increases first then decreases， the compressive strength reaches the maximum of 96 MPa when A4=20% The incorporationof bagasseash can efectively improve the durabilityof concrete，thechloride ionresistance frost resistance are improved， the harmful pores，more harmful pores porosity in the concrete can be reduced， the harmless pores lessharmful pores are increased，thereby improving the internal pore structure of concrete improving the mechanical durabilityof concrete.The test results can provide reference for the application of bagasse ash concrete.
