There is no doubt that oil products have a clear effect on all materials, especially building materials, including concrete, so we must strive to improve the properties of chemical resistance and mechanical resistance in order to reduce the impact of oil, making it serviceable. Where it was studied how to reinforce concrete with wood ash associated with waste coming out from the towers of power plants and at specific rates that do not exceed 3%, making it more resistant than reference concrete as shown by the results when measuring compressive strength and tensile split resistance. The negative effects of regular oil products in concrete were that the addition of ash reduced these effects. in different oil products and outdoor the higher value of compressive strength in outdoor with wood ash 23 MPa, splitting tensile strength test value is 5.8Mpa where the negative effect of oil products (various kinds) emerged as it was the deadliest effect of casaewil.
