Abstract:A laboratory study on the durability of OPC and trass-OPC mortars and concretes is presented. A natural pozzolan of volcanic origin obtained from the Demavend area in Iran and known as "trass" is used to substitute 20 percent of the OPC content of mortar and concrete. The performance of the material is evaluated by measurements of total porosity. Pore-size distribution and permeability are given in relation to their response to aggressive chloride and sulfate concentrated solution, and also CO 2 gas. The carbonation data is used to formulate a performance-time function, which is proposed as a model to assess durability of the mortars and concretes.
