This work was carried out in an attempt to widen the potential use of polymer concrete in the construction industry. The concept of ultimate strength limit state in design of PC is furnished on the bases of the mechanical properties found experimentally. Five distinct PC grades of polyester resin concrete that might fairly represent average properties of PC were proportioned after studying the potential optimization techniques of resin mortar mix design for which a mix design chart is developed. Most of the mechanical properties of the five PC grades were investigated under short term conditions. The stress block shape and parameters of the compression zone in flexure are explored. Empirical and theoretical values for the stress block parameters are developed. These values were used in full scale structural applications, a beam and a column for each PC grade, and were found to be satisfactorily accurate. The concept of specific reinforcement ratio to be used with high tensile steel reinforcement which has no definite yield point is established. The effects of rate of loading and sustained load were studied. Expressions for long-term ultimate compressive strength, long-term modulus of elasticity, sustained strength, macrocracking strain and creep strains are given for various PC grades. Ultimate strength design procedures and their design charts for various loading conditions and relevant values of capacity reduction factors are suggested on the basis of the structural performance of PC under short-term and long-term conditions.
