FACTORS AFFECTING REAL LIFE PERFORMANCE OF CONCRETE IN BRIDGE SUB-STRUCTURES IN THE UK. THE UNITED STATES STRATEGIC HIGHWAY RESEARCH PROGRAM. SHARING THE BENEFITS. CONFERENCE ORGANIZED BY THE INSTITUTION OF CIVIL ENGINEERS IN COOPERATION WITH U.S. STRATEGIC HIGHWAY RESEARCH PROGRAM, 29TH-31ST OCTOBER 1990, TARA HOTEL, KENSINGTON, LONDON

From 17 bridges, 50 small areas of concrete were selected for detailed investigation to find what particular difference of concrete quality had resulted in some having failed to protect the reinforcement from corrosion whilst others had proved adequate. The age range was 11 to 68 years. Site measurements included carbonation depth, cover and chloride profiles together with resistivity and half-cell potentials. Concrete quality was assessed from core samples and included gas permeability, absorption, porosity and cement content. The results showed some correlation between the different parameters and with durability, but also showed great field results and suggests that fundamental laboratory studies may well be a more effective way to investigate durability.
