Abstract:Unexpected interactions between otherwise acceptable ingredients in portland cement concrete are becoming increasingly common as cementitious systems become more and more complex and demands on the systems are more rigorous. Such incompatibilities are exhibited as early stiffening or excessive retardation, potential for uncontrolled early-age cracking, and unstable or unacceptable air void systems. A number of test methods have been reviewed to assess their usefulness in detecting incompatibility early to help prevent problems with pavements in the field. A protocol has been developed to allow product manufacturers, concrete producers, contractors, and owners to monitor their materials and concrete systems. The protocol is phased to allow relatively simple field tests to provide early warnings of potential problems and then central laboratory tests to support and confirm the field work.
