Abstract:

Unexpected interactions between otherwise acceptable ingredients in portland cement

concrete are becoming increasingly common as cementitious systems become more complex

and demands on the systems are more rigorous. Examples of incompatibilities are early

stiffening or excessive retardation, potential for uncontrolled early-age cracking, and unstable

or unacceptable air void systems. Several test methods have been reviewed to assess their

usefulness in early detection of incompatibility, and thus prevent pavement field problems. A

protocol has been developed to allow product manufacturers, concrete producers, contractors,

and owners to monitor materials and concrete systems. The protocol has two phases:

relatively simple field tests to provide early warnings of potential problems and central

laboratory tests to support and confirm the field work.
