In most cases, despite the very large variety of cements,
admixtures, supplementary cementitious materials (SCM's) and
conditions encountered by concrete producers, predictable performance
can be achieved, otherwise the concrete industry would suffer
far more problems than it does. However, in some cases unexpected
slump loss, excessive fast or slow set, and/or poor or absent strength
development can occur. The concrete industry has had an on-going
challenge to minimize these unexpected events, which can cause
major disruptions of construction schedules.
