Abstract:
Presents basic principles of proportioning shrinkage compensating concrete mixtures using currently available expansive cements and relates them to proportioning mixtures using Type I cement. Properties which are common to all expansive cements and their differences are discussed. Conditions under which slump loss may occur when using some expansive cements are reviewed and methods for adjusting mixing water to compensate are given. Recommendations for the use of admixtures are made and importance of proper curing and adeqate internal restraint are discussed briefly.
