Abstract:
SP62 This collection of 20 papers represents the most comprehensive work to date on one of the industry’s newest developments-the high-range water-reducing admixtures called superplasticizers. In clear, understandable terms, it answers important questions and collects information from an international symposium on the applications, advantages, and limitations of superplasticized concrete. This fact-filled volume covers such topics of vital interest as what superplasticizers mean to you and the concrete industry. How superplasticizers can help you. And under what circumstances are they at their best. In-depth case histories of current world-wide applications show you how superplasticizers actually work.

This work presents the results of an experimental investigation to develop equations for estimating the potentional strength, modulus of elasticity, dry unit weight and pulse velocity of both regular and superplasticized concrete by using the Accerlerated Curing Method recommend by the American Society for Testing and Materials. A series of 24 concrete mixes (12 control and 12 superplasticized) were tested. The variables used were water-cement ratio, the initial temperature of concrete and air content.

Functional water-reducing admixtures provided water reduction up to 30 percent in portland cement-fly ash concretes with binder contents of 740-770 pcy (440-455 kg/m3), calcareous sand, and dolomitic limestone coarse aggregates.

Two superplasticizers, both based on naphthalene-sulphonated formaldehyde condensed resin, were used to prepare concretes with three types of portland cement, two cement contents, two types of aggregates, cured at room temperature and steam cured.
