Abstract:
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.

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.

The trends in the rate of slump loss in superplasticized concrete due to the variation in temperature, concrete consistency, cement content and type, time of conventional admixtures in conjunction with the superplasticizer were determined.

Four commercial high-range water-reducing admixtures based on naphthlanene-sulfonic acid-formaldehyde condensation products and two commerical admixtures of this type based on melamine-sulfonic acid formaldehyde condensates were investigated to determine their effect on the air-void system in fresh and hardened concrete.

An investigative program was conducted at the TVA Laboritories to determine the relative performance of several super water reducers. Both plain and fly ash concrete mixes were included to check the compatiabiilty of pozzolans with superplasticizers.
