At the Waterways Experiment Station, four high-range water-reducing admixtures were tested for compliance with the requirements for water-reducing admixtures given in ASTM: C 494-71. None passed the test for frost resistance; all met all other requirements.
Editor: V.M. Malhotra
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.
Mario Collepardi and Mario Corradi
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.

A superplasticizing admixture of the sulphonated melamine formaldehyde condensate type was tested in the laboratory for its effect on concrete mixes with a nominal slump of 3 in. (75 mm) and 415 kg/m3, respectively). A total of nine mixes were prepared. All mixes contained an air entraining admixture.
Richard C. Mielenz and James H. Sprouse
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.
