Design and Test Properties of Super Water Reducers in Portland Cement Concrete

摘要

Recently, new concrete admixtures (super water reducers) have been developed and marketed by private industry. These admixtures permit the mixing and placement of very low water-cement ratio concretes at conventional consistencies with conventional equipment and slightly modified procedures. It was the purpose of this study to determine the properties of this type of concrete evaluated under Louisiana conditions and to look into the use of these admixtures in air-entrained concrete for structural applications. These aims were part of a laboratory evaluation of a number of mix designs. Guidelines for the use of these admixtures were written.
