• Abstract:
  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 (0.32 to 0.38) concretes at conventional consistencies (slumps of 2 ½ to 3 ½ inches) with conventional equipment and slightly modified procedures. Mixes at greater slumps (3 ½ to 8 inches) are also possible. ; It was the purpose of this study to determine in the laboratory the properties of the Portland cement concrete using super water reducers, with the materials from Louisiana, mixed and evaluated under Louisiana conditions. Information and procedures to be used with these admixtures were explored to permit the use of very low water-cement ratio, air-entrained concrete in highway applications, especially in bridge decks or structures. These aims were part of a laboratory evaluation of a number of mix designs.
