抄録

Roller compacted concrete for pavement is dry concrete and is likely to segregate between the mortar compomponent and coarse aggregate during construction practice. It is important to improve the segregation resistance and to renovate the other performance also. The poly-carboxylate type air-entraining high range water-reducing admixture (AHW) mixed with acrylic acid type viscous agent at the percentage of 5 to 20% by weight of AHW was produced for this experiments. Some properties of the concrete added this admixture were compared with the case of using conventional water reducing agent and following results were obtained.<BR>1) Much of unit water content was reduced for a given consistency and the segregation resistance was improved sufficiently.<BR>2) Frost resistance could be improved by adding supplementary air-entraining agent.<BR>3) Drying shrinkage was reduced and bending strength was increased at the age of 1 to 28 days.
