AIR ENTRAINMENT IN NO-SLUMP MIXES

Open publisher page 11 citations

Abstract

Over the last few decades, the use of air entrainment has been shown to be extremely beneficial for conventional concretes. In addition to improving the workability of the fresh mix, there exists overwhelming laboratory and field data indicating that the entrainment of a sufficient number of spherical air bubbles has a beneficial influence on the frost durability of hardened concrete. The results of a laboratory investigation of the mechanisms of air entrainment in no-slump concrete mixes are reported herein. This study was carried out as part of research aimed at improving the frost durability of RCC pavements and prefabricated concrete paving blocks. The results obtained for mixes prepared under full-scale production conditions will be the subject of a subsequent publication.
