EFFECT OF SUPERPLASTICIZERS ON THE ENTRAINED AIR-VOID SYSTEM IN CONCRETE

This paper deals with the effect of two different superplasticizers (Mighty and Melment) on the air-void system parameters produced by two different air-entraining agents (NVR and Darex), when the superplasticizer is added some 40 minutes after the concrete has been batched and mixed. A significant drop in air content was observed with corresponding reductions in total air-void surface areas and increases in air-void spacing factors. (Author abstract)
