✦ Synopsis

This paper deals with the effect of two different superplasticizers (Mighty and Melment) on the air-void system parameters produced by two different airentraining 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.

The reduction in mixing water of the concrete, caused by the addition of a superplasticizer, depends also on the type of cement used. Superplasticizer based on naphthalene sulfonated polymer acts much more effectively on cement containing gypsum dihydrate than on that containing calcium sulfate hemi
