Abstract:
Adjustment of Entrained Air at the Job Site: Does ACI allow the addition of air-entraining admixtures at the job site to increase air content of concrete mixtures that do not meet specified levels?
Adjustment of Slump at the Job Site: What is the acceptable practice for adding water or water-reducing admixtures to concrete that has a slump below the specified minimum at the job site?
