Automated Foam Index Testing: A Quantitative Approach to Measure the Capacity and Dynamics during Air Entraining Agent Uptake


It is shown that quantitative uptake capacities and interaction dynamics of air entraining agents (AEA) with combustion fly ash and cement-ash mixtures are possible to obtain through the automated acquisition of foam index values. Automation includes adding controlled amounts of water and AEA, measuring bubble stability after intense agitation of the… (More)
