The use of the foam index method in cement grouts for testing the compatibility of cement – superplasticizer – aerating admixture system

The elaboration presents a method of testing the foam index and the associated research problems. Current issues concerning the impact selection of materials on the obtained results were broached. Tests of the foam index conducted in- house were described and results were analyzed. An assessment was made on the basis of the results and the usefulness of the method in terms of testing the compatibility of cement – superplasticizer – aerating admixture system was determined.
