Abstract:

In this research, twenty batches of concrete with six different mixture proportions were tested with VERIFI to evaluate 1) accuracy

and repeatability of VERIFI measurements, 2) ability of VERIFI to adjust slump automatically with water and admixture, and 3)

effects on concrete properties when water and admixture are added continuously during transit instead of adding whole at the plant or

jobsite. For each batch, concrete was sampled every 30 minutes up to 90 minutes and tested for slump, temperature, air content, unit

weight, water content, bleeding (select batches), and rheology (select batches). Cylindrical concrete specimens were cast at 90 minutes

and were tested for compressive strength at 3 and 28 d (or 3 and 14 d for IDOT mixes).
