This test follows an ASTM standard test protocol and is very simple to conduct. For the first time, the results of direct measurements of volume reduction in CMB were obtained. These results confirm that the higher water–to–cement ratios in CMB lead to less efficiency of the hydration reactions at early age. This method can be used routinely to assess and understand the short term hydration processes in CMB.
