All the above products couldn't contend with lime/pozzolan concretes due to quickly-location (giving inadequate time for placement) and low early strengths (requiring a hold off of numerous weeks just before formwork could be eradicated). Hydraulic limes, "normal" cements and "synthetic" cements all depend upon their belite material for energy progress. Belite develops energy slowly and gradually. Mainly because they were being burned at temperatures below 1250 °C, they contained no alite, which happens to be answerable for early energy in modern day cements.
