The objective was to test the efficiency of technical calcium nitrate (CN) as a set accelerator for different cements at low temperatures (5–7 °C). The applied dosages were 0.00, 1.55, 2.32, 3.10, 3.86 and 7.73 % CN of the cement weight, corresponding to 0.00, 1.00, 1.50, 2.00, 2.50 and 5.00 % NO3,...
