Amorphous nano-silica (nS) particles (0–2.5wt%) by cement were incorporated in cement pastes and mortars, and their effect on the fresh state behaviour was analysed. Rheological tests showed that after 75min from the mixing start, the mortar having 2.5wt% nS shows insufficient flowability to allow i

The results of a study on the influence of temperature on the compressive strength of mortars and concrete are described. Identical specimens were exposed to temperatures of 25Β°C, 35Β°C or 50Β°C for sustained periods of up to 300 days. Besides ordinary Portland cement (OPC), blends of OPC with powdere
