| Abstract: | The effect of highly dispersed amorphous aluminum hydroxides on the hydration of Portland cement was studied by the solid-state 27Al and 29Si NMR spectroscopy. It was established that in the presence of aluminum hydroxides the decrease in the setting time of a cement paste is due to rapid formation of ettringite phase, with contribution of admixture material the main and contribution of aluminum-containing phases at this stage insignificant. |
