Abstract

²⁹Si MAS-NMR measurements of cement have been used to follow the hydration process in cement pastes. Samples prepared using a w/c ratio of 0.45 and type I cement have been cured at temperatures over the range 20 to 55°C with curing times of 3 to 28 days. Compressive strength values for samples subjected to the same time/temperature curing regime were also obtained. The compressive strength is found to show a linear dependence on hydration as characterized in terms of the NMR Q⁰, Q¹ and Q² silicate polymerization states. Solid state ²⁹Si NMR measurements appear promising as a means of monitoring cement/concrete strength.
