Abstract

One of the most accepted thermal storage system of solar thermal power for balancing energy considers the use of cementitious/concrete materials. We report the preparation of nano-SiO2 optimized aluminate cementitious pastes as thermal storage materials with mass fractions of 0, 5, 10 and 15% Cu powders and the influence of Cu additives on thermal and mechanical properties of the composite pastes. The specimens were heated at 105, 350, and 900 °C. When 15% Cu powders were added, the properties of the composite pastes were significantly modified at corresponding heat-treatment temperature. This paper also deals with the heat evolution of the composite pastes in the early 48 h, observing the double effects of nano-SiO2 and Cu powders in the hydration process.
