Influence of Different Admixtures on Hydration Process and Mechanical Properties of Cement Paste
Original language description
Sustainable developments requires massive use of recycled materials but recycling of fines part of cementitious materials, which mostly composed of cement paste, proves to be very complicated. Therefore reactive properties of recycled concrete powder due to presence of non-hydrated cement grains are investigated. To eliminate influence of larger nucleation area (caused by presence of fine particles) on hydration process the inert micro-milled silica sand was used to comparison. Calorimetric measurement proves the presence of exposed non-hydrated particles in recycled concrete powder that can react again. But lower density of old cement paste in RCP overweight the mentioned potential of recycled concrete powder and mechanical properties are decreased compared with reference cement paste and cement paste with micro milled silica sand.
