Abstract

Paper deals with utilization of fine ground ceramic powder as a supplementary cement addition. Present work follows previous research focused on the basic physical and hygric properties of cement composites with ceramic powder application. Present work introduce rheological, mechanical and fracture properties of cement pastes investigated during maturation at time 7 days. Presented data are added by results of pore characteristic having essential impact to final properties. Obtained data confirm previous assumption of retarding of hydration process, but final fracture properties indicate increased durability of cement pastes with fine ceramic powder addition.
