Original Abstract

The paper is focused to evaluation of mechanical fracture properties of hardened cement mortars with a partial replacement of Portland cement reactive admixtures in relation to the microstructure through the size and content of pores. In mortars cement was partially replaced by admixtures that contain different amounts of amorphous SiO2. Three-point bending test on beams with a central edge notch were performed. Mechanical fracture properties of mentioned cement-based composites covered elasticity modulus, effective fracture toughness and specific fracture energy.
