The influence of three different curing conditions: water (W), steam (S) and autoclave (A) and also steel fibres content on selected properties of RPC was analyzed. The composite characterized by w/s ratio equal to 0.20 and silica fume to cement ratio 20%, depending on curing conditions and fibres content, obtained compressive strength was in the range from 200 to 315 MPa, while modulus of elasticity determined during compression was about 50 GPa. During three-point bending test load-deflection curves were registered. Base on aforementioned measurements following parameters were calculated: flexural strength, stress at limit of proportionality (LOP), stress at modulus of rapture (MOR), work of fracture (WF), and toughness indices I₅, I₁₀ and I₂₀. Both amount of steel fibres and curing conditions influence the deflection of RPC during bending.}, type={Artykuły / Articles}, title={Wpływ wybranych czynników materiałowych i technologicznych na właściwości mechaniczne i mikrostrukturę betonów z proszków reaktywnych (BPR)}, title={The influence of selected material and technological factors on mechanical properties and microstructure of reactive powder concrete (RPC)}, URL={http://www.czasopisma.pan.pl/Content/83770/mainfile.pdf}, keywords={reactive powder concrete, strength, ultra high performance cementitious composites, steel fibres, fibresvolume ratio, curing conditions, fracture energy, fracture toughness index}, }
