reactive powder concrete (rpc) is an ultra high performance concrete which has superior mechanical and physical properties. the rpc is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (w/b) (less than 0.20) and super plasticizer (sp). the rpc has a very high compressive and tensile strength with better durability prope...

The corrosion resistance of ultra-high performance concrete (UH) made with different fibre contents and under distinct curing conditions was studied. No signs carbonation were observed after 1 year accelerated testing (3% CO2). fibreless UHs’ electrical resistivity above 5000 Ω·m, although these values 2-fold higher than a UH 1% fibres approximately 5-fold 2% fibres. Concrete to chloride penetr...
