Neural networks have recently been broadly used in civil engineering applications due to their versatile capability as a simulator for the complex behavior of many problems (Adeli 2001). Compressive strength of cement mortar is mainly affected by water/cement ratio and aggregate/cement ratio. Recently, high performance concrete has been actively studied, however it is more difficult to predict ...

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...
