This study investigated the performance of both concrete and grout mixtures with and without self-consolidation in addition to various types of viscosity ...
However, it was the French engineer Hennebique who had the greatest influence on early reinforced concrete bridge construction. Examples of Hennebique's work are his bridge built at Chatellerault in France in 1899, which is three arch spans of 131, 164, and 131 ft (40, 50, and 40 m), each with rise/span ratios of ∼0.1, and his Risorgimento Bridge built over the Tiber in Rome in 1911, which ...
