Underspanned Bridge Structures in Reactive Powder Concrete (RPC)
Adapted structures must be developed so that modern reactive powder concretes (RPC) can be incorporated into new construction projects in an efficient and logical way. The steps of this development, from the analysis of the material characteristics, to the determination of the structural requirements, to the arrival at an appropriate adapted structure are described. An Outlook on the developmen...
متن کاملHigh Performance Reinforced Concrete Beams made with Sandstone Reactive Aggregates
An investigation on the flexural behaviour of reinforced high performance concrete (HPC) has been conducted. Crushed sandstone known as reactive aggregate was used for both fine and coarse aggregates. In addition, mineral admixtures such as silica fume and fly ash combined with superplasticiser was used. The beams were made with concrete having compressive strength in the range of 74 88 N/mm 2 ...
متن کاملInfluence of Ultrafine 2CaO·SiO2 Powder on Hydration Properties of Reactive Powder Concrete
In this research, we assessed the influence of an ultrafine 2CaO·SiO₂ powder on the hydration properties of a reactive powder concrete system. The ultrafine powder was manufactured through chemical combustion method. The morphology of ultrafine powder and the development of hydration products in the cement paste prepared with ultrafine powder were investigated by scanning electron microscopy (S...
متن کاملModelling the loss of steel-concrete bonds in corroded reinforced concrete beams
The existing stochastic models for deterioration of reinforced concrete structures is extended by adding modelling of “loss of bond” due to corrosion between the reinforcement bars and the surrounding concrete.
متن کاملFlexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling
The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...
