The strength assessment of existing reinforced concrete structures is challenging where deterioration and detailing deficiencies are present. The anchorage of the internal steel reinforcement can be critical under particular confinement conditions of

Salt water exposure conditions relevant to carbon-fibre-reinforced polymer (CFRP) prestressed concrete structures in marine environments are investigated. The diffusion into relatively small diameter CFRP tendons can be a lengthy process so the predi

The geometric shapes and materials commonly used in conventional steel-reinforced concrete can result in a high wastage of cement that in many cases is not necessary to deliver the required load-bearing capacity. Textile-reinforced concrete (TRC) all

Carbonation is both one of the primary deterioration mechanisms in reinforced concrete structures and a method for sequestration of environmental CO2. Owing to rising atmospheric CO2 concentrations, understanding concrete carbonation is of increasing

Many analytical tools for the prediction of the shear capacity of reinforced concrete beams do not explicitly predict the crack kinematics that reflect the actual cracking behaviour. As a result, most models require experimentally measured crack patt

Specimens of two concretes with different water/cement ratios are subject to various curing and pre-conditioning regimes before being placed in accelerated carbonation conditions. Their carbonation depths are revealed using a phenolphthalein indicato

The shear resistance of reinforced concrete elements without transverse reinforcement relies on the interaction of several resisting mechanisms. In the region close to the supports of a suspended element, the greatest contribution is often provided b

The carbonation exposure classes adopted by EN 206 enforce minimum cement contents for concrete mix design, therefore placing limits on achievable embodied carbon. Understanding the mechanisms behind carbonation of concrete structures would allow for

A shear crack in an RC beam undergoes a load sharing stage where aggregate interlock is dominant along particular segments of the crack path. However, one of the challenges is that this estimation of the aggregate interlock contribution is highly dep

Reinforced concrete half-joint structures, also called dapped-end beams, are a common type of support configuration in bridges and precast structures. They are characterised by a sudden reduction in depth at the end of a suspended structural element.
