The low water/binder ratio of ultra-high performance concrete (UHPC) often results in its high autogenous shrinkage. Our study explored the effect of the single or binary addition of a CaO-based expansive agent (CEA) and steel fibers on flowability, compressive strength, flexural strength, microstructure, and autogenous shrinkage of UHPC. X-ray dif...

This study predicted the fatigue life (N) of UHPC incorporated with different volume fractions ( V f = 0.0%, 0.5%, 1.0%, 1.5% and 2.0%) of steel fiber under flexural cyclic loading at various stress levels (S). The Weibull distribution, a two-parameter model, was utilized to estimate the distribution of fatigue life in UHPC. Subsequently, three met...

Concrete is an important construction material globally. Reactive Powder Concrete (RPC), also called Ultra-High-Performance Concrete (UHPC), represents a new type that differs significantly from traditional concrete. This new concrete was developed by Bouygues laboratory in France during the 1990s. It is characterized by its ultra-high strength and...

The study aims to substitute river sand used in ultra-high performance concrete (UHPC) with pond ash (PA), a waste by-product from the Sikka thermal power station in Gujarat, India, at replacement levels ranging from 0 to 20%. Also, 20% of the cement was replaced with ground granulated blast-furnace slag, which is a sustainable, eco-friendly materi...

This study examines the impact of the recycled brick powder (RBP) replacement rate, especially at elevated temperatures on RBP-ultra-high-performance concrete (UHPC) properties such as the stress–strain curve, Poisson’s ratio, elastic modulus, and axial compressive strength through uniaxial compression experiments. The results show that with the in...

The failure of ultra-high performance concrete (UHPC) under axial compression has significant brittleness, so it is necessary to use fiber reinforced polymer (FRP) to constrain UHPC for achieving ductile failure. This article mainly summarized the research progress of FRP constrained UHPC columns, analyzed the influence of different variables on th...

Accelerated bridge construction is crucial in bridge engineering. In order to improve the seismic performance of prefabricated columns, this study proposes using ultra-high performance concrete (UHPC) in the plastic hinge areas of prefabricated columns with bellows grouting connections. In particular, cyclic loading tests are carried out on four 1/...
