Abstract Ultra-high-performance concrete (UHPC) is a new type of with improved features such as high strength, long service life, ductility, and toughness. UHPC’s energy-intensive cement quartz sand may make it unsustainable despite its engineering expertise. Thus, UHPC that energy efficient environmentally benign should use less components industrial wastes. This review consolidates critically...

The development of numerical simulation for Ultra-high-performance concrete (UHPC) and fiber-reinforced concretes (UHPFRC) is fundamental the design construction related structures. simplified engineering stress-strain relationship input values are necessary in finite element modeling. Four-linear curves modified Kent–Park model were proposed to describe tensile compressive relationship, respec...

As an effective method of strengthening concrete in the marine environment, wet bonding has maintained efficient application mode for many years. At present, research on behavior UHPC is very rare, so order to investigate interfacial performance between basalt fiber-reinforced plastic (BFRP) mesh cloth and ultra-high (UHPC) under conditions, forty-eight BFRP-UHPC specimens were carried out infl...

Although ultra-high-performance concrete (UHPC) presents superior mechanical properties and durability compared to conventional concrete; its spalling resistance elevated temperatures is much lower due the high compactness absence of capillary pores. This paper investigated influence lightweight aggregate (LWA) on strength microstructure UHPC enhance temperatures. specimens prepared with LWA as...

Ultra-high-performance concrete (UHPC) has been regarded as promising alternative to provide reliable connections between difference segments (e.g., columns and pier footing/cap) during accelerated bridge construction (ABC) procedures. This paper proposes an innovative layered-UHPC connection for the pre-fabricated segmental (PFS) piers, whose seismic performance was validated through quasi-sta...

Preparing concrete with unpurified sea sand and seawater is of great significance for the construction in coastal areas short river pure water. However, contain a lot chloride ions which may cause steel corrosion problems. In this paper, are used to prepare ultra-high performance (UHPC), potential differences between bars protective layer thickness 5mm 15mm Cu/CuSO 4 reference electrode under t...

The application of Ultra-High-Performance Concrete (UHPC) materials in rehabilitating bridges and constructing primary bridge components is increasing rapidly across the world because their superior strength durability characteristics when compared to regular concretes. However, there have been few new constructed using UHPC with formworks, ready-mix trucks, construction equipment. This paper p...

Abstract Heat treatment is often required for ultra-high-performance concrete (UHPC) to achieve high strength. To broad its use in construction, the effect of different curing conditions on properties UHPC has been developed many years. The experimental investigation large scale fibre reinforced (UHPFRC) beams limited. In present study, UHPFRC specimens and cured at 20 °C were prepared investig...

As an emerging practice of accelerated bridge construction (ABC), top flanges precast deck bulb tee girders (DBTs) can be longitudinally connected on-site using ultra-high performance concrete (UHPC) field joints. Robust UHPC mixes proprietary, expensive and might need special expertise to work with it. Thus, exploring viability alternative materials for such joints could beneficial. Poly Methy...
