Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

Structural Concrete, EarlyView.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Analysis of hydration processes in concrete mixtures modified by the introduction of a nanomodifier by electromagnetic activation [PDF]

Нанотехнологии в строительстве
Introduction. Traditional Portland cement-based concretes are characterized by low flexural tensile strength and a tendency to crack formation. One of the promising ways to solve this problem is the use of carbon nanotubes, which act as crystallization

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams

Structural Concrete, EarlyView.
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

Performance and Compatibility of Phosphonate-Based Superplasticizers for Concrete

Buildings, 2017
The paper deals with the effectiveness of an innovative phosphonate-based superplasticizer (PNH) for ready mixed concrete. Concrete specimens were manufactured by considering a constant initial workability, equal to 220 mm slump at the end of the mixing ...

Shear capacity of reinforced concrete one‐way slabs with intermediate support and distributed loading

Structural Concrete, EarlyView.
Abstract Experimental campaigns on reinforced concrete members, being the basis for database evaluations used for validation of many shear design approaches, mostly include simply supported single‐span beams with concentrated loads. Other support and loading conditions representative for actual slab systems are highly underrepresented.

Structural testing and analytical model of Reinforced Concrete (RC) prisms with 3D‐printed concrete permanent formwork under compressive loading

Structural Concrete, EarlyView.
Abstract The implementation of traditional steel reinforcement in 3D concrete printed structures is a major challenge. Although 3D‐printed structures may be used as formwork, the knowledge about their structural contribution is limited. This research aims to experimentally evaluate the structural performance of reinforced concrete prisms with 3D ...
