Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

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 ...

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

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 ...

High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

Structural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...
