Dynamic Reaction and Damage Evaluation of Reactive Powder Concrete Strengthened Reinforced Concrete Columns Subjected to Explosive Load

Buildings
China has an existing building area of 80 billion square meters, where reinforced concrete structures have a large quantity and a wide surface area. The risk of structures being subjected to blast loading is relatively high.

Molecular Screening of Black Flies (Diptera: Simuliidae) for Vector‐Borne Zoonotic Pathogens, South Moravia, Czech Republic

Zoonoses and Public Health, Volume 73, Issue 1, Page 95-106, February 2026.
ABSTRACT Introduction Black flies (Simuliidae) are globally distributed blood‐feeding arthropods and vectors of viral, bacterial, and parasitic pathogens to many animal species, including humans. We investigated the occurrence of selected vector‐borne pathogens in black flies in South Moravia, Czech Republic, and evaluated their possible role in the ...

Study on Seismic Behavior of Cross-Shaped-Steel-Reinforced RPC Columns

Buildings
Based on the hysteretic tests of steel-reinforced reactive powder concrete (RPC) columns and reinforced RPC columns, the finite element numerical models of these two kinds of RPC columns were established by OpenSees (2016).

Study on Damage Constitutive Model of Reactive Powder Concrete in Uniaxial Tension

Buildings
In this paper, the damage constitutive model of reactive powder concrete (RPC) in uniaxial tension is investigated. The relationship between the uniaxial tensile strength of RPC and the steel fiber admixture was analyzed by preparing RPC specimens with ...

Modeling the Fire Response of Reactive Powder Concrete Columns with Due Consideration of Transient Thermal Strain

Buildings
Transient thermal strain (TS) is a unique compressive strain that reactive powder concrete (RPC) experiences during temperature rise. RPC has a more rapid TS development than normal concrete (NC) during temperatures of 300 °C~800 °C, and under the same ...

Study on freeze-thaw resistance and pore structure deterioration of fly ash reactive powder concrete based on low-field NMR relaxation

Case Studies in Construction Materials
To investigate the effect of fly ash (FA) replacements of cement on the freeze-thaw resistance and microscopic pore structure of reactive powder concrete (RPC), a rapid freeze-thaw test on RPC with different fly ash replacement content was conducted. The
