TL;DR: In this article, a servo-hydraulic testing machine was used to study the strain-rate dependent behavior of concrete in tension and the effect of temperature and moisture content on the strain sensitivity of concrete.

TL;DR: In this paper, Monte Carlo simulations of realistic meso-scale models based on high-resolution micro-scale X-ray Computed Tomography (XCT) images, using asymptotic homogenization and the concrete damaged plasticity (CDP) model, were used to characterize mesoscale mechanical behaviors of concrete.

TL;DR: In this article, a quantitative correlation has been established to predict the effects of residual strains on the apparent chloride diffusivity of fatigue-damaged concrete, and the experimental results show that the tensile fatigue damage can accelerate the chloride penetration in concrete by 1.5-3.0 times, when the magnitude of maximum fatigue load is between 25% and 45% of the ultimate tensile load of the specimen.

TL;DR: In this article, the authors developed a facile approach for preparation of porous carbon-confined Ru-doped Cu nanoparticles by direct pyrolysis of the Ru-exchanged Cu-BTC metal-organic framework.

TL;DR: In this paper, the authors investigated the splitting properties of fiber reinforced ground granulated blast furnace slag (GGBFS) concrete after exposure to elevated temperatures, and proposed a set of theoretical equations to predict the residual splitting strength of concrete after being heated to temperatures up to 800 °C.
