Abstract null null The application of waste wood-based bio-oil in asphalt binder has illustrated many performance advantages for the pavement. However, the introduction of bio-oil to asphalt binder has challenges associated with poor high-temperature performance. To address this matter, the liquefied 4,4′-diphenylmethane diisocyanate (MDI) was utilized as an additive to enhance the high-temperature performance of wood-based bio-oil asphalt (WBBA), while not reducing its low-temperature propertie...

Abstract null null The durability of reinforced concrete structures in subway engineering is a continuing concern due to the long-term complications associated with the coexistence of sulfate, chloride and electric field. However, there remain challenges towards better characterizing the changes in the mechanical and durability of the influenced structures. In this study, the micro-Vickers hardness was measured to reflect the changes in the local mechanical properties of the cement pastes before...

Abstract null null Acidification damage in anode mortar is caused by anodic reactions occurring during impressed current cathodic protection (ICCP) and significantly affects the lifetimes of external anodes. Hydroxy-activated Mg/Al double oxide (HDMO) material was introduced to mitigate acidification damage by stabilizing the hydroxide content around the external anode mortar. The modified external anode was evaluated by electrochemical and microstructure techniques. The results indicated that H...

Abstract null null Bio-asphalt mixture is prone to strength damage due to its unfavorable high-temperature performance and anti-aging properties. In order to improve the strength of the bio-asphalt mixture, this paper selected rock asphalt to modify bio-asphalt and studied the strength characteristics of rock asphalt modified bio-asphalt mixture. First, the neat asphalt mixture, rock asphalt modified asphalt mixture, bio-asphalt mixture, and rock asphalt modified bio-asphalt mixture were prepare...

Abstract null null There is an increasing demand for lithium, which is perceived as the key element of the green revolution. This green image remains incomplete without the circular economic uptake of delithiated null null null null β null − null null null spodumene (D null null β null null S). In a recent contribution, the authors proved that D null null β null null S has remarkable pozzolanic properties (Karrech et al., 2019). This paper sheds more light on the early-age and long-term behaviou...

Abstract null null Making effective use of recycled fine clay brick aggregate (RFCBA) is of benefit to reserve natural resources and protect the environment. The RFCBA has a high-water absorption capacity, which means it can be potentially used as internal curing agent for low water-to-binder concrete mix. The current study uses RFCBA to replace natural fine aggregate in self-compacting concrete (SSC) and investigates the influence of RFCBA dosage and its moisture content (saturated surface dry ...

Abstract null null The aim of this study is to determine how the mechanical behavior of natural fibers is affected by the environmental and internal relative humidity, especially on the fiber-matrix interface. For that, curaua, jute and sisal fibers were selected. The experimental program commenced determining the fibers’ mechanical properties under tensile stresses, followed by X-ray diffraction measurement, thermogravimetric analysis, infra-red spectroscopy and dynamic water vapor sorption ana...

Abstract null null The application of engineered cementitious composite (ECC) in liquid containing structures (LCS) may help to improve the cracking performance of these structures. This study investigates the hydration temperature, shrinkage, cracking and self-healing behaviors of 10 m length ECC and normal concrete (NC) panels under real field conditions of volumetric strains. The restrained panels of NC and ECCs, with different compositions of fly ash (ECC/FF) and slag (ECC/SL), were designed...

Abstract null null This comprehensive study delves into the preparation and detailed characterization of rigid polyurethane foams (RPUFs) filled with varying content levels (3, 6, 9, 12 and 15 wt%) of turkey feather fibers (TFFs) fabricated from the waste feathers. TFFs-loaded RPUFs were successfully produced via one-shut free-rise method in a closed mold. The obtained foam samples were evaluated by the examination of their chemical structure (FTIR analysis), thermal degradation behavior (TGA an...

Abstract null null With the reduction of high quality raw materials, white Portland cement (WPC) manufacturers are faced with the problem of lack of resources. In this paper, it is found that adding Na3AlF6 can increase the whiteness of WPC, which is helpful to alleviate the scarcity of resources in WPC manufacture. The effect of Na3AlF6 on the mineral compositions, chroma and hydration of the interstitial phase in clinker was studied by the Rietveld method, scanning electron microscope-energy d...
