Peridynamic modeling for impact failure of wet concrete considering the influence of saturation [PDF]
arXiv, 2022 In this paper, a modified intermediately homogenized peridynamic (IH-PD) model for analyzing impact failure of wet concrete has been presented under the configuration of ordinary state-based peridynamic theory. The meso-structural properties of concrete are linked to the macroscopic mechanical behavior in the IH-PD model, where the heterogeneity of ...

Adsorption of Mercury in Aqueous Solutions by Functionalized Cellulose Extracted from Soybean Hulls
ChemPlusChem, EarlyView.Reuse of agricultural waste as a source of adsorbent cellulose‐based materials is a low‐cost and sustainable approach to remove potentially toxic elements (PTEs) from aqueous solutions. This approach is successfully applied in the removal of mercury from aquaculture water, an important source of food where the absence of PTEs is a fundamental requisite

Effects of elevated ground temperatures on properties of cement grouts for deep rock grouting
Deep Underground Science and Engineering, EarlyView.When the temperature is up to 35°C, significant improvement in rheological parameters, acceleration of grout setting, and an increase in the rheological time dependence of thick cement grout can occur, but there may be a slight effect on the initial grout flowability and the nature of shear thinning.
