Durability of Recycled Concrete Aggregates Prepared with Mechanochemical and Thermal Treatment
TL;DR: In this paper , a combination of three enhancement processes were developed for the effective removal of the cement paste, which are mechanical, chemical, and 400 °C conditioning thermal treatment, and the results show that the proposed mechanochemical and thermal treatment reinforced the quality of the aggregates when compared to the non-treated samples.

Elementary Differential Geometry
TL;DR: The first fundamental form of surfaces is the curvature of surfaces as discussed by the authors, which is defined by Gauss' Theorema Egregium and the Gauss-Bonnet theorem.

Curvature formulas for implicit curves and surfaces
TL;DR: Curvature formulas for implicit curves and surfaces are derived from the classical curvature formulas in Differential Geometry for parametric curves andsurface formulas, and some extensions to higher dimensions are provided.

Evaluation of image analysis techniques for quantifying aggregate shape characteristics
TL;DR: In this article, the most widely used aggregate shape analysis techniques were evaluated and the analysis results revealed that some of the available analysis methods are influenced by both angularity and form changes and, consequently, are not suitable to distinguish between these two characteristics.
