STRUCTURE FORMATION PROCESS OF HYDRATED PORTLAND CEMENT COMPOSITIONS: NANOSCALE LEVEL CONTROL [PDF]

open access: yes, 2017
Durability of cement-like construction materials, as well as durability of cement stone, depends on their humidity resistance, frost resistance, corrosion resistance. All of these properties depend not only on the composition of the original clinker, but

Development of physics-based compositional parameters for predicting the reactivity of amorphous aluminosilicates in alkaline environments [PDF]

open access: yesarXiv, 2023
The reactivity of amorphous aluminosilicates in alkaline environments is important to many applications, including blended Portland cements and alkali-activated materials (AAMs). Here, two physics-based compositional parameters are derived to describe the relative reactivity of CaO-Al2O3-SiO2 and CaO-MgO-Al2O3-SiO2 glasses in alkaline environments: (i)

A flat posterior cruciate ligament reconstruction restores native knee kinematics, comparable to a double‐bundle reconstruction—A biomechanical robotic investigation

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To biomechanically evaluate a flat posterior cruciate ligament (PCL) reconstruction utilizing rectangular femoral bone tunnels. Methods Eight fresh‐frozen human knee specimens were tested in a six‐degrees‐of‐freedom robotic test setup. In each testing step, a force‐controlled test protocol was performed, including 89 N posterior tibial

Where Should the Old Clothes Go? — Promoting Circularity in Sub‐Saharan Construction Through Textile Waste

open access: yesSustainable Development, EarlyView.
ABSTRACT Textile waste poses a major challenge in the 21st century, particularly for Sub‐Saharan African countries, where local production and high imports lead to excessive waste, often ending up in landfills or incineration. However, opportunities for recycling and repurposing textile waste into construction materials are emerging.
