Admixtures

, 2013
To commence the discussion of admixtures in alkali-activated binders, it is necessary to first give a brief discussion on the definition of the word ‘admixture’. Many of the components which are essential to the formulation of alkali-activated binders are sometimes described as admixtures (mineral or chemical) in Portland cement systems. In the context

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Novel waterproof ambient cured geopolymer concrete using integral crystalline waterproofing admixture

Advances in Civil and Architectural Engineering
Geopolymer concrete (GC) is a promising alternative to conventional cement concrete owing to its environmental benefits. However, water penetration, which is a common concern, significantly affects the performance of GC, thus causing efflorescence ...

Forensic parameters and admixture in seven geographical regions of the Guerrero state (South, Mexico) based on STRs of the Globalfiler® kit

Annals of Human Biology, 2018
Background: New commercial STR kits have emerged with greater numbers of markers, which allows for obtaining stronger conclusions in forensic casework, which has been poorly studied in Mexico. Aim: To obtain forensic parameters and to analyse the genetic

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

The Peopling and Migration History of the Natives in Peninsular Malaysia and Borneo: A Glimpse on the Studies Over the Past 100 years

Frontiers in Genetics, 2022
Southeast Asia (SEA) has one of the longest records of modern human habitation out-of-Africa. Located at the crossroad of the mainland and islands of SEA, Peninsular Malaysia is an important piece of puzzle to the map of peopling and migration history in

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Analysis of alternative sustainable approach to concrete mixture design

Journal of Sustainable Construction Materials and Technologies, 2022
Sustainability is a growing area of concern, especially amid the concrete industry. Concrete, especially traditional concrete, which contains Portland cement, is extremely harmful to the environment producing mass amounts of carbon dioxide. Additionally,

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...
