PALM KERNEL SHELL AS AGGREGATE FOR LIGHT WEIGHT CONCRETE

Nigerian Journal of Technological Development, 2022
In this study, the effect of replacing the conventional gravel with palm kernel shell as aggregates in making concrete volumes of palm kernel shells were used in two (4) different proportions with the other constituents and the strength of the concretes

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Evaluation of the effect of fly ash and zeolite powder and glass fiber on flexural behavior of structural lightweight beams made of Scoria [PDF]

Journal of Structural and Construction Engineering, 2020
Lowering the weight of concrete used in buildings and other structures has been one of the main priorities of the specialists. This will reduce the dead load and the forces involved in the structure during the earthquake.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Performance of Fiber Light-Weight Aggregate Concrete Exposed to Elevated Temperatures [PDF]

Engineering and Technology Journal, 2009
Two major problems arise when concrete is exposed to elevatedtemperatures. One is the deterioration in mechanical properties of concrete and the other problem is spalling of concrete.

Behavior of strengthened Timber Concrete Composite under axial loads

Case Studies in Construction Materials, 2021
The research study focuses on different strengthening techniques for timber concrete composites (TCC) using different types of wire and wire mesh integrated with a layer of epoxy on a timber core embedded in concrete using experimental and analytical ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...
