Recycling of melamine formaldehyde waste as fine aggregate in lightweight concrete [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2018
Lightweight concrete production using melamine formaldehyde (MF) waste as fine aggregate by partially replacing river sand was investigated. Two forms of MF waste, granules and waste powder, were employed to produce the concrete of 1,000 and 1,300 kg ...

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.
