A synopsis manual about recycling steel slag as a cementitious material

Journal of Materials Research and Technology, 2019
Steel slag (SS) is an industrial product of steel making. It can be produced in either an electric arc furnace (EAF), of which steel is produced by melting scrap steel, or a basic oxygen furnace (BOF), of which iron is converted to steel.

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Effect of the curing conditions of concrete on the behaviour under freeze-thaw cycles [PDF]

, 2011
The aim of this work is to relate the curing conditions of concrete and the addition of an air-entraining admixture with the damage caused by freeze–thaw cycles. In countries with a continental climate, the curing of concrete in summer is performed under

Effect of Different Types of Super Plasticizers on the Properties of High Strength Concrete Incorporating Large Amounts of Silica Fume [PDF]

Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2005
High strength concretes incorporating large amounts of silica fume (SF) are analyzed for different types of admixtures. Properties of fresh and hardened concrete were analyzed for dosages of SF between 30% and 50% and were compared with 10% SF. Influence
