The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

steel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Instantaneous Capture and Mineralization of Flue Gas Carbon Dioxide: Pilot Scale Study

, 2010
Multiple CO2 capture and storage (CCS) processes are required to address anthropogenic CO2 problems. However, a method which can directly capture and mineralize CO2 at a point source, under actual field conditions, has advantages and could help offset ...

Enhancing durability of steam‐cured precast concrete culverts using SCMs: A comparative study with delithiated beta spodumene

Structural Concrete, EarlyView.
Abstract Steam curing is commonly used to manufacture precast culverts to accelerate early strength development. This study investigates the effect of supplementary cementitious materials (SCMs) on the permeability properties of steam‐cured precast concrete culverts.

Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.
