A Complex Organomineral Admixture For Cement Saving

open access: yesJournal of Architectural and Engineering Research, 2022
The aim of the research is to prepare a composition of a complex organomineral admixture based on industrial waste for cement saving, to experimentally establish the optimum crushing degree of an ash-and-slag waste composition and to estimate the ratio ...

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

open access: yessteel 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

open access: yesSafety 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.

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

open access: yesStructural 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.

Seismic performance of coal ash slag concrete beam-column joints [PDF]

open access: yesJournal of Hebei University of Science and Technology
To investigate the high-value and high-dose utilization of solid waste gasification ash in concrete components, low-cycle reciprocating loading tests were performed on joints within one ordinary concrete and three gasified ash concrete beam-column joints.

BUILDING CERAMICS BASED ON ASH AND SLAG WASTE

open access: yes
The results of research on the influence of ash-slag and wood waste, as well as surfactants on the properties of ceramic masses are presented. It is shown that complex activation of ash-slag ceramic mass by corrective additives in the form of surfactants leads to a decrease in molding humidity and improvement of physical and mechanical properties of ...

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

open access: yesStructural 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.

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures

open access: yesStructural Concrete, EarlyView.
Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.
