Optimal fluorite/gypsum mineralizer ratio in Portland cement clinkering

Materiales de Construccion, 2016
This paper presents an analysis of the joint effect of fluorite and gypsum as mineralizers in the manufacture of Portland cement. A laboratory- scale Box-Behnken statistical design was used to quantify the effects of the explanatory variables fluorite ...

On the Porosimetry of Clinker

Journal of the Ceramic Association, Japan, 1951
The degree of burning of cement clinker is distinguished by its appearance, generally in most cement factories. Litre-weight (g/l) method is popular one to distinguish the degree of burning quantitatively, but it is very difficult, because its measurement differs by degree of charge into a measure for clinker and personal error is quite great ...

Government Subsidies for Industrial Symbiosis: Is It Always Worth It? Assessing Effectiveness and Efficiency Through Agent‐Based Modeling

Business Strategy and the Environment, EarlyView.
ABSTRACT Policy intervention can be a driver for industrial symbiosis (IS). However, given the wide variety of policy instruments available, policymakers should be guided in the policy design process to ensure that their intervention is effective and efficient. In this paper, we propose an agent‐based (AB) model intended to assess the effectiveness and

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

ExMODE: A comprehensive resource for extremophile genomic and functional exploration

iMetaOmics, EarlyView.
ExMODE (https://db.genomics.cn/exmode/) integrates 3518 samples to build a unified extremophile resource, which hosts 1.35 billion habitat‐specific non‐redundant genes, 5.25 million representative protein structures, 67,026 metagenome‐assembled genomes (MAGs), and 164,132 biosynthetic gene clusters (BGCs). By combining sequence‐, structure‐, and genome‐

Opportunities for Australia Amid China's Carbon‐Neutral Transition: Input–Output Approach With Analysis of Australian Renewable Potential

Sustainable Development, EarlyView.
ABSTRACT A major transformation in China's energy mix is underway as the country pursues carbon neutrality by 2060, posing significant structural challenges for Australia as a major exporter of carbon‐intensive resources. This study examines the economic impacts of China's decarbonisation on Australia by applying static and dynamic input–output (IO ...

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.
