The Possibilities for Using Ash and Slag Waste in Civil Engineering

Applied Sciences
This research aimed to improve our understanding of how ash and slag waste (ASW) could be used in civil engineering. The present study concentrated on the utilisation of bottom sand (ASW) in cement composites as a replacement for a part of aggregate and the evaluation of the pozzolanic properties of the material.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Dissolution, Reconfiguration and Formation: Decarbonisation Effects on Regional Industrial Interpath Dynamics

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract Decarbonising mature industries is crucial for achieving overall carbon neutrality. This article provides an interpath dynamics perspective on how mature industries' decarbonisation paths affect interconnected industries via three key interpath transformation dynamics: interpath dissolution, reconfiguration and formation.

Assessing Distinctive Physiochemical Properties of Geopolymers, Their Green Development and Utilization in Wastewater Treatment

Water and Environment Journal, EarlyView.
This review examines the physicochemical properties of geopolymers, focusing on the effects of calcium content, heavy metal impurities and acid activation. It distinguishes geopolymers from other alkali‐activated materials based on structure and synthesis precursors. Their use as water treatment adsorbents is compared with ceramic filters, highlighting

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

Safety Science and Technology, Volume 1, Issue 4, December 2026.
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.

The Use of MSWI Fly Ash in Promoting Low-Titanium Slag Activation for Use in Low-Carbon Cementitious Materials

Recycling
A quaternary solid-waste-based binder was prepared from low-titanium slag, municipal solid waste incineration (MSWI) fly ash, steel slag, and flue-gas desulfurization gypsum (FGDG) to clarify the activating effect of MSWI fly ash on low-titanium slag and
