Article Abstract
This review provides a comprehensive overview of the advancements in magnesium-based cementitious materials (MBCMs), including magnesium oxychloride cementitious material (MOC), magnesium oxysulfate cementitious material (MOS), and magnesium phosphate cementitious material (MPC). The hydration processes and products, performance characteristics, and applications in soil stabilization are systematically discussed. Key findings reveal that MOC exhibits rapid strength development and excellent thermal stability, while MOS demonstrates improved water resistance and mechanical properties. MPC is highlighted for its effectiveness in the immobilization of heavy metals. The environmental impact of MBCMs is also evaluated, highlighting their potential for sustainable development in civil engineering applications. The primary issues and challenges for MBCMs in soil curing include the insufficient stability of hydration products and inadequate understanding of curing mechanisms, leading to variable material properties and difficulties in precisely controlling the curing effects in practical engineering. Additionally, the complex composition of MBCMs and the highly variable characteristics of natural soils result in significant differences in curing effectiveness under different conditions, restricting their application scope and posing risks to project costs and quality stability.

The greenhouse effect, which affects ecosystems, weather patterns, and global temperatures, has been exacerbated by the increase in air concentrations resulting from the expansion. Direct air capture is a critical component of the strategy to combat climate change and is also essential for carbon capture, utilization, and storage, however, they are currently prohibitively expensive for practical applications, which underscores the necessity of selecting a low-cost material that has exceptional carbon capture efficacy. Considering their straightforward and economical production processes, cementitious materials are recognized as potential candidates.

Large volumes of concrete wastes are produced during building demolition that potentially can be reused as a secondary material. Reuse of crushed cementitious construction wastes as a fill material can result in leaching of reactive cement phases. The short-term dissolution kinetics of crushed concrete waste (CCW) from a UK nuclear site were studied in leaching tests using deionised water, acidic and alkaline leachants.

Foamed concrete (FC) is a lightweight cementitious material made by adding a stable pre-formed foam to a cement paste or mortar to make a homogenized mixture of a controlled low density. The present work aims at evaluating the effect Scrap Aluminum Engine Residue (SAER) has on fresh, mechanical, thermal, and microstructural properties of FC with a water-to-cement ratio of 0.4 at targeted densities of 900 kg/m (FC-900) and 1100 kg/m (FC-1100).

In recent years, the use of supplementary cementitious materials (SCMs) in building materials has increased due to concerns about CO emissions from the cement industry. On the other hand, the scarcity of traditional sources of SCMs in certain regions exacerbates the issue of high demand for these materials in concrete production. In this context, this article explores the chemical, mineralogical, morphological, and physical properties and pozzolanic activity of two types of diatomaceous earth (DE) obtained from industrial waste and by-products.

This study presents the development of a reliable predictive model for evaluating key physical and mechanical properties of cement-based composites modified with granite powder, a waste byproduct from granite rock cutting. The research addresses the need for more sustainable materials in the concrete industry by exploring the potential of granite powder as a supplementary cementitious material (SCM) to partially replace cement and reduce CO emissions. The experimental program included standardized testing of samples containing up to 30% granite powder, focusing on compressive strength at 7, 28, and 90 days, bonding strength at 28 days, and packing density of the fresh mixture.
