Special Issue Information

Dear Colleagues,

The development of construction materials has become increasingly prominent in the building industry. Research into sustainable construction materials has garnered significant interest from both researchers and builders. As a result, extensive research has led to the successful development and application of various sustainable materials in construction projects. However, achieving high efficiency and the full utilization of these low-carbon materials still requires ongoing research and innovation.

This Special Issue, “Low-Carbon Concrete and Cement-Based Materials Towards Sustainable Construction
”, focuses on the latest advancements in sustainable construction materials, including recycled concrete aggregates. It encompasses both experimental and theoretical innovations related to sustainable materials. Topics of interest include but are not limited to the following aspects:

(1) The development of sustainable construction materials;
(2) The fundamental performance characteristics of sustainable construction materials;
(3) The strength and durability of sustainable construction materials;
(4) The multi-application pathways and evaluation of sustainable construction materials;
(5) Technologies and design methods for improving the performance of sustainable building materials;
(6) The low-carbon analysis and assessment of sustainable construction materials;
(7) The economic analysis of applying proposed sustainable construction materials;
(8) Low-carbon and intelligence construction technologies (3D printing, etc.).

The paper presents experimental studies on the influence of a simultaneous, appropriately proportioned combination of microsilica and fly ash additives on the physical and mechanical properties of ultra-high-performance concretes (UHPCs). Concrete mixtures with the addition of microsilica in the amount of 6.7–14.7% and fly ash in the amount of 8.3–26.7% were analyzed, assuming a constant content of cement, water and superplasticizer. Experimental studies were carried out regarding the consistency of the fresh concrete mixtures and on the compressive strength, flexural strength, tensile splitting strength, secant modulus of elasticity, depth of penetration of water under pressure into hardened concrete and water absorption. The analysis of mechanical properties was carried out during a long maturation period from 2 to 90 days. Additionally, the influence of the cost of component materials on the final cost of concrete was taken into account. The test results indicate the effectiveness of the use of microsilica and fly ash additives in ultra-high-performance concretes and possible directions for optimizing their proportions in order to achieve the intended physical and mechanical properties. The best strength properties were obtained for concrete containing 16.7% fly ash and 13.3% microsilica. The highest resistance to water penetration and absorption under pressure was characterized by concretes containing an increased content of microsilica up to 14.7%. Full article

Understanding the enhancing mechanisms of graphene oxide (GO) on the pore structure characteristics in the interfacial transition zone (ITZ) plays a crucial role in cemented waste rock backfill (CWRB) nanoreinforcement. In the present work, an innovative method based on metal intrusion techniques, backscattered electron (BSE) images, and deep learning is proposed to analyze the micro/nanoscale characteristics of microstructures in the GO-enhanced ITZ. The results showed that the addition of GO reduced the interpore connectivity and the porosity at different pore throats by 53.5–53.8%. GO promotes hydration reaction in the ITZ region; reduces pore circularity, solidity, and aspect ratio; enhances the mechanical strength of CWRB; and reduces transport performance to form a dense microstructure in the ITZ. Deep learning-based analyses were then proposed to classify and recognize BSE image features, with a high average recognition accuracy of 95.8%. After that, the deep Taylor decomposition (DTD) algorithm successfully located the enhanced features of graphene oxide modification in the ITZ. The calculation and verification of the typical pore optimization area of the location show that the optimization efficiency reaches 9.6–9.8%. This study not only demonstrated the deepening of the enhancement effect of GO on the pore structure in cement composites and provided new insights for the structural modification application of GO but also revealed the application prospect of GO in the strengthening of CWRB composites and solid waste recycling.
