“…The CPRAM is characterized by high porosity and low strength compared with conventional concrete materials. To improve its mechanical properties, a total of nine cementitious material proportions were designed based on the orthogonal design method [38,39]. In this research, RA, fly ash, blast furnace slag, and silica fume were considered for the design Sustainability 2023, 15, 14063 5 of 17 of CPRAM mixtures, and three different utilization ratios for these materials to optimize the design of CPRAM mixtures.…”

This paper designed cement-stabilized permeable road subgrade materials. Construction demolition waste with recycled aggregate replaced natural aggregate in cement-stabilized materials to utilize recycled resources for construction solid waste. This paper tests the compressive strength, water permeability, bending strength, and compressive resilience modulus of cement-stabilized permeable recycled aggregate materials under different cementitious additive ratios. The results show that at a recycled aggregate proportion of 30% in cement-stabilized permeable recycled aggregate material, the 7-d unconfined compressive strength exceeds 3.5 MPa, and the permeability coefficient surpasses 3.5 mm/s, which can meet the roadbed requirements in China. The incorporation of recycled aggregates significantly reduces the mechanical properties and water permeability of cement-stabilized permeable recycled aggregate materials, while cementitious additives improve the mechanical properties. Specifically, red brick, old concrete, and ceramics in recycled aggregates weaken the mechanical properties of the skeleton structure of cement-stabilized permeable recycled aggregate materials, and the compressive strength, bending strength, and compressive resilience modulus decrease with the recycled aggregate content. Cementitious additives can fill the micro-pores of the interface transition zone of cement-stabilized permeable recycled aggregate materials to improve the cementation strength between aggregates.

“…Xue et al [11] utilized MSWI fly ash as a partial substitution for fine aggregate or mineral filler in a stone matrix asphalt (SMA) mixture, which saves natural rock completely and promotes a solid waste utilization rate of over 90%. Yao and colleagues [12] evaluated the impact of replacing cement and sand (0-25%) with fly ash (FA) on the mechanical and shrinkage parameters of rapid hardening Portland cement (RHPC) by using the orthogonal design technique and shrinkage Materials 2022, 15, 4142 2 of 13 testing, and increased FA was reported to improve dry shrinkage and plastic shrinkage behavior. There are numerous similar kinds of literature that may be categorized and statistically evaluated in order to properly detect various solid wastes at different times [13,14].…”

The precise and visual analysis of solid waste recycling in concrete construction engineering is critical for the development of ecological civilization and for the secure supply of resources. This research makes a bibliometric analysis of the solid waste application in concrete construction engineering from 2000 to 2021 based on the Web of Science. The global bibliometric status, current research focus and future directions were used to indicate the global development of solid waste recycling in concrete construction engineering. The most reused solid wastes and most solid waste productive regions were concluded with this bibliometric analysis. China is far ahead of other countries in solid waste recycling in all aspects and heavy metal is one of the most prominent solid waste themes in China. By analyzing the most studied solid waste, fly ash appears to be the most popular and is widely used; half of the top ten-cited papers are correlated with it.
