Mechanical Performance and Recyclability of Cement-Stabilized Materials with Different Gradation of Recycled Brick-Concrete Aggregates

Utilization of Recycled Brick Aggregate in Cementitious Composites: Mechanical Performance, Cement Matrix Solidification Effect and Life Cycle Assessment

The growing production of construction and demolition waste has been stimulating the need to look for sustainable alternatives to natural aggregate used in the production of cement composites. This study evaluates the potential use of recycled brick material as a substitute for natural coarse aggregate in terms of envi...

Mechanical performance, durability, and hydration characteristics of binary and ternary blended mortars incorporating waste glass powder and Ethiopian scoria

The utilization of supplementary cementitious materials has become a key strategy for improving the sustainability and performance of cement-based materials. This study investigated the mechanical, durability, and hydration characteristics of mortars incorporating scoria powder (SP) and Glass–scoria powder blends (GPSP...

Mechanical and microstructural stabilization of expansive clay using recycled concrete and waste glass for sustainable pavement subgrades

Performance of Recycled Concrete Aggregate and Reclaimed Asphalt Pavement in Concrete: A Systematic Review of Mechanical, Physical, and Durability Characteristics

The increasing generation of construction and demolition waste, along with the depletion of natural aggregates, has driven growing interest in recycled concrete aggregate (RCA) and reclaimed asphalt pavement (RAP) as sustainable alternatives in concrete production. However, a direct and systematic comparison between th...

Mechanical and durability characteristics of SCC incorporating recycled aggregate and steel slag

This study presents a detailed investigation of the properties of self-compacting concrete (SCC) incorporating steel slag-based granulated slag aggregates (GSA) and recycled aggregates (RA) as substitutes for M-sand (MS) and natural coarse aggregates (NCA), respectively. NCA was replaced with coarse recycled aggregate...

Performance Evolution and Microstructure Optimization of Recycled Fine Aggregate Rapid-Hardening Sulfoaluminate Cement Mortar by Nano-SiO2 Surface Modification

In this study, rapid-hardening sulfoaluminate cement (SAC) was used as cementitious material, and recycled fine aggregates (RFAs) were surface pretreated by immersion in nano-SiO2 (NS) suspensions. NS-modified SAC recycled fine aggregate mortars were prepared at three cement–sand ratios (1:1, 1:2 and 1:3) to systematic...
