“…This suggests that the addition of crushed brick waste decreases MDD and increases OWC due to the lower density and higher water absorption capacity of crushed brick waste. Similar findings have been reported by other researchers [11,12,21], who have confirmed that the replacement of NA with RBW leads to an increase in OWC and a decrease in MDD. Additionally, Ajay et al [22] showed that the incorporation of RBW content leads to the increase of porous crushed clay in the mixtures, which has significant water absorption capacity and may contribute to the slight increase in OWC with increased RBW content in the mixtures.…”

Recycling industrial waste to obtain secondary raw materials is a key focus of environmental policy and circular economy strategies. One such industrial waste, recycled brick waste (RBW), is characterized by high pollution and low recycling rates. This paper evaluates the effects of graded replacement of various RBW sizes as a substitute for coarse and fine natural aggregate (NA) on the mechanical properties and durability of cement treated base (CTB). The novelty of this study lies in the durability evaluation of four types of CTB, including natural, recycled, and mixed CTB. RBW and NA materials are characterized and compared, and the mechanical properties and durability of CTB with RBW materials are analyzed and compared to CTB with 100% NA. The results show that the mixes containing waste bricks exhibit comparable mechanical characteristics and could be used in layers of pavement foundations. Additionally, the durability of the mixes containing RBW yields better results compared to blends containing NA.

“…Moreover, the use of crushed clay bricks as substitutes for natural fine or coarse aggregates in durable concrete has been shown to affect dry density and compressive strength [11]. Geotechnical applications of recycled brick aggregates have also shown favorable characteristics in terms of compaction and shear strength [12].…”

“…As can be observed, the reported XRD analysis of recycled glass particles reveal their amorphous nature, characterized by a minor presence of long-range atomic order. This amorphous phase, typical of soda-lime glass materials [47,49,50,59,78], is a key factor in their pozzolanic activity when used as glass powder in concrete [79,80]. The absence of crystalline structure allows for greater reactivity with calcium hydroxide during cement hydration, resulting in the creation of secondary C-S-H gel.…”

This review article analyzes the influence of recycled glass (as sand and powder) beyond the durability, rheology and compressive strength of plain UHPC, even exploring flexural and direct tensile performance in fiber-reinforced UHPC. Interactions with other mineral admixtures like limestone powder, rice husk ash, fly ash, FC3R, metakaolin and slags, among others, are analyzed. Synergy with limestone powder improves rheology, reducing superplasticizer usage. Research highlights waste glass–UHPC mixtures with reduced silica fume and cement content by over 50% and nearly 30%, respectively, with compressive strengths exceeding 150 MPa, cutting costs and carbon footprints. Furthermore, with the proper fiber dosage, waste glass–UHPC reported values for strain and energy absorption capacity, albeit lower than those of traditional UHPC formulations with high cement, silica fume and quartz powder content, surpassing requirements for demanding applications such as seismic reinforcement of structures. Moreover, durability remains comparable to that of traditional UHPC. In addition, the reported life cycle analysis found that the utilization of glass powder in UHPC allows a greater reduction of embedded CO2 than other mineral additions in UHPC without jeopardizing its properties. In general, the review study presented herein underscores recycled glass’s potential in UHPC, offering economic and performance advantages in sustainable construction.

“…Current ecofriendly concrete structures have been developed to withstand various environmental conditions. Thus, many researchers have used natural resources and waste materials to enhance the properties of sustainable concrete [1][2][3]. Self-curing concrete (SC) is prepared to decrease the need for additional water for concrete curing after it has been placed.…”

This study investigates the properties of sustainable self-curing concrete (SSC) by adding volcanic powder (VP), crushed ceramic (CC), and polyethylene glycol 6000 (PEG). VP and CC are prepared from volcanic ash, as a natural pozzolanic material, and construction waste, respectively. PEG is used as an inner-curing agent. Twenty-six concrete mixtures are prepared using VP at 5%, 10%, 15%, and 20%, CC at 50%, and PEG at 1%, 1.5%, and 2% and tested after 7, 28, and 56 days. Mechanical, workability, and durability characteristics are evaluated using different tests. The bond and cohesion between aggregates and mortar are tested using a scanning electron microscope (SEM). The results show that the optimum replacement mix for enhancing strengths, by producing C-S-H, of the studied SSC is 10% VP and 1.5% PEG. This improved the compressive, tensile, and flexural strengths of SSC by 54.5%, 60.7%, and 34.9%, respectively, compared to a reference mix. Adding CC enhances the compressive strength of SSC by 41.6% and 11.5% and decreases chloride penetration by 10% and 9.1% compared to control mixes. PEG improves the mechanical, workability, and durability characteristics of SSC even with the addition of 1%. The obtained results reveal the possibility of using VP and CC in producing SSC.
