“…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.

“…Fly ash, which is produced as a byproduct of coal burning, is commonly utilised as a supplementary cementitious material. There are two primary categories of ash, known as Class F and Class C [28,29,30]. Both varieties can enhance several characteristics of concrete, including sulphate resistance, freeze-thaw resistance, abrasion resistance, and alkali-silica reaction [31,32,33].…”

This research paper explained in detail how well regular concrete works and how well concrete with fly ash and ground granulated blast furnace slag (GGBS) performs as a substitute for cement. Through a series of experiments, the objective of the study was to perform an experiment that promotes the usage of partial replacement-based concrete which can replace the conventional concrete as well as contributes to sustainable development. A dedicated methodology was developed for the study, focusing on the mechanical and durability properties of the materials with inducing sustainable materials. The methodology study examined the mechanical properties, durability, and microstructural attributes of concrete blends. Cement concrete specimens with binder ratios (%) of 0.3, 0.4, and 0.5 were tested for compressive strength, rapid chloride permeability, SEM, and XRD at 28, 56, and 90 days. Fly ash and GGBS were used to partially replace cement at 0% to 70% for all binder ratios by weight of cement. There were optimal replacement percentages for each binder ratio and fly ash; the concrete partially substituted with GGBS had similar or enhanced mechanical properties to conventional concrete. The novelty of the study is to incorporate microstructure analysis for the same samples that shall enable analysing the behaviour of the partial replaced materials with conventional concrete. In connection with the results, the study had found lower RCPT values in partial replacement concrete specimens, fly ash and GGBS increased chloride ion resistance. SEM and XRD analyses revealed the microstructural properties and phase composition of concrete mixtures, showing how supplementary cementitious materials refine pore structure and provide durable hydration products. This study shows that fly ash and GGBS can improve concrete performance as well as reduce impact on environment and applications in construction.

“…Effective resource utilization, sustainable methodologies, and a prosperous economy depend on the responsible and eco-conscious handling of waste materials. Various research studies have delved into possible approaches for waste management on a worldwide scale, including repurposing organic waste for agricultural applications, fortifying landfill stability for construction objectives, and executing methodologies and innovations to transform waste into a reusable resource [1][2][3][4][5][6][7][8]. Currently, the global effort to enhance living conditions requires diligent consideration of environmental challenges across all industries, including construction [1].…”

It is crucial to utilize industrial waste and recycled bricks in concrete production, particularly in lightweight concrete, for the sake of sustainability. The objective of this investigation is to produce sustainable, durable, and structural lightweight concrete by replacing natural aggregates (dolomite and sand) with industrial waste (plastic waste) and recycled bricks (crushed lightweight bricks). Two groups of mixtures were conducted in which coarse plastic waste and coarse crushed lightweight bricks were used to partially and fully replace the coarse aggregate in the first group. In the second group, besides replacing the fine aggregate with fine crushed lightweight bricks, the coarse aggregate is also partially and completely replaced, respectively. This experimental work investigated how sustainable lightweight concrete performs in terms of dry density, compressive strength, resistance to chloride penetration, sorptivity, water permeability, and ecological impact. Based on experimental data, replacing aggregate reduced the density of lightweight concrete by up to 1400 kg/m3, lowered its compressive strength by up to 33.8 MPa upon complete replacement of the aggregate, and diminished carbon emissions by up to 2.05%. Compressive strength correlates directly with dry density and inversely with sorptivity and permeability. Investigations have concluded the potential for producing eco-friendly lightweight aggregate concrete suitable for sustainable structural applications.
