The sudden increase in industrialization has reduced the availability of natural building materials and triggered growing awareness sustainable practices within construction industry. study presented here deals with marble powder, which is one by-products obtained from industry, as a cement replacement concrete mixtures. main aims will be to investigate impact powder waste on mechanical properties promote recycling various industrial wastes for environmental sustainability. Material testing was conducted levels substitution ranging 0% 50%, resulting evaluated compressive tensile strength over different curing periods. results show that are most efficiently improved when up 10–15%, attaining its full potential after 28 days. Beyond this level 15%, decrease, suggesting higher may not effective. This paper consolidates findings, provides novel comparative analysis, addresses key challenges regarding use providing room future development supplementary cementitious (SCMs), eventually leading sustainability sector.

Waste management is the first priority for many countries, so focus of this research on using waste materials in concrete as fillers and substituting ingredients such crumb rubber (CR) fine aggregates. The utilization has gained attention recently, but CR substitution results a reduction mechanical durability properties due to weak bonding lower stiffness CR. To overcome issue, addition strength-increasing cement substitutes investigated along with (5%, 10%, 15%) aggregates tested behavior concrete. Constant 10% glass powder (WGP) silica fume (SF) were substituted separate mixes. main goal study investigate suitable proportion from SF WGP enhancing rubberized concrete’s evaluate materials’ uses considering various parameters. compared both used well control workability, compressive strength, tensile density, ultrasonic pulse velocity, dynamic modulus elasticity. elasticity was observed incorporation CR, also an increase these fumes cement. It that enhanced better WGP. 5% strength without by 11%. Similarly, 6%.

One of the unifying factors for all countries is large consumption chicken, and other, eggs in food other types economic activity. After using various their intended purpose, a amount waste accumulates form eggshells. Currently, this problem exists needs non-trivial, original solution. The aim work was to fill scientific gap direction studying microstructure formation improved nano-modified environmentally-friendly concrete based on eggshell powder obtaining composition manufacture an industrial sample such material. An obtained, characteristics which were relative standard by modifying it with powder, optimal dosage determined. most effective replacement part cement 10%. maximum increase strength ranged from 8% 11%. modulus elasticity increased 4% compared control samples without powder. reduction deformations under axial compression tension comparison values 5% study composite’s analysis changes occurring due nano-modification, confirmed improvement

Compressed stabilized earth blocks (CSEBs) offer a cheaper and environmentally sustainable alternative to traditional building materials for construction. In addition addressing waste disposal difficulties, the inclusion of additives may improve characteristics compressed (CEBs). This article attempts outline findings researchers who have utilized various manufacturing processes investigated influence binders fibers on properties CEBs. A systematic search Web Science Scopus electronic databases works soil published between 2012 2022 yielded 445 articles, while reports, case studies, conference papers, non-English articles were omitted. Keywords such as “Soil blocks”, “Earth bricks”, others used identify eligible studies. study has been segmented into five sections, including descriptive examination authors blocks, comparative analysis based their processes, physical, mechanical, durability aspects CSEBs, which analyzed determine impact additives. The PRISMA 2020 standards followed in evaluation each record, resulted identification 61 that pertinent study’s objective. reveals more significant improving compressive strength, cyclic wetting-drying erosion (durability) effective enhancing flexural thermal performance. literature review indicates if minimum permissible limits are met, potential partially replace soil. addition, this suggests establishing standardized norms testing protocols ascertain quality safety CSEBs However, is constrained by limited used, governed keywords, resources timeframe could be research avenues future.

The primary objective of this research is to utilize an industrial waste byproduct such as foundry sand (WFS) alternative for fine aggregate in self-compacting concrete (SCC). This focuses on the use WFS SCC enhance durability and mechanical properties, find SCC, reduce disposal challenges WFS, make lightweight environmentally friendly. Initially, was treated with chemical (H2SO4), segregating, sieving remove foreign matter clay content. For study, considered varying percentages 0, 10, 20, 30, 40, 50. investigation, M60 grade per Indian standards EFNARC guidelines. After that, tests various fresh properties each batch flowability passing ability mixes prepared using WFS. Similarly, compressive, flexural, split tensile strength were performed at 7, 28, 90 days curing periods, respectively. Likewise, found all water absorption, sorptivity, resistance attack, chloride ion penetration; these 28 Based experimental investigation it that can be used up 30% without compromising much its properties. Finally, establishes helps reducing generation prevails a meaningful utilization method. will also establish density lightweight, green, sustainable material.

A sustainable substitute for conventional pavement concrete composite is provided by alkali-activated (AAC), which made from industrial byproducts and has less of an impact on the environment than cement-based materials. The purpose this research to combine waste foundry sand (WFS) with recycled aggregates (RCAs) manufacture slag (AASC) create a circular economy model that maximizes use recovered materials, minimizes disposal issues, uses energy during extraction manufacturing raw resources. desirable grade AASC mix was carefully formulated comply Indian Standards high-quality applications. optimal proportions were determined through series experiments based hardened fresh properties concrete. resulting consisted 20% WFS 50% RCA volume. ideal compressive strength 64 MPa attained after 28 days, exceeded required desired paving combination used showed rise 9.67% in split tensile increase 20.3% flexural between period 7 days. Models simple linear regression (SLR) multiple (MLR) predict strength. SLR analysis revealed had considerable negative impacts strength, coefficients -0.026315 -0.13476, respectively. With R-squared value 0.8044, MLR demonstrated strong predictive ability. study focuses how supports resource efficiency, promotes building practices, reduces reliance natural aggregates. findings contribute significantly our understanding AAC might be widely applied industry promote enhance environmental sustainability.
