Enhancing the Sustainability of Concrete by Adding Recycled Sand and Silica Fume Along with Human Hair Fibers

Journal of Composites Science, Год журнала: 2025, Номер 9(5), С. 216 - 216

Опубликована: Апрель 29, 2025

This experimental study produced recycled sand–silica fume–hair fiber concrete to enhance sustainability. Recycled sand and silica fume can be used address the environmental issues caused by excessive river mining carbon footprint of industry. In addition, waste hair fibers (0.5–2%) were introduced properties newly developed mixes. The absolute volume method was employed for four sustainable A 100 mm slump set as a structural requirement, which maintained adding 0.5%, 1%, 1.4%, 1.9%, 2.6% admixture weight cement proposed compressive strength, splitting tensile density hardened mixtures estimated. results show that combining optimized 10% with 0.5–2% enhanced threshold met when 1.5% mixed fume, 50% manufactured sand, sand. However, strengths mixes 2.0% found almost same at 5.62 MPa 5.65 MPa, respectively. bulk increased increasing percentages fibers. Furthermore, in fibers, very similar 2.708 g/cm3 2.792 g/cm3, Thus, it concluded from containing optimal is acceptable concrete.

Performance of Nanotechnology in Cementitious Materials: Synthesis and Application

Materials, Год журнала: 2025, Номер 18(10), С. 2171 - 2171

Опубликована: Май 8, 2025

Cementitious materials are indispensable in the construction industry and urban development worldwide because cement pastes, mortars, concrete provide mechanical strength, high durability, excellent stability to various structures that used a lot of civil works. Owing impact relevance these materials, it is frequently seek ways improve their properties characteristics. In recent years, nanomaterials such as nanoparticles (NPs) nanofibers (NFs) has allowed cementitious mechanical, thermal, chemical, durability properties, among others. This can be associated with fact allow for improved hydration by retaining water mix, helping define more uniform microstructure and, therefore, significantly reducing porosity, which prevents contamination from entry external agents into structure. addition providing an overview effects using on enhancing this review includes most widely nanomaterial synthesis methods years contribution sustainable environmentally friendly construction.

Rethinking sand as earth material for a sustainable construction in Egypt

Frontiers in Built Environment, Год журнала: 2025, Номер 11

Опубликована: Май 16, 2025

This research investigates the feasibility of using desert sand as a sustainable substitute for traditional construction materials in Egypt. Utilizing local resources Egypt’s extensive landscape could substantially decrease dependence on energy-intensive like Portland cement and clay bricks, thereby reducing environmental impact promoting decarbonization initiatives. takes hierarchical approach to analyzing geological distribution distinct Egyptian kinds, assessing important national initiatives legislation, addition laboratory findings concluded mechanical qualities recent publications. It exposes flaws adopted sustainability programs concrete masonry industries. also techniques, including autoclaved aerated (AAC) blocks, which provide economic advantages compared bricks. Therefore, optimizing use industries is very suitable urban growth, it will enhance initiatives, improve thermal insulation, energy consumption. In accordance this, study highlights necessity additional experimental validation incorporate sand-based into sector, needs be supported by policy interventions standardize generalize materials. concludes with an indicative integration abundant production Pozzolana Cement (PPC) enforcement AAC block usage modular based through standards supply chain optimization.
