Materials, Год журнала: 2022, Номер 15(18), С. 6222 - 6222

Опубликована: Сен. 7, 2022

The safe disposal of an enormous amount waste glass (WG) in several countries has become a severe environmental issue. In contrast, concrete production consumes large natural resources and contributes to greenhouse gas emissions. It is widely known that many kinds may be utilized rather than raw materials the field construction materials. However, for wide use building construction, it necessary ensure characteristics resulting are appropriate. Recycled one most attractive can used create sustainable compounds. Therefore, researchers focus on cement mortar by utilizing as aggregate or pozzolanic material. this article, literature discussing recycled partial complete replacement aggregates been reviewed focusing effect fresh mechanical properties concrete.

Geopolymer (GP) concrete is a novel construction material that can be used in place of traditional Portland cement (PC) to reduce greenhouse gas emissions and effectively manage industrial waste. Fly ash (FA) has long been utilized as key constituent GPs, GP technology provides an environmentally benign alternative FA utilization. As result, thorough examination manufactured using precursor (FA-GP concrete) employed replacement for conventional become crucial. According the findings current investigations, FA-GP equal or superior mechanical physical characteristics compared PC concrete. This article reviews clean production, mix design, compressive strength (CS), microstructure (Ms) analyses collect publish most recent information data on In addition, this paper shall attempt develop comprehensive database based previous research study expounds impact substantial aspects such physio-chemical precursors, mixes, curing, additives, chemical activation CS The purpose work give viewers greater knowledge consequences uses making effective

Investigation of the physical-mechanical properties and durability of high-strength concrete with recycled PET as a partial replacement for fine aggregates

Frontiers in Materials, Год журнала: 2023, Номер 10

Опубликована: Янв. 13, 2023

In this study, PET plastic waste, which is a type of polymer commonly used in the manufacture bottles, has been incorporated into concrete by partially replacing natural fine aggregate. An experimental study was conducted casting and testing 90 cylinders 54 cubes. A mixture designed aggregate substituted with waste (PW) at ratio 0%, 25%, 50%, various w/c ratios .40, .45, .55. Physical, mechanical, durability properties were assessed. The downside test results show degradation each following characteristics: slump, compressive strength, splitting tensile ultrasonic pulse velocity, water absorption, porosity. these characteristics increased increase volume (PA) ratio. While positive side showed that PA ratio, fresh dry densities decreased further, using 50% PET, density became below 2000 kg/m 3 . Therefore, it classified as lightweight concrete. Moreover, fracture changed from brittle to more ductile compared control Also, thermal conductivity significantly (11%–47%), less than .71 W/mK, accordingly, bearing insulator.

Abstract A cement‐based material that meets the general goals of mechanical properties, workability, and durability as well ever‐increasing demands environmental sustainability is produced by varying type quantity individual constituents in high‐performance concrete (HPC) ultrahigh‐performance (UHPC). Expensive time‐consuming laboratory experiments can be used to estimate properties mixtures elements. As an alternative, these attributes approximated means predictive models created through application artificial intelligence (AI) methodologies. AI approaches are among most effective ways solve engineering problems due their capacity for pattern recognition knowledge processing. Machine learning (ML) deep (DL) a subfield gaining popularity across many scientific domains result its benefits over statistical experimental models. These include, but not limited to, better accuracy, faster performance, greater responsiveness complex environments, lower economic costs. In order assess critical features literature, comprehensive review ML DL applications HPC UHPC was conducted this study. This paper offers thorough explanation fundamental terms ideas algorithms frequently predict UHPC. Engineers researchers working with construction materials will find useful helping them choose accurate appropriate methods needs.
