Abstract India’s cement industry is the second largest in world, generating 6.9% of global output. Polycarbonate waste ash a major problem India and around globe. Approximately 370,000 tons scientific are generated annually from fitness care facilities India. helps reduce environmental burden associated with disposal decreases need for new raw materials. The primary variable this study quantity polycarbonate (5, 10, 15, 20 25% weight cement), partial replacement cement, water-cement ratio aggregates. mechanical properties, such as compressive strength, split tensile strength flexural test results, mixtures were superior at 7, 14 28 days compared to those control mix. water absorption rate less than that standard concrete. Compared conventional concrete, concrete undergo minimal loss under acid curing conditions. utilized construction pollution improve economy. This further simulated characteristics made using least absolute shrinkage selection operator regression decision trees. Cement, waste, slump, absorption, main components considered input variables. suggested tree model was successful unparalleled predictive accuracy across important metrics. Its outstanding ability (R 2 = 0.879403), 0.91197), 0.853683) confirmed method preferred choice these predictions.

This paper reviews recent developments and proposes perspectives for future research on three-dimensional printing concrete (3DPC). review originally analyses the 3DP applications combined with types that are classified into three groups: functional concrete, sustainable special concrete. The technique shows different effects due to various modification methods (e.g., nano-additive, fibre addition, chemical reagent) challenging requirements anisotropy exploit defect). Summarily, oriented of 3DPC is a double-edged sword, asking optimal structural design engineered cementitious composite (ECC), ultra-high-performance (UHPC), most fibre-improved not propitious all types, such as foam because additional pressure in process poses huge disadvantage stability. also protentional from view features, which represents contribution advanced technology development direction.

Researchers have shown significant interest in the incorporation of nanoscale components into concrete, primarily driven by unique properties exhibited these nano elements. A nanoparticle comprises numerous atoms arranged a cluster ranging from 10 to 100 nanometers size. The brittleness foamed concrete (FC) can be effectively mitigated incorporating nanoparticles, thereby improving its overall properties. objective this investigation is analyze effects calcium carbonate nanoparticles (CCNP) FC on mechanical and durability had 750 kg/m3 density, which was achieved using binder-filler ratio 1:1.5 water-to-binder 0.45. CCNP material purity level 99.5% possessed fixed grain size 40nm. total seven mixes been prepared, at specific weight fractions 0% (control), 1%, 2%, 3%, 4%, 5%, 6%. that were assessed include slump, bulk flexural strength, splitting tensile compressive permeable porosity, water absorption, drying shrinkage, softening coefficient, microstructural characterization. results suggest enhances properties, with most optimal improvement observed addition 4%. In comparison control specimen, it specimens containing 4% demonstrated significantly higher capacities compressive, tensile, tests, increases 66%, 52%, 59% respectively. resulted an porosity absorption. However, also led decrease workability mixtures. Furthermore, study provided correlations between strength as well strength. addition, artificial neural network (ANN) approach employed, utilizing k-fold cross-validation, predict confirmation property enhancement verified through utilization Scanning Electron Microscope.

The article provides a comprehensive overview of the research utilizing waste engine oil (WEO) in asphalt binders for multiple application purposes and economic environmental implications. It covers various types sources WEO information on their characteristics process preparing WEO-asphalt binders. study collects effects different applications, including modification, aged rejuvenation, self-healing agents, composites. also discusses work appraisal associated with wide utilization. exhibits both positive negative influences properties. Generally, it improves performance at low temperatures, specifically terms reducing issues like thermal cracking enhancing fatigue resistance. However, may have impact modified high temperatures. WEO, due to its concentration light components, enhances overall asphalt. integration reclaimed can enhance crack resistance, which however highly relies added quantity. Future should be prioritized understand binder compatibility between rejuvenator compound asphalt, effect durability mixes. In addition, field investigation analyse are required bigger, inclusive more detailed picture impacts.
