"We synthesized polyols with high hydroxyl functionalities (FOHs), between 9.0 and 12.6, and characterized them with differential scanning calorimetry, thermogravimetric analysis, and size exclusion chromatography after ...

The availability of natural soils with hydraulic conductivity below 1 × 10−9m/sfor liner systems is declining, while industrial waste such as circulating fluidized bed combustion (CFBC) fly ash remains underutilized...

Recycling of construction waste is essential for sustainable cement-based materials, yet the variable composition of recycled autoclaved aerated concrete (AAC) powder pose significant challenges when used in grouting app...

Interlocking concrete pavers (ICPs) require substantial cement consumption, resulting in considerable embodied carbon emissions, while the regional availability of conventional supplementary cementitious materials is bec...

This research aims to develop polyurethane foam using recycled PET (Polyethylene Terephthalate) and HDPE (High-Density Polyethylene) plastic bottles as substitutes for polyol. Waste PET bottles were recycled through a gl...

The global shift towards sustainability has driven significant advancements in construction methodologies. Among these innovations, 3D Concrete Printing (3DCP) stands out as a transformative technology that employs gantr...

Abstract This study investigates a Persian gum-waste carpet fiber (PG-WCF) composite as a stabilizer for silty soil intended for landfill liner applications and compares its performance with the soil stabilized using ord...

Abstract Composites are increasingly employed in aerospace, automotive, construction, sports, and defense industries owing to their high strength-to-weight ratio, corrosion resistance, and customizable properties. This s...

Abstract Aiming at the problems of easy settlement and insufficient durability of traditional materials under special backfilling conditions in the northwest loess area, this study prepared controllable low-strength read...

ObjectiveSuperfine cement-based grouting materials generally suffer from limitations including high bleeding rates, unfavourable rheological properties, poor stability, and strength retrogression. These issues can be mit...

Abstract The reservoirs in the western South China Sea oilfield are characterized by low permeability, poor pore connectivity, high laminated content, severe pollution, and prominent interlayer contradictions. For this r...

Waste thin plastic wrap in the form of crackle plastic, aluminium coated plastic, other thin plastics, have not yet been widely utilized. Limited un-organic rubish collector willing to receive it. The price is also relat...
