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...

Abstract This study investigates the compressive behavior and analytical modeling of natural and rubberized concretes confined with cost-effective glass fiber-reinforced polymer (GFRP) jackets. Forty-two cylindrical spec...

Abstract To ensure the prefabrication quality of concrete segmental beams for assembled railway bridges, this study investigates the main factors affecting the casting and curing of such beams. Using the Zheng-Xu regiona...

A crucial objective for mitigating the global environmental footprint of the construction sector is the imperative to develop sustainable and ecological concrete alternatives. This investigation presents a novel strategy...

This work describes the effect of biochar (BC) and lightweight expanded clay aggregate (LECA) on the engineering properties (compressive strength, density, porosity, water permeability and sound absorption), CO2 emission...

Abstract Utilization of industrial waste to produce geopolymer concrete is a good answer to minimize the carbon-dioxide( Co2) released from the traditional procedure of producing Ordinary Portland cement (OPC). This not ...

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...

Early carbonation curing is an effective approach to mitigate the environmental impacts of concrete. This is particularly valid when coupled with other strategies, such as substituting cement with alternative low-carbon ...

Abstract Concrete production’s environmental impact has driven the use of supplementary cementitious materials like sawdust ash (SDA) and admixtures such as Conplast to enhance sustainability and performance. This stud...

Reinforced concrete (RC) piers have been widely studied and applied in bridge construction practice. To ensure the normal operation of RC piers under corrosive environments and seismic effects, new corrosion-resistant ma...

Portland cement production is a major contributor to global CO2 emissions, and the scarcity of natural river sand limits conventional concrete production. Despite increasing interest in geopolymer concrete (GPC), studies...

Abstract CO2 curing can greatly enhance the properties of concrete while actively sequestering CO2. However, the influencing mechanisms of CO2 curing on the passivation film of steel bars in concrete remains unclear. In ...

This Effect of Nano-carbon additives on mechanical performance and durability of cementitious composites in oi terms of static and dynamic modulus is studied. A Nano carbon powder was admixed in 5%, 10% and 15 % levels a...

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...

Numerous seismic damage investigations have demonstrated that reinforced concrete (RC) frame structures tend to exhibit a Strong-beam Weak-column failure mechanism, which contradicts the intended Strong-column Weak-beam ...

Online child sexual exploitation and abuse (OCSEA) has developed as an important manifestation of transnational organized crime, constituting a systematic violation of children's fundamental rights under international la...

The choice of building façade materiality and composition plays a significant role in indoor and outdoor thermal comfort as well as energy efficiency. However, the carbon footprint of most construction materials contrib...

Abstract Alkali-activated materials (AAMs) are promising for rapid concrete repair but are hindered by excessive drying shrinkage. This study evaluates the efficacy of MgO-based (MEA), CaO-based (CSEA), and calcium sulfo...

The deposition of fat, oil, and grease (FOG) from food service and residential sources in sewer pipes causes frequent blockages, sanitary sewer overflows (SSOs), and high maintenance costs, mainly due to saponification r...
