A novel carbon-neutral grout, CSRGF, has been developed by recycling waste fluids from geothermal energy harvesting plants, addressing environmental challenges in traditional grouting methods. The new material shows remarkable performance, with a 50% increase in liquefaction resistance and superior water-sealing properties.
Researchers from the University of Houston have confirmed alarming rates of subsidence in Miami's barrier islands, with 35 skyscrapers sinking up to three inches into the ground since 2016. The study used InSAR technology to detect changes in the earth's surface and found that construction-induced stresses extend beyond building footpr...
Researchers developed two models to evaluate personal learning performance, combining biometric responses with demographic data. The simplified forecast model showed higher accuracy and reduced overfitting than the full forecast model.
A new system called ViPER+ uses ultra-wideband technology to track workers' locations on job sites, enhancing safety by detecting violations of location-based policies. The system was tested in two construction zones with students playing the roles of workers and vehicles, demonstrating its accuracy in non-line of sight situations.
The novel portable wireless sensing system measures strain and acceleration in real-time, generating a safety assessment report to prevent damage and ensure safe delivery. While effective, the system lacks real-time data management capabilities, requiring future development of a cloud-based monitoring system.
Researchers developed an intelligent compaction technology that integrates into a road roller, assessing real-time the quality of road base compaction. This improves road construction, reducing potholes and maintenance costs, leading to safer and more resilient roads.
A recent study published in Engineering Construction & Architectural Management identified the main obstacles preventing digital transformation in the engineering and construction industry. The three main problems are a lack of laws and regulations, a lack of support and leadership, and a lack of resources and professionals.
Researchers at Shibaura Institute of Technology develop a fast and reliable method to detect defects in concrete structures using laser-induced plasma shock waves. The technique analyzes vibration patterns to identify Rayleigh waves, which can reveal the presence of cracks.
Researchers at MIT created a computational tool to minimize embodied carbon in truss structures by choosing between timber and steel. The analysis suggests that substituting materials or changing the structure can significantly reduce emissions, with potential savings of up to two times current levels.
A European project developed standard solutions for energy refurbishment, considering various climate zones.
