Recycled Concrete Powder Offers Viable Low-Carbon Alternative for 3D Printed Cement Mixes

4 days ago | azobuild.com | Bethan Davies |Nidhi Dhull

Reviewed by Bethan DaviesResearchers have found that recycled concrete powder (RCP) can replace up to 50 % of Portland cement in 3D-printed mixes—reducing carbon emissions by over half while maintaining printability. The study evaluated two types of RCPs in cementitious pastes using rotational rheometry, isothermal calorimetry, and life cycle assessment (LCA), along with printability tests to assess extrudability and buildability.
New Model Shows How Tall Buildings Can Withstand Big Quakes

Reviewed by Lily Ramsey, LLMA recent article in Buildings introduced a numerical model of an 18-story reinforced concrete frame with a core tube and a double-layer seismic isolation system. Designed using YJK (3.0) and simulated in ABAQUS, the model was used to evaluate how high-rise buildings respond to three different seismic waves. BackgroundTo minimize earthquake damage, engineers have developed various structural systems based on seismic isolation principles.
New Plant-Inspired Cement Material Achieves Record Thermoelectric Performance for Energy-Harvesting Buildings

5 days ago | azobuild.com | Bethan Davies |Nidhi Dhull

Reviewed by Bethan DaviesIn a notable advance for smart construction materials, researchers have developed a bio-inspired cement–polyvinyl alcohol (PVA) composite (CPC) that significantly boosts thermoelectric efficiency, opening the door to self-powered buildings and infrastructure. Published in Science Bulletin, the study introduces a composite that mimics the layered stem structure of plants.
Recycled Plastics in Construction

6 days ago | azobuild.com | Bethan Davies |Ankit Singh

Reviewed by Bethan DaviesIt’s no secret that we have a plastic problem. Back in 1950, the world produced just 1.7 million tons of plastic. Fast forward to 2020, and that number exploded to over 367 million tons. And we’re not slowing down. Most of this plastic doesn’t get reused—about 79 % ends up in landfills or polluting natural environments.
Geopolymer Concrete Using Gold Ore Tailings and Recycled Aggregates

1 week ago | azobuild.com | Lexie Corner |Nidhi Dhull

Reviewed by Lexie CornerA recent article in Scientific Reports looks at how gold ore tailings (GOTs) and recycled coarse aggregates (RCAs) can be used as substitutes for river sand (RS) in geopolymer concrete (GPC). The study focused on how durable this type of concrete is, especially when exposed to sulfates and chlorides.

Ground Drones Are Transforming Construction Site Audits: A Fresh Approach to Scan-vs-BIM

1 week ago | azobuild.com | Bethan Davies |Nidhi Dhull

Reviewed by Bethan DaviesA team of researchers has recently explored the use of a ground-based drone to audit construction sites by identifying variations and deviations from planned building information modeling (BIM). The study introduces a new tool designed for time-based Scan-vs-BIM auditing and demonstrates its accuracy and effectiveness in detecting structural discrepancies through experimental validation.
BIM and SHM Unite on a Massive Scale

1 week ago | azobuild.com | Bethan Davies |Nidhi Dhull

Reviewed by Bethan DaviesA recent project in southwest China has demonstrated how building information modeling (BIM) can be effectively integrated with structural health monitoring (SHM) in a large-scale, real-world setting. Using a lightweight BIM model embedded into the web-client of an SHM system—via the skeleton-template method, CATIA platform, and sensor data—researchers explored the practical benefits of this combined approach on a butterfly arch bridge.
AI in Construction Management: A Trend Worth Watching

Nature-Inspired Lightweight Cement Material Cuts Carbon Emissions and Boosts Strength

2 weeks ago | azobuild.com | Bethan Davies |Nidhi Dhull

Reviewed by Bethan DaviesA new study introduces a cement-based material that is lightweight, low-carbon, and exceptionally tough—drawing inspiration from nature’s porous structures. Published in Nature Communications, the study presents LLST (low-carbon, lightweight, strong, and tough), a novel cement-based material that combines reduced environmental impact with impressive mechanical performance.
Geopolymer Concrete with Recycled Fillers Shows Strong Results in Durability Testing

2 weeks ago | azobuild.com | Bethan Davies |Nidhi Dhull

Reviewed by Bethan DaviesA new study published in Scientific Reports shows that recycled concrete powder (RCP), clay brick powder (CBP), and volcanic pumice powder (VPP) can improve the strength and durability of geopolymer concrete (GPC) when used under water curing conditions—pointing to a promising path for more sustainable construction materials. Why It MattersConcrete remains one of the most widely used materials in infrastructure, prized for its strength, low porosity, and long lifespan.
