2+ mon, 2+ week ago   (686+ words) Embedded steel tubes have been investigated to assess their ability to strengthen reinforced concrete (RC) beams with longitudinal voids designed to accommodate building services. The embedded tubes were seen to improve load-carrying capacity, stiffness, ductility, and energy absorption, helping to…...

2+ mon, 3+ week ago   (755+ words) Building permanent infrastructure on the Moon and Mars will require construction materials that are available on-site, as transporting cement from Earth is prohibitively expensive and impractical for large-scale construction. As a result, researchers are exploring ways to use planetary regolith…...

2+ mon, 4+ week ago   (463+ words) Concrete remains the most widely used construction material worldwide due to its versatility in infrastructure, including buildings, bridges, and roads. However, traditional Portland cement concrete is associated with high carbon emissions and limited thermal resistance, especially under fire exposure. Download…...

3+ mon, 21+ hour ago   (404+ words) Concrete is the world's most widely used construction material, but producing it consumes vast amounts of natural resources and generates significant carbon emissions. The growing demand for freshwater in concrete production has also become a major concern, particularly in water-scarce…...

3+ mon, 4+ week ago   (466+ words) The European construction sector plays a central role in the region’s energy consumption and carbon emissions. Buildings account for a large share of lifecycle greenhouse gas emissions, making decarbonization a key priority for policymakers. Recent initiatives such as the European…...

5+ mon, 1+ day ago   (468+ words) Researchers used metakaolin, high-calcium fly ash, and waste marble powder to enhance concrete performance. They found that a 12.5% replacement of metakaolin significantly increased the material’s elastic modulus and internal density, offering a practical way to utilize industrial by-products to develop…...

5+ mon, 2+ day ago   (423+ words) Global infrastructure development produces approximately 8% of total human-generated carbon dioxide (CO2) emissions, primarily due to the production of Ordinary Portland Cement (OPC). To address this environmental challenge, a recent study published in the journal Scientific Reports introduced a sustainable inorganic polymer…...

5+ mon, 3+ day ago   (821+ words) A paper recently published in Scientific Reports proposed a hybrid machine learning (ML) model to optimize and forecast the compressive strength of concrete modified with electric arc furnace (EAF) slag. EAF oxidizing slag, ladle furnace slag (LFS), and blast furnace slag…...

5+ mon, 1+ week ago   (525+ words) The global construction sector faces a critical challenge due to the high carbon footprint of Portland cement. In a recent study published in Scientific Reports, researchers introduced a two-stage artificial intelligence (AI) framework for the design of geopolymer concrete (GPC)....
