Players in the cement and concrete sectors are working diligently to achieve a reduction in emissions. However, there are multiple gaps in knowledge about the extent of these emissions, which makes it difficult to determine how effective new initiatives are at reducing emissions. A group of researchers from several universities in the United Kingdom are conducting a large-scale study to help fill this knowledge gap.
Read MoreVarious regional and global groups within the cement and concrete industry are actively working to help achieve a reduction in emissions in this sector. The Cement Association of Canada is one such group, and today’s CTT looks at several prominent initiatives the Association has helped launch this past year.
Read MoreCurrent industry practice for detecting and monitoring alkali-silica reactions in concrete requires destructive extraction and analysis of concrete cores. Argonne National Laboratory researchers explored the potential of using electrochemical impedance spectroscopy for nondestructive evaluation of this reaction instead.
Read MoreSulfate attack is one of the most damaging causes of concrete deterioration. Two studies published this month look at the potential of new geopolymer mortars and the addition of nano alumina to improve concrete’s resistance to sulfate attack.
Read MoreWind instruments can be made from an array of materials because the sound depends mainly on how the air is shaped rather than the instrument’s body. Learn how a German mechanical engineer used 3D printing to design a trumpet out of concrete.
Read MoreThough construction season is mainly ended for the year, sometimes critical construction projects cannot wait until spring. Learn how to effectively pour concrete in cold weather.
Read MoreHighway construction can take longer than is necessary if cars drive on the concrete before it has fully matured. Purdue University researchers are working with the Indiana Department of Transportation to test piezoelectric sensors that measure concrete strength.
Read MoreUnited States’ infrastructure is in dire need of repair. Hydrodemolition is an ideal method for concrete reconstruction. Learn about hydrodemolition history, advantages of the technique, and what to consider before choosing it for your project.
Read MoreWhat causes explosive spalling of concrete? Researchers from Empa, the University of Grenoble, and the Institut Laue-Langevin performed neutron tomography on exploding concrete cubes to find out.
