Researchers use reclaimed tire fibers to improve fire resistance of concrete

A new way of protecting concrete from fire damage using materials recycled from old tires has been successfully tested by researchers at the University of Sheffield.

Researchers investigate cement solidification in a microgravity environment

The need to build durable infrastructure on other planets is coming. To prepare, Penn State researchers have been working with NASA to explore how cement solidifies in microgravity environments.

NPCA offers jointed precast pavement tech manual

The National Precast Concrete Association (NPCA) posted its Manual for Jointed Precast Concrete Pavement (3rd ed.). This comprehensive technical manual describes jointed precast concrete pavement systems in detail and presents a step-by-step guide.

Researchers develop method to non-destructively measure concrete salt content

Researchers from the RIKEN Center for Advanced Photonics (RAP) have used a method, using the RANS compact neutron source, to non-destructively measure the salt content of structures such as bridges, tunnels, and elevated roadways, which can suffer from degradation due to exposure to salt from seawater and other sources.

Missouri S&T researcher to test low-cost method of strengthening concrete with nanoparticles

A Missouri University of Science and Technology researcher is working on a safer, simpler and potentially more affordable method of combining nanoparticles with concrete. Dr. Hongyan Ma, Missouri S&T assistant professor of civil, architectural and environmental engineering, compares the technique to blowing bubbles into limewater.

CS Hub at MIT announces concrete freeze-thaw webinar

The CSHub at MIT is hosting a webinar to discuss the role of air entrainment in improving freeze-thaw performance of concrete.  The one-hour webinar will be held on Thursday, July 19, at 11 a.m. Eastern.

ACI increases investment in ACI Foundation research initiatives

The American Concrete Institute (ACI) provided the ACI Foundation with an additional one-time contribution of $360,000.

CB Structures: Tunnel form construction accelerates building, reduces costs

CB Structures, a division of Current Builders, is presently using tunnel form on 40-percent of its projects and predicts an increase due to the state's decreasing labor pool and the critical need for more rental properties in South Florida.
