Cambridge researchers developing self-healing concrete

Researchers at the University of Cambridge are using microencapsulation technologies developed by Dolomite Microfluidics to develop self-healing construction materials. As highlighted in recent BBC News broadcasts, the Department of Engineering’s Geotechnical and Environmental Research Group is developing microcapsules containing ‘healing’ agents – such as minerals, epoxy or polyurethane – which can be added to building materials to allow self-repair of small cracks which develop over time.

Guide to Green Building – Product of the Week

The JEB 3Seal HM+ spacer offers significant aesthetic and energy-efficient advantages. The high-modulus silicone secondary seal minimizes PIB migration, providing clear, straight sightlines. It also offers 35 percent higher design strength, allowing for a narrower air cavity in an IGU, and 10.4 percent more argon gas retention than standard sealants, based on ASTM 2190 testing. An IGU incorporating the JEB 3Seal HM+ spacer will retain its argon gas longer over other insulating glass systems, maximizing energy savings and extending the units service life.
