The CRC-concept also has military applications because of the high strength and ductility.
A research project with the Swedish military involved testing of heavily reinforced slabs with a thickness of 20 cm. The slabs were placed 5 behind each other. They were then fired upon (from a distance of 300 meters)with a grenade weighing 45 kg and with a length - prior to impact - of 50 cm. Conventional concrete was demolished completely, while the grenade was trapped in the first of the CRC plates.
Other research has included a series of impact tests carried out at University of British Columbia and tests are currently being carried out at Technion in Israel. In these tests a number of reinforced panels will be shot at using a gas-driven cannon.
