Although a majority of the efforts in the development of composite reinforcements for concrete have focused on rod, tendon and cable type elements, the Shimizu Corp. has concentrated its efforts on the development of grid type forms. These grid type elements consist of high performance reinforcing fibers such as glass, carbon and aramid encapsulated in a resin system, normally a thermoset. The grid type elements can generically be classified into two types namely, NESTEM, which are thin, flat elements used primarily as geogrids, and New Fiber Composite Materials for Reinforcing Concrete (NEFMAC), which are thicker reinforcing elements for use in concrete
