pozzolanic

adj

1. Having the characteristics of pozzolana, a type of volcanic ash used for mortar or for cement which sets under water.

   “Since this time other workers have confirmed that ground glass exhibits good pozzolanic provided it is ground to sufficient fineness. Little pozzolanic reaction is evident for glass above 300 microns but the pozzolanic activity increases as the particle size is reduced below this size with good pozzolanic properties generally being achieved below about 45 microns (Federico & Chidiac 2009).”
