Abstract

This work briefly introduces geopolymers and some geopolymer composites having typical molar compositions of SiO 2/Al 2O 3 = 4, M 2O/SiO 2 = 0.3, and H 2O/M 2O =11, where M = Na, K, or Cs. As seen by SEM and TEM, the microstructure was a nanoparticulate (<10 nm) and nanoporous material having a nominal composition of 4SiO 2·Al 2O 3, cross-linked with cations from Na 2O, K 2O, or Cs 2O. Some structural geopolymer composites reinforced with stainless steel powder, basalt chopped fibers, and/or fiber weaves were prepared. Using six layers of natural basalt fiber weave reinforcements, the three-point bending strength and work of fracture of / in. 2 × 6 in. long bend bars were increased from an average of 2.75 to 10.25 MPa and from 0.05 to 21.82 kj/m 2, respectively.
