Fracture properties of geopolymer paste and concrete

Geopolymer concrete is thus believed to be suitable for structural applications. With regard to safety assessment and design of concrete structures, it has been recognised that the fracture properties of concrete need to be considered in structural design (Hilsdorf and Brameshuber, 1991).

This paper presents the development of a mix design method for geopolymer mortar mixes with a principal focus on compressive strength. The method is based on the hypothesis that the overall strength of geopolymer mortar depends on the strength of the geopolymer binder materials, the packing density of the aggregates in the mortar and the amount of geopolymer binder.
