  • Use of recycled gypsum in road foundation construction

    The project investigate the use of plasterboard gypsum (PG) combined in mixtures with blast furnace slag, cement kiln dust (CKD), cement bypass dust (BPD) and power station run-of-station ash (ROSA) to form a novel blended binder with pozzolanic properties. This novel binder had potential use to stabilise soils and to produce roller-compacted concrete (RCC) for road foundation construction

  • Deep dry mix ground improvement of a soft peaty clay

    The aim of this trial was to evaluate whether a ground granulated blast furnace slag (GGBFS)-red gypsum mixture could be used as a replacement for a cement-based binder. Red gypsum is produced as a co-product to the production of the white pigment titanium dioxide. Trial columns were installed adjacent to the main stabilization works. A combination of in situ and laboratory testing has shown
