Geopolymer cement and concrete: Properties - ScienceDirect

01/01/2020  The effect of conventional heating on compressive strength of Fly ash based geopolymer concrete in presence of kaoline at 7 days is given in Fig. 4. The strength increased up to 100 °C and decreased at 120 °C. At higher temperature the loss in compressive strength may be due to excessive loss of moisture loss and crack formation .

10/06/2020  The embodied energy of cement concrete was, with 1.01 GJ/t, about three times higher than for the liquor geopolymer concrete. Considering only the binder, the embodied energy of the BR-derived geopolymer was only one fifth of the OPC binder. Attention was directed to the fact that in case the liquor is considered as a waste product, its embodied energy drops to 0 (since the impurity load

01/03/2020  Furthermore, geopolymer concrete shows much higher thermal resistance compared to OPC concrete [210,211]. When fibers are included, the high-temperature performance of reinforced geopolymer composites is not only related to the individual properties of geopolymer or fiber but also dependent on the thermal compatibility between fiber and matrix.

01/03/2019  The water demand of geopolymer concrete increased with higher silica fume content in the mix formulation. All the geopolymer samples showed a longer initial and final setting time than OPC. This allowed for longer transport times from the batching plant to the construction site. The setting time of the geopolymer mortar can be significantly shortened with the increasing inclusion of silica ...
