A mix design procedure for geopolymer concrete with fly ash

Ferdous et al. (2013) proposed a mix design for fly ash based GPC by considering the concrete density variability, specific gravity of the materials, air content, workability, and the strength requirement. The significant issue that arises in their design process could be the selection of activator solution to fly ash ratio, and also in determining the exact activator solution content with respect to the fly ash content.

PDF Is Geopolymer Concrete a Suitable Alternative to

cement systems containing high volume replacement of fly ash or GGBS and many geopolymer binders do develop compressive strength slowly. However, this particular geopolymer concrete develops its strength quite rapidly with design strength typically achieved after 7 days under laboratory conditions as seen in Figure 1.

Development of mix design method for geopolymer concrete

This study proposes a geopolymer concrete (GPC) mix design method for low calcium (class F) fly ash based incorporating alccofine with the focus on achieving the required compressive strength and workability at heat and ambient curing. Key factors identified and nine mixes with varied fly ash content (350, 375 and 400 kg/m3) and different molarity (8, 12 and 16M) of NaOH solutions were prepared.

Creep and shrinkage behavior of fly ash based geopolymer

The manuscript presented herein is based on the investigation of the short and long term properties of fly ash based geopolymer concrete (GPC) and their link to fly ash characteristics. Fly ash (FA) exhibits a significantly different particle morphology, which impacts the mechanical properties of the resulting GPC and typically contains impurities that fluctuate from one FA source to another.
