TL;DR: In this paper, a fly ash-based geopolymer concrete for curing in ambient condition can be proportioned for desirable workability, setting time, and compressive strength using ground granulated blast-furnace slag (GGBFS) as a small part of the binder.

TL;DR: In this paper, the effect of different proportions of ground granulated blast-furnace slag and activator content on the workability and strength properties of fly ash based geopolymer concrete was evaluated.

TL;DR: In this article, a small proportion of ordinary Portland cement (OPC) was added with low calcium fly ash to accelerate the curing of geopolymer concrete instead of using elevated heat.

TL;DR: In this article, the authors investigated the properties of blended low-calcium fly ash geopolymer concrete cured in ambient condition, and they found that the density of hardened GPC mixtures is similar to that of normal-weight OPC concrete.

TL;DR: In this paper, the authors investigated the effect of fly ash as a supplement to concrete and found that the fly ash concrete samples showed less drying shrinkage than control concrete samples when designed for the same 28-day compressive strength of the control concrete.
