The construction sector has been addressing the issue of integrating sustainability into
production processes over the last few years, either through solid waste materials as …

Many alkali-activated materials (AAMs) exhibit poor workability in mixing owing to great
viscosity of the paste and fast setting. Chemical admixtures commonly used in Portland …

Fly ash geopolymer is an emerging alternative binder with low environmental impact and
potential to enhance sustainability of concrete construction. Most previous works examined …

The highly viscous property of alkali silicate-activated cements is one of the critical
challenges that hinder their wide application. The present study focuses on ameliorating the …

The effects of ground granulated blast furnace slag/fly ash (GGBFS/FA) ratio, mass ratio of
SiO 2 to Na 2 O (M s) of activator solution and sodium silicate dosage on structural build-up …

If formulated optimally, geopolymer cement made from fly ash, metallurgical slags and
natural pozzolans could reduce by 80% the CO2 emissions associated with the …

The objective of this paper is to study the flow and viscoelastic properties of fly ash-based
geopolymers activated at different concentrations of NaOH. Although the investigated …

This paper evaluates the effect of different commercial superplasticizers (SPs) such as
naphthalene, melamine and modified Polycarboxylate based on the workability and strength …

The emerging concept of 3D concrete printing (3DCP) by the laminate stacking of layers
without formwork has major issues of poor interlayer bond adhesion and inadequate …

Sulfate attack is recognized as a significant threat to many concrete structures, and often
takes place in soil or marine environments. However, the understanding of the behavior of …
