- Insights into material design, extrusion rheology, and properties of 3D-printable alkali-activated fly ash-based binders (2019, background): “…was found to cause extensive microcracking in the F 50 S 30 L 20 and F 50 S 30 L 19 A 1 mixtures due to the high shrinkage of slag-containing alkali activated binders [69,70], thereby leading to poor flexural strength (microcracking influences flexural strength more than the compressive strength).”
- Mechanisms of autogenous shrinkage of alkali-activated slag and fly ash pastes (2020, background): “[16], who claimed that the autogenous shrinkage of AASF mortar occurs mainly due to self-desiccation in the hardened state rather than the volume contraction converted from the chemical shrinkage in the fresh state.”
- Effect of slag content and activator dosage on the resistance of fly ash geopolymer binders to sulfuric acid attack (2018, background): “C-N-A-S-H is a hybrid of C-A-S-H gel which is formed in slag systems [66] and N-A-S-H gel which is formed in fly ash systems [67].”
- Assessing the porosity and shrinkage of alkali activated slag-fly ash composites designed applying a packing model (2016, result): “This result is in accordance with the previous investigations that reducing the slag content in the slag-fly ash blends will lead to a decrease of drying shrinkage [54,55].”
- A Review of Recent Developments and Advances in Eco-Friendly Geopolymer Concrete (2020, result): “[150] studied the shrinkage characteristics of alkali-activated FA-slag (AFS) GPC and showed that AFS paste shows higher drying shrinkage than OPC due to presence of large mesopore volume in AFS paste as compared to OPC paste.”
- Fiber-reinforced geopolymer composites: A review (2020, methodology): “To control the drying shrinkage, two approaches have been often followed: (1) the modification of the pore structure to minimize capillary porosity and to control water loss during curing [141], and (2) the inclusion of inert or reactive fillers and fibers [142].”
