High-volume natural volcanic pozzolan and limestone powder as partial replacements for portland cement in self-compacting and sustainable concrete (2014, background): “The apparently reduced drying shrinkage of the concrete with increased NP may be related to the refinement of pores through pozzolanic reaction, which obstructs water evaporation [58], and also a higher amount of unreacted ash, which could act as aggregate that restrains shrinkage [59].”
Self-compacting concrete with different levels of pulverized fuel ash (2010, background): “In order to extend the concept of HVFA concrete to SCC, some investigations have been made on SCC incorporating more than 50% fly ash [7–13] but there has been little systematic work on SCC with higher fly ash content to date.”
Effect of Fly Ash on the Durability Properties of High Strength Concrete (2011, background): “Fly ash in concrete reduces drying shrinkage (Atis 2003), thus generates fewer cracks which ensure greater resistance to deterioration.”
An experimental study on flexural strength of reinforced concrete beams with 100% recycled concrete aggregate (2014, background): “Consequently, many researchers have investigated the use of recycled materials in the production of concrete such as fly ash [1–7] and recycled aggregate [8–17].”
