“…It was emphasized that the PCE requirement decreased with the use of fly ash (Ng & Justnes, 2016). Similar results were found by Altun et al (2021) for mixtures containing up to 30% fly ash.…”

“…Similarly, in another study by Altun, (2021), it was emphasized that the flow value of the mixtures increased with the increase in the fly ash utilization ratio. At the end of 60 minutes, it was determined that the mixtures containing 2% HRWRA had the highest consistency retention capacity, regardless of fly ash fineness and utilization ratio.…”

At the same time, polyethylene oxide side chains provide steric hindrance (Altun et al, 2021;Ozen et al, 2021;Sahin & Mardani., 2022d;Mardani-Aghabaglou, 2021a;Ozen et al, 2020b;Ozen et al, 2022b;Mardani-Aghabaglou, 2021b).…”

“…At the end of 60 minutes, it was determined that the mixtures containing 2% HRWRA had the highest consistency retention capacity, regardless of fly ash fineness and utilization ratio. It was stated by the researchers that the adsorption of the negatively charged carboxylate molecules on the surface of the fly ash particles is quite low since the fly ash surface is negatively charged (Altun, 2021;Wang et al, 2021;Cangialosi et al, 2009). Thus, the cement surface is covered with more waterreducing admixture molecules and the consistency retention capacity of the mixtures increases (Wang et al, 2021).…”

“…The other mechanism was reported to cause the mixture to solidify faster by absorbing free water as a result of the porous structure of rice husk ash. It was emphasized that the setting time of the mixtures is increased with the utilization of water‐reducing admixtures, but the compressive strengths of 7 and 28 days are positively affected 49–53 . However, it was reported that the use of setting retarder admixtures caused a decrease in the 1 and 7‐day compressive strength values of the mixtures but did not have a significant effect on the 28‐day strength performance 32 .…”

In this study, the strength and durability performance of 3D printing concrete mixtures (3DPC) were examined in terms of the materials used in their production and printing process parameters (interlayer interval time, printing speed, and nozzle shape). Due to the anisotropic nature of 3DPC, it was understood that the compressive strength depends on the loading direction. It was emphasized that it is necessary to control the shrinkage behavior of 3DPC mixtures due to the lack of formwork and the high dosage of binders. It was reported that the interlayer adhesion of 3DPC is highly dependent on the interlayer interval time and printing speed parameters. It was understood that nozzle shape and standoff distance affect the mechanical properties and surface roughness of 3DPC specimens, and this effect is more pronounced in mixtures with high static yield stress values.

Concrete is a valuable construction material with high mechanical strength and durability, used extensively in the construction industry. It is produced by mixing sand, stones, cement, and water in different proportions depending on the desired quality of the final product. Water reducers are additional chemical ingredients used in concrete to reduce the quantity of water required in the concrete mixture. When added to concrete, water reducers increase the workability and flowability of concrete in the freshly mixed state and improve the mechanical strength and durability of the final hardened product. This review paper describes the different types and applications of concrete water reducers used in the construction industry including their working mechanisms and fluidity effects on concrete properties. It discusses the production of synthetic and bio‐based concrete water reducers and reviews the present challenges involved in the preparation of bio‐based concrete water reducers from renewable resources. © 2023 Society of Industrial Chemistry and John Wiley & Sons Ltd.
