“…The maximum heat release peak time was not affected by the presence of 0.5% NPAM and 0.5% CPAM, as compared with the control groups. The addition of PAM enhanced the bonding and manipulability of 3D‐printed cement‐based composites 147 . Similar study investigated the correlation between the quality of layers and the microstructure in 3D‐printed cementitious materials, which were produced for different durations & demonstrates that the rheological properties of the paste increase with time.…”

This paper offers a thorough unfolding of the many contributions that water‐soluble polymers (WSPs) play in cementitious composites. The several forms of WSPs—natural, semi‐synthetic, and artificial—are examined, and their methods of action in cementitious composites are investigated. The topics of binding, association, adhesion, complexation, and bridge creation are covered in the literature. The effects of WSPs on the microstructure, freshness, mechanical properties, and durability of cement‐based goods are also investigated in this review. The advantages and disadvantages of utilizing WSPs in cement‐based products are also discussed. Following a detailed analysis of the most significant findings, recommendations are made for both academic and practical research areas and applications. This study provides useful information for both experts and novices by elucidating the multi‐applications of WSPs in cementitious materials.

“…The retarding effect of polymers on cement hydration is consistent with the magnitude of their charge density, with higher charge density polymers having stronger retarding effects on cement hydration. In addition, polymers with anionic or cationic surface charges have a stronger adsorption capacity on cement surfaces than nonionic emulsions, thus having stronger inhibitory effects on cement hydration [ 9 ]. Different polymers have different functional groups that form different coordination bonds with hydration products, and different functional groups have different effects on hydration reactions.…”

Due to its large volume and poor thermal conductivity, mass concrete is prone to temperature cracking caused by heat release during cement hydration after pouring. To address the issue of temperature cracking in mass concrete, this study utilized emulsion polymerization to prepare polybutyl acrylate (PBA) emulsions. At an optimal dosage of 1.5%, the addition of a PBA emulsion reduced the temperature rise of cement paste by 12.4%. The inhibitory mechanism of a PBA emulsion on cement hydration was analyzed by characterization techniques such as isothermal calorimetry, X-ray diffraction Rietveld full-profile fitting method (XRD), thermogravimetric–differential scanning calorimetry (TG-DSC), and mercury intrusion porosimetry (MIP). The results showed that the C3S content in the cement specimens with 1%, 1.5%, and 2% PBA increased by 13.83%, 23.52%, and 34.65% compared to the blank group, respectively, while the C3A content increased by 92.59%, 79.63%, and 96.30%, respectively. The addition of a PBA emulsion can slow down the hydration rate of C3S and C3A, thereby reducing the temperature rise and fall rate of cement hydration, reducing the peak heat release of the hydration reaction, and ultimately achieving the inhibition of the cement hydration reaction. In addition, the mechanical properties of PBA-modified cement-based materials were also tested. The results show that the addition of PBA can affect the early strength development of cement samples, but has no effect on the strength after 60 days. Therefore, PBA can be used as a hydration temperature rise control material to reduce the risk of temperature cracking in mass concrete.
