Cement-based materials encompass a broad spectrum of construction materials that utilize cement as the primary binding agent. Among these materials, concrete stands out as the most commonly employed. The cement, which is the principal constituent of these materials, undergoes a hydration reaction with water, playing a crucial role in the formation of the hardened composite. However, the exothermic nature of this reaction leads to significant temperature rise within the concrete elements, particularly during the early stages of hardening and in structures of substantial thickness. This temperature rise underscores the critical importance of predictive modeling in this domain. This paper presents a review of modeling approaches designed to predict temperature and accompanying moisture fields during concrete hardening, examining different levels of modeling accuracy and essential input parameters. While modern commercial finite element method (FEM) software programs are available for simulating thermal and moisture fields in concrete, they are accompanied by inherent limitations that engineers must know. The authors further evaluate effective commercial software tools tailored for predicting these effects, intending to provide construction engineers and stakeholders with guidance on managing temperature and moisture impacts in early-age concrete.

“…Similar to the DIANA FEA software, the determination of moisture fields is not possible with MIDAS. The state of the art shows that the application of MIDAS is usually limited to determining the temperature field in the concrete caused by the hydration heat, particularly in bridge components [48,143,144].…”

“…Notably, the literature [28] presented a case study involving real-world application of these methods alongside on-site measurements, underlining the practical implications and limitations of each approach. Klemczak, Knoppik-Wróbel [30], and Li et al [31] presented case studies, the former detailing the construction of a mass concrete tunnel in Shantou City, China, and the latter discussing the behavior of tank walls and bridge abutments. Both highlighted the importance of understanding thermal-shrinkage mechanisms and showcased successful mitigation techniques, such as gradient concrete and plastic anti-crack grids.…”

The drive for continuous innovation in large-scale infrastructure necessitates advancements in techniques, addressing the challenges of constructing super-length concrete structures. This study investigated the emerging shift from traditional united expanding agent (UEA) to magnesia expansive agent (MEA) in conjunction with expansive strengthening bands (ESBs), marking a pivotal transition in ensuring monolithic integrity. Despite a decade of exploration, MEA–ESB implementation in real-world projects remains underdocumented, with scholarly focus primarily confined to material characterization. This research integrated empirical on-site tests of MEA–ESB with high-fidelity numerical simulations in ABAQUS. The finite element model (FEM) validation against actual test data underscored the precision of our modeling, capturing the complex thermomechanical behavior of the system. We introduced a sophisticated parametric analysis framework, elucidating the influence of critical parameters like the ESB-to-raft-width ratio and MEA concrete expansion rates. This granular understanding facilitated the fine-tuning of design parameters, advancing the practical application of MEA methodologies. A groundbreaking contribution entailed the formulation of predictive models for early-stage cracking, anchored in the guidelines of the ACI Committee 207 and refined through extensive parametric exploration. These formulae empower engineers to anticipate and mitigate cracking risks during the design phase, thereby enhancing project safety and efficiency. Notably, this study identified limitations in current prediction models, highlighting the need for future research to incorporate comprehensive lifecycle considerations, including hydration heat effects and time-dependent mechanical property evolution.

“…Optimizing aggregate grading or using aggregates with higher heat storage capacity, such as basalt aggregates, can also effectively reduce concrete temperature. When controlling temperature differentials within concrete, factors such as the arrangement of cooling systems, ambient temperature, and pouring temperature need to be considered for their effects on the internal temperature field of concrete [24]. Smolana and others [25,26] discussed some analytical and numerical methods for assessing early-age cracking risks, predicting temperature field, and implementing appropriate protective measures, which contribute to the normal use and durability of concrete structures.…”

In engineering practice, similar surface insulation measures are typically applied to different parts of mass concrete surfaces. However, this can lead to cracking at the edges of the concrete surface or the wastage of insulation materials. In comparison to flat surfaces, the edges of mass concrete structures dissipate heat more rapidly, leading to more pronounced stress concentration phenomena. Therefore, reinforced insulation measures are necessary. To reduce energy consumption and enhance overall insulation effectiveness, it is essential to study the specific insulation requirements of both the flat surfaces and edges of concrete separately and implement targeted surface insulation measures. Taking the bridge abutment planned for pouring in Nanjing City as the research object, this study established a finite element model to explore the effects of different ambient temperatures and different surface heat dissipation coefficients on the early-age temperature and stress fields of different parts of the abutment’s surface. Based on simulation results, reasonable heat dissipation coefficients that meet the requirements for crack prevention on both the structure’s plane and edges under different ambient temperatures were obtained. The results indicate that under the same conditions, the reasonable heat dissipation coefficient at the edges was smaller than that on the flat surfaces, indicating the need for stronger insulation measures at the edges. Finally, mathematical models correlating ambient temperature with reasonable heat dissipation coefficients for the structure’s plane and edges at these temperatures were established, with high data correlation and determination coefficients (R2) of 0.95 and 0.92. The mathematical models were validated, and the results from finite element calculations were found to be consistent with those from the mathematical models, validating the accuracy of the mathematical models. The conclusions drawn can provide references for the insulation of similar engineering concrete planes and edges.
