What is Thermal Simulation in Concrete Technology?

3D simulation is a computer-based method for representing and analyzing physical processes and structures, crucial in construction and engineering for precise thermal modeling in concrete. It is a specialized form of thermal simulation that takes into account the unique properties and behavior of concrete during production, installation, and use phases.
The concrete technological thermal simulation refers to the modeling and analysis of heat generation and thermal behavior of concrete throughout its lifecycle, particularly in connection with the curing process and temperature control. Predicting Structural Changes Before Execution: Anticipating potential alterations in a structure before construction helps to avoid unexpected issues during the building process. Monitoring Deflections, Temperature Changes, and Cracking: Simulations can predict deflections under loads, temperature variations, heat development, and potential cracking or failure in concrete, allowing for preemptive adjustments. Enhancing Design and Preventing Future Problems: By identifying these risks early, simulations aid in refining the design and implementing preventive measures, ensuring long-term durability and reliability of the structure.

Why are simulations necessary?

Especially for all constructions qualified as mass concrete, a maximum crack width is often specified. This cannot be achieved with the conventional construction method
  • Utilizing Simulations During the Design Stage: Simulations should be employed early in the design process to identify potential issues, allowing for rectifications and the achievement of optimal solutions before construction begins.
  • Prevent Disastrous Consequences in Mass Concrete: Address temperature changes, shrinkage, and load-induced stresses to avoid significant issues during and after construction.
Core Benefits
  • Enhance Safety: Improve structural integrity by predicting and minimizing temperature-induced cracking, enhancing durability, and preventing catastrophic premature failures.
  • Reduce Costs: Avoid costly repairs of cracks and reduce downtime by proactively addressing thermal stress during the construction phase.
  • Increase Sustainability: Extend the structure’s service life by reducing degradation, and lower carbon emissions through optimized material use and decreased maintenance needs.

At Concrefy, we integrate advanced 3D simulation technology into both the planning and execution phases of concrete construction to enhance project outcomes. By combining advanced simulations with real-time monitoring and expert guidance on-site, we ensure that concrete structures meet stringent quality standards, resulting in enhanced performance and longevity.

At Concrefy, we combine our deep expertise in concrete technology with advanced stress simulation software to offer customized guidance for managing cracks caused by hydration heat in young concrete. Young concrete behaves differently during the hardening process compared to fully hardened concrete, increasing the complexity of structural models.

  • The exothermic reaction in young concrete leads to heat development.
  • The heat distribution in concrete varies based on environmental factors.
  • Variation in heat distribution causes uneven expansion and strain in the concrete.
  • Structural boundary conditions add additional restraint, leading to imposed stresses. The mechanical properties of concrete that provide resistance to these stresses develop gradually over time.
  • The imposed stresses can exceed the mechanical tensile strength, leading to the formation of cracks.
Simulations provide the opportunity to assess multiple scenarios before the start of work and map out their effects on concrete, reinforcement, cooling or insulating the concrete, pouring schedule, reinforcement configuration, and the risk of stress/cracking. Utilizing state-of-the-art software like DIANA FEA, we create detailed virtual models to predict temperature changes, shrinkage, and load-induced stresses in mass concrete structures. This approach allows us to assess multiple scenarios, optimizing concrete mixtures, reinforcement configurations, cooling or insulating strategies, and pouring schedules to effectively control cracking due to hydration heat.
  • Real-Time Monitoring with Concremote: During construction, we employ Concremote sensors to monitor actual conditions in real-time. This data enables immediate adjustments to maintain optimal curing conditions, ensuring the concrete achieves the desired strength and durability.
  • On-Site Expertise: Our concrete technologists provide customized mixture recommendations and detailed execution strategies. With our mobile lab, we guide the hardening process on-site, conducting immediate testing and interventions as necessary.
