Contractors can predict the potential result of a concrete flow through the maturity method, but it may be difficult to apply this technique to the field. That is why Heidelberg Materials, one of the largest cement suppliers, aggregates and prefabricated and prepared concrete, provides its customers HETT22, a compiled simulation application that provides timely access to multi -drug -based forecasts. HETT22 and its associated models were created for Heidelberg Materials for Deflexional, a Consultant Comsol that specializes in using the Comsol Multiphysics® Software to create Multiphysian models and simulation applications. In just six months after the launch, HETT22 was downloaded more than 1100 times.
“HETT22 helps you evaluate options from different perspectives,” said Mikael Westerholm, responsible for the Heidelberg Materials Sverigeg Sverigeg Serige program project. By predicting the potential results of the early age maturity process, contractors may be more secure in the options they take on the alternatives of construction, before their decisions are in stone.
Although several factors may affect the maturity and development of concrete strength, the temperature plays a particularly significant role. The concrete that is quickly cured in hot weather is likely to be weaker than the concrete that ripens more slowly in colder conditions. Temperatures below freezing may also affect the development of force. Contractors can isolate the formwork to mitigate the risks of freezing or add heat from external sources. These techniques must be applied judicially to prevent overheating, premature drying or significantly increase the costs of the construction project.
Put the multifistic simulation into the hands of the contractors
HETT22 is the first generation of the program that will be developed through the application builder in Multiphísica Comsol and distributed as an application of autonomous simulation.
“With HETT22, one of our goals was to be as easily to use possible,” said Tom Fredvik, technical head of the Heidelberg Materials Norge. “We have also added new features that allow our customers to take into account the real world conditions in more detail.”

A brief journey of a hypothetical concrete casting project demonstrates the capabilities of HETT22 (Figure 1). The application user begins by selecting a list of typical cases, and then defines the flowing geometry parameters, the mixture of materials, the concrete force, the term and the expected weather conditions.
After defining formwork and geometry, the user can integrate the specific weather forecasts of the site for the expected casting. Time restrictions and desired strength are key influences in choosing a user’s materials. “In this example, the strength requirement is set at 15 MPA before being able to eliminate the formwork,” said Westerholm, “so we choose a concrete with a proper force development of the pre -installed library.”
Simulation results Guide Preventive Adjustments
With the models that feed the application, HETT22 produces predictive values to determine how long it will take the desired force before the removal of the form. “We can keep track of the expected temperatures for the air and the surrounding soil and foresee a temperature curve for the concrete itself,” said Fredvik. (Figure 2) “From our development of temperature, we can calculate that it will take about 30 hours to the entire casting to achieve the force we need.” If this is too long for this work, HETT22 can show the potential effect of different concrete selections on the estimated time for the removal of the form. Builders can select different options between a menu of materials from Heidelberg Materials, as well as review the details on the performance features of each option directly in the simulation application.

Multifistic simulation supports cost -Benefici
Polaring the effects of options related to physical conditions, a construction equipment can use a compiled simulation application to better manage the economy and carbon footprint of each project.
Heidelberg offers its customers hundreds of potential concrete recipes; From the perspective of the company, the application is a complement necessary for a range of potentially unpleasant options. The predictive modeling capacity of Multiphysics Comsol software, when presented through the custom interface of the application, helps users to make informed decisions more efficiently.
“That is why we provide HETT22 to our customers,” Fredvik said. “Due to the value that adds to each point of decision -making of a specific casting job, we see it as a fundamental part of our offer of technological support.”
