Entwicklung eines hochwärmeleitfähigen Betons unter Verwendung von mikroarmierenden Kohlenstoff-Verbundwerkstoff-Füllstoffen (C/C-Komposite)
Bachelor thesis, Master thesis
Description
The objective of this study is to develop a formulation for specialized thermally conductive concrete for use in energy infrastructure construction. The concrete is intended to exhibit high thermophysical and mechanical properties. A processed carbon composite material is used as the primary functional filler, which is expected to both establish a thermal conduction pathway and provide micro-reinforcement of the matrix. Currently, manufacturers use up to 8% natural graphite in thermally conductive concretes.
Research Tasks
Optimization of particle size distribution:
Determination of the optimal ratio between aggregates and the carbon filler to achieve maximum packing density.
Rheological analysis:
Determination of the optimal dosage of additives to ensure high flowability (consistency class F4/F5) while maintaining mixture stability (prevention of segregation).
Thermophysical testing:
Measurement of thermal conductivity (lambda) under various conditions. Determination of specific thermal resistance.
Mechanical testing:
Determination of compressive strength.
Measurement of flexural tensile strength to evaluate the contribution of the composite’s fiber structure to the reinforcement of the material.
