Rheologische Messungen an Baustoffen 2019

More about the book

Rheological measurements are essential for optimizing the application of building materials, and applied rheology has gained significant attention in civil engineering. Advanced testing equipment and extensive research have enhanced understanding in this area. Conferences, like the 28th Conference on the Rheology of Building Materials at OTH, have facilitated the exchange of findings and fostered valuable connections. A key focus has been finding a balance between rheological theory and practical application. The proceedings address crucial topics, including specific applications of concrete such as self-compacting concrete, tremie concrete, and mortar mixes for 3D printing. Understanding time- and temperature-dependent changes in workability is vital for successful material application. Additionally, the mixing energy and casting/spraying methods significantly impact rheological properties. The rheology of concrete types can vary greatly due to compaction methods like vibration. While testing pastes is simpler, it raises questions about the applicability of paste measurements to concrete assessment and how to determine optimized paste content. Furthermore, the role of admixtures and additives in improving various application processes is explored, highlighting the effectiveness of superplasticizers, stabilizers, and entrained air in influencing rheology.
