Achieving high load-bearing capacities with specific joint geometries

Gluing structural components made from fine-aggregate concrete

In the wake of the development of high-performance and ultra-high-performance concrete, as well as novel types of glass-fiber, carbon or micro-reinforcements, engineers embarked on designing and constructing structural components or entire structural frameworks composed of such components that were as slender and thin-walled as possible. This endeavor is associated with the inevitable question of identifying the most appropriate joining method. Minimum spacings must usually be adhered to when connecting elements via mechanical, punctiform fasteners, which requires a corresponding increase in...
