Process-reliable production of adhesive-bonded timber-concrete composite components- SafeTeCC

Adhesive-bonded timber-concrete composite components, in which precast reinforced concrete elements are used instead of in-situ concrete, can be consistently implemented on the construction site as a "dry element". This preserves the advantages of classic timber construction, such as rapid construction progress and low moisture input, while at the same time improving the load-bearing and deformation behavior of the slab elements. However, with regard to process-safe and bonding and the test methodology for determining the durability of the composite, there are still some unanswered questions that currently inhibit its application in construction practice.
The aim of the research project is to manufacture large composite components made of timber and concrete in a process-reliable manner and to be able to make a reliable statement on the durability of the bond. Reference is made to existing normative specifications and the thermal-hygric behavior of the materials timber, concrete and adhesive is taken into account. For this purpose, different manufacturing processes such as continuous and discontinuous bonding, grouting and the casting of recesses present in the precast concrete element are considered.
