Project "CEMWOGEO"

Cement coating of wood for geotechnical applications
Subproject 1: Cement treatment of wood - process engineering development and characterization

Background and Content

The CEMWOGEO project builds on previous research work in which a laminated veneer lumber tube has already been developed as an anchor bar in foundation engineering and as a resource-saving alternative to steel. This is to be further developed, with a particular focus on increasing durability. To this end, the interaction of cement and wood and the durability of the material combination will be investigated. By developing an innovative cement treatment for wood and wood-based materials, which will be accompanied by field tests and durability analyses, the project team is developing the basis for increased use of wood and wood-based materials in geotechnical engineering, e.g. for foundation measures and slope stabilization of buildings and infrastructure constructions, but also in other areas.

Project Goal

The aim is to provide structural and civil engineering with an expandable building product for structural applications. The new material combination of wood or wood-based materials and concrete meets all the requirements for strength and durability, but offers significant advantages over steel, which is comparatively expensive and resource-intensive to manufacture.

In the first step, the partners are investigating the possibilities of filling the laminated veneer lumber pipe with concrete to ensure its durability. By changing the pipe diameter and wall thickness, product variants can be created that can be used in various areas. Last but not least, the results of the CEMWOGEO project will also provide a basis for the development of future solutions for the rehabilitation of timber piles.

Cooperation

Under the leadership of the TH Rosenheim, scientists from various disciplines are working closely together in the CEMWOGEO project:

  •     University of Göttingen and TU Munich with Wood Research Munich for the field of wood technology as project partners.
  •     University of Innsbruck, material sciences, especially in the field of concrete and shotcrete technology
  •     Graz University of Technology, soil mechanics, especially in the field of special civil engineering
  •     Rosenheim Technical University of Applied Sciences mainly in the field of wood technology and civil engineering
