1. Durability of loaded structures of cement-fibre composites with concrete and brick recyclate against action of environment and chemical substances

   The thesis will analyze durability of cement-fibre composites with concrete and brick recyclate on basis of permeation and diffusion tests. The aim is to prove positive influence of fibres together with a complete formulation of composite with and without loading on absorption of aggresive substances and thus on durability. More general aim is to propose a methodology of the estimate of durability of cement-fibre composites with recyclates on basis of analysis of formula and of its components.

2. Prediction of the durability of eko-friendly composites with cement matrix from the results of mechanical, physical and physical-chemical tests

   The proposed topic is focused on optimization of the methodolody of estimating the durability of concretes with wood residues content. Pore structure of concrete is of primary importance for its durability. The pore structure of concrete can described by a number of tests but not all of them are a suitable indicator of durability. The expected output are complex conclusions with an impact on the objectivity of using the test of concrete pore structure in relation to the estimate of durability.

3. Study of physical-mechanical and durability characteristics of construction fibre concretes with use of alternating waste fibres

   Both organic and anorganic fibres from waste raw materials can be used purposefully in construction fibre concretes with extracted aggregate and concrete recyclate. The comparison of physical-mechanical and durability characteristics of fibre concretes with and without loading can contribute to estimating lifetime and ductility behaviour of fibre concretes of different formulations.
