Informace k předmětu:

Information on the course

The next lecture: 2pm October 18 (room A229)
The next lab: 4pm October 11 (room Ds162)

The course schedule and basic information on the course 123 MED is available here.

A written test (30 %)
A presentation of a topic concerning materials engineering (30 %)
Laboratory reports (40 %)
Participation in laboratory exercises - only one absence is allowed.

There are two written tests. Both will take place at the end of term.
One test (about 15 min) is for credit assessment, and it will contain questions concerning lab exercises.
The other test (about 30 min) is a 30 % part of the grading (see above), and it will contain questions concerning topics from lectures.

Lectures are not mandatory.

  • Basic properties of materials: bulk density, matrix density, relative density, porosity, gravimetric and picnometric methods, gas adsorption porosimetry and mercury intrusion porosimetry (presentation)
  • More coming soon.

Laboratory exercises

Be aware that only one absence in laboratory exercises is allowed.

1. Introductory exercise – work safety, basic rules of laboratory work safety, standard laboratory protocol, visiting of laboratories.
Presentation: Introduction

2. Basic properties of porous building materials - experimental determination of bulk density, matrix density, vacuum saturation moisture content, total open porosity – gravimetric method, vacuum saturation method, pycnometric method.
For further information see: here
Presentation: Basic physical properties

3. Water vapor transport - cup method (wet/dry), measurement of water vapor diffusion coefficient and water vapor resistance factor.
+ Liquid moisture transport - experimental determination of water absorption coefficient and apparent moisture diffusivity
For further information see: here
Presentation: transport of liquid water and water vapor

4. Thermal properties of building materials – assessment of thermal conductivity, specific heat capacity, thermal diffusivity for dry materials as well as in dependence on moisture content rising
For further information see: here
Presentation: heat transfer

5. Dynamic viscosity of fluid, newtonian fluid, non-newtonian fluid, Stokes law, measurement of viscosity of chosen liquids.
+ Working with microscope - samples preparation, texture of building materials
For further information see: here
Presentation: viscosity
