Study-Unit Description


TITLE Degradation of Building Materials 2

LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course


DEPARTMENT Metallurgy and Materials Engineering

DESCRIPTION This study-unit covers coursework related to the degradation of construction materials, specifically metals (steel, copper, aluminium and their respective alloys), polymers, glass, ceramics and bituminous products. Ways of mitigating the degradation phenomena are also briefly discussed. The emphasis of course material will be on electrochemical corrosion phenomena.

Study-unit Aims:

This study-unit aims to provide a basic understanding of:

- Aqueous corrosion processes pertaining to a number of important metals employed in the construction industry;
- Physico-chemical degradation of ceramics, glass and polymeric materials used in building and construction.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:

- Explain basic terminology and concepts related electrochemical corrosion of metals;
- Describe conditions that potentially lead to accelerated/uncontrolled corrosion in metals e.g. pitting and crevice corrosion;
- Outline basic methods of mitigating aqueous corrosion degradation in metals;
- Explain basic physico-chemical processes leading to the degradation of the following non-metallic materials: glass, ceramics and organic polymers.

2. Skills:

By the end of the study-unit the student will be able to:

- Utilize a simple thermodynamic Potential-pH diagram to predict corrosion of metals in a given corrosive environment;
- Recognise the different types of electrochemical corrosion processes and correlate them with metallurgical and environmental factors;
- Implement appropriate measures of material selection/protection at design stage to reduce/limit future failure by corrosion degradation.
