Materiais de Protecção, Reparação e Reforço

Objectives

Aims at the understanding the scope, problems involved, criteria and methodology required for the conservation, restoration and rehabilitation of old buildings in comparison with similar operations in contemporary constructions, through discussion of fundamental concepts and case studies analysis, with the aim of developing specific skills to intervene within pre- existent contexts with historical and cultural value. Provide students the ability to integrate and work in multidisciplinary teams within the scope of Built Heritage with because interventions in this type, since in this field it is mandatory the collaboration of various scientific areas and the use of materials, techniques and constructive solutions that guarantee compatibility with the ancient construction. Provide students with knowledge within the mechanisms and forms of alteration and degradation of traditional and contemporary materials and the materials and solutions for protection, repair and reinforcement.

Syllabus

Concepts and criteria related to cultural heritage, conservation and restoration. International charters and conventions. Compatibility of pre- existences with contemporary interventions and new materials. Importance of prior knowledge of pre-existences. Principles and methodology in conservation actions. Materials and construction techniques evolution; traditional masonry structures. State of conservation. Intrinsec and extrinsic causes of degradation, mechanisms and forms of degradation: masonry, mortar, stone, glazed tile, wood, metallic materials, reinforced concrete. Traditional and contemporary materials and solutions for repair, protection and strengthening: cleaning, desalination, hydrofugation, control of organic growth, direct and non direct protection of metal and other materials, consolidation, replacement and reintegration materials, strengthening materials. Burning behaviour of materials and solutions for fire protection of structures: reinforced concrete, steel, timber.

Prerequisites

Attendance of the following subjects/courses: General Chemistry (LEC) and Construction Materials I (LEC)

Cross Competence Component

The CU allows the development of transversal competences on Critical Thinking, Critical Thinking, Strategic Thinking, Problem Solving Strategies, Decision Making, and Social and Civic Responsibility through the analysis and discussion of case studies during the lessons and within the assessment components with the aim of identifying problems, possible causes and solutions for their resolution, selection the solutions with the best performance and potential contribution for the environmental sustainability and preservation of cultural values. The assessment percentage associated with these competences should be around 25%.

Ethical Principles

All members of a group are responsible for the group's work. In any assessment, every students shall honestly disclose any help received and sources used. In an oral assessment, every students shall be able to present and answer questions about the entire assignment and solution.
