Objetivos

Provide technical-scientific knowledge in the field of building materials, namely natural stone, cement and additives, mortars, concrete, ceramics, woods, metals, polymers, composites and new construction materials, through the analysis of raw materials, processing, properties and their evaluation, mechanisms of deterioration, applications and normalization applied. Special attention will be given to materials used in conservation and rehabilitation operations and compatibility between materials. Provide students with knowledge and skills related to the experimental / laboratory activity.

Métodos de ensino e atividades de aprendizagem

In TP classes the fundamental concepts will be taught by exposure, using audiovisual means and some illustrative problems of these concepts will be discussed. In the more practical classes, the students will individually solve exercises proposed by the teacher. Part of the teaching activities will be taught in laboratory classes where the students participate, in group, making sure that, in applying the acquired knowledge, they develop laboratory skills.

The teaching / learning methodology comprises, in the case of continuous assessment, participation (10%), 1 individual written test (1x50%), 2 laboratory group works (1x10% + 1x30%).

In the case of the 1st and 2nd exam periods, the teaching / learning methodology comprises an exam (60%), 2 laboratory group works (1x10% + 1x30%).
