INTRODUCTION TO BUILDING MATERIALS
Classification and applications. Basic properties. Testing as study basis. Acceptance and research testing. Non-destructive testing. Result accuracy.
METALLIC MATERIALS: Steel. The most important application in Civil Engineering: reinforcement. History of steel production including Blast Furnace. Blast Furnace raw materials, pig iron production and the by-product slag and its applications : the by-products: slag, charge, applications. Pig iron, properties and applications. Steel refining. Present steel production in electric arc-furnace steel works. Environmental issues and steel production. Continuous casting and lamination. End products and product qualification. Steel production in SN (Maia): scrap as raw material, scrap yard, basket transporters, furnace feeding, arc furnace, scrap fusion, oxygen and coke feeding, steel and slag production, ladle furnace, refining, continuous casting, lamination, end products. Steel treatment. Tempcore. Prestressing steel – production: pickling, phosphating, wire drawing and stabilization. LNEC E452 specification. Properties and tests. Mechanical tests. Steel tensile test. Standard equipment. Classification of steel. NP EN 10002 standard.
Toughness and resilience. Strength and ductility indicators. Hardness testing: Shore, Brinell, Meyers, Vickers and Rockwell. NP EN 10 003-1 standard. REBAP and REAE (Reinforced concrete and steel structures standard in Portugal). Bending test. NP173 and requirements (REBAP, REAE and Eurocode). Steel fatigue and tests. Types of tests. Steel corrosion. Anodic and cathodic reaction. Consequences of corrosion. Types of corrosion –pitting, general and stress corrosion. Steel normalization – REBAP, REAE, EC and specifications of the LNEC referring to concrete reinforcement: E449, E450, E455 and E460 specifications.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
Several curricular units of the course lead to a set of knowledge and skills that allow the calculation and determination of the respective levels of stress and strain installed in a structure. This curricular unit provides knowledge and skills on some of the most widely used materials that can support these stresses, materializing and making the structure a reality.
This course will be based on theoretical presentations of essential concepts related with construction materials and their practical applications. It will be carried laboratory assignments, where students can work with steel, aggregates and wood, in order to acquaint students with techniques that will make them able to choose the proper materials for different applications of civil engineering.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Beyond the knowledge and understanding of the behavior of materials subjected to various actions, the teaching methodologies provide knowledge on current technologies to enable use of these materials and following existing technical standards for proper use of these materials in construction.

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the class types is not exceeded.
ASSESSMENT
The Final grade is based on distributed assessment with no final exam. Distributed assessment consists of two tests T1 and T2. These tests are compulsory and each one corresponds to 50% of the final grade.
The final grade, CF results from the following formula:
CF=CT1×50%+CT2×50%
Where
CT! is the grade obtained in T1 which will take place on Wednesday, 14th November
CT2 is the grade obtained in T2 which will take place on the date scheduled for the "Normal exam"
Note 1: All students enrolled in the current academic year shall be assessed with this method.
Note 2 : In the Appeal Season the student enrolled in the current year, may choose one of the following situations:
i) Repetition of test T1
i) Repetition of test T2
(iii)Total exam including subjects related to T1 and T2.
NOTA 3: In the appeal Season, the improvement exam corresponds to the WHOLE of the subjects
