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.
WOOD: Introduction. Wood use – advantages and disadvantages. Softwood and hardwood. Species. Production. Physical and mechanical properties of wood – Introduction. Standards. Types of wood. Physical properties: humidity. Shrinkage.
Specific gravity. Thermal expansion. Electrical and thermal conductivity. Flammability. Mechanical properties of wood: Old approach regarding small test specimens with no flaws. Present approach: Test specimens of structural dimension and with flaws. European standards.
AGGREGATES: Classification. Properties: grading, mix and separation, fineness modulus; particle shape; strength of parent rock, crushing and abrasion strength tests, tests on individual particles and comparative tests; resistance to drying-wetting; resistance to freezing: thermal properties. Cement-aggregate interface. Expansive reactions between cement and aggregate. Pernicious substances in aggregates: Organic; salts; fine, weak, light and unsound particles. Determinations needed for mix-design: specific gravity, humidity and water content. Correction of mixing water.
CERAMICS: clay: composition; classification; properties – plasticity, dry strength, thermal action, porosity, impurities. Production of ceramics: quarry operations, treatment of raw-materials; modelling; drying; burning. Ceramic poducts: general classification; clay materials – bricks, roofing tiles, shackles and clay tiles; glazed earthenware: glazed tiles, lavatories; refractory materials; strength of brick masonry, displacement of clay and glazed tiles.
GLASS: composition; properties; classification; applications.
POLYMERIC MATERIALS: constitutive polymers. Structures; functions; physical, mechanical and hydraulic properties. Testing for property control.
