Learning outcomes
The course aims to provide the fundamentals of chemistry and chemical-physics useful for the comprehension of materials structure-activity relationship. It also discusses on the materials of specific interest to the Master of Science in Civil Engineering and Architecture.
Course contents
Hints to chemical formulae and to chemical reactions Qualitative and Quantitative aspects of the chemical formulae. Atomic number and mass number. Isotopes. Chemical Reactions: types and stoichiometry Bond Theory Electronic structure of the chemical elements. Periodic properties of the chemical elements. Ionic bond, pure covalent and polarized-covalent bond. Coordination bond. Metallic bond. Lewis Structures. Molecular Geometries. Molecular Interactions: hydrogen bond, Van der Waals interactions. Ionic and covalent valences of elements of s, p block and first transition row. Oxides, hydrides, anions and cations, salts.Thermodynamics, Kinetics and Chemical equilibrium Thermodynamic Functions: internal energy, enthalpy, entropy. Standard formation enthalpy of the chemical commpounds. Reaction Enthalpies and Hess law. The Gibbs reaction isotherm: the chemical equilibrium. Equilibrium constant, temperature and pressure effect. Electrochemistry. Electrolysis and Corrosion.Solutions The measuring units of concentration: molarity, molality, w/w and w/v percent. Solubility equilibrium (solubility product). Acid-base equilibrium, definition of pH, pH of strong and weak acids and basis. States of Matter Solid state: crystalline systems, Bravais’ lattices, compact structures, reference structures for ionic salts. Covalent (diamonds, graphite, silicon, quartz), metallic and molecular crystals. Liquid state: surface tension, adhesion and cohesion forces, wettability, vapor tension.Phase Equilibria Phase state diagram of water. Thermal analysis of alloys. Eutectic diagrams and diagrams with total and partial solubility in the solid phase.Materials Polymeric materials and structure/property relationship. Metals and ferrous alloys: steel, cast iron, the Fe/C diagram. Thermal treatments. Ceramic materials. Building materials: lime, hydraulic lime, plaster, cements. Wood and derivatives.
