Laboratory on Materials

Course Units

#	Title	Description	Hours
1	Safety and Health	Marking and instructions. Precautions and means of personal protection. First Aid.	1Χ3=3
2	Measurement devices and methods	Metrology and measurement techniques. Loading and deformation measurement and devices. Calculating and statistical analysis.
3	Aggregates	Grain size analysis, sand density, absorption of coarse aggregates	1Χ3=3
4	Concrete	Concrete mix design, study on concrete’s properties, at fresh (slump, density, entrained air) and hardened (concrete strength) state, calculation of compressive strength.	1Χ3=3
5	Soil	Students are introduced to the particulate nature of soil by handling sand and silt particles and dried out clay minerals. Natural soils are also examined and the methods used to define their grading are discussed. The soils’ ability to resist loads is examined with the aid of simple model tests on disks simulating soil grains. The effect of gravity and water in soil strength is acknowledged through simple experiments, indicating that soil is a very complex material. The students are introduced to soil classification tests by handling a natural clay at its liquid and plastic limit state, and by measuring the density of a sand.	3Χ3=9
6	Steel	Ductile fracture. Stress / strain draft diagram. Determination of yield strength and material characterization based on yield strength. Calculation of Modulus of Elasticity. Calculation of strains (plastic, total).	1Χ3=3
7	Aluminum	Brittle fracture. Stress / strain draft diagram. Calculation of yield strength. Determination of ultimate strength and materials characterization. Calculation of Modulus of Elasticity	1Χ3=3
8	Clay Masonry Units	Methods of testing for clay masonry units. Determination of dimensions, determination of flatness, determination of compressive strength (mean value and standard deviation).	1Χ3=3
9	Asphalt – Asphalt mix	Determination of asphalt softness or hardness and its role in asphalt mix performance. Viscoelastic behavior of asphalt mix	1Χ3=3
