1.Tests on natural aggregates
- Aspect and shape of grains
- Void volume
- Grading curve
- Resistance to frost-thaw
- Content of small foreign matters
- Determination of particle density and water absorption
- Humidity
- Clay content
- Coal content
- Humus content
- Determination of loose bulk density and voids
- Dry density and density in natural conditions
- Water absorption and apparent porosity
- Average values b/a and c/a of grains with d min. > 7,1 mm
- Non-uniformity coefficient
- Fines content
- Assessment of fines – Methylene blue test
2.Tests on cement
- Mechanical strength
- Density
- Impermeability degree
- Resisntance to frost-thaw
- Core sampling, examination and compressive strength
