In conjunction with petrographic examinations and other laboratory tests, we also do the following physical testing of construction materials on as-needed basis:

​

1. Compressive strengths, e.g., ASTM C 42 for concrete

2. In situ strength testing by Impact Hammer

3. Cold and Boiling-Water Absorption and Saturation Coefficient of Masonry Units (e.g., ASTM C 67)

4. Cold-Water Absorption of Dimension Stones (ASTM C 97)

5. Density, Absorption, Specific gravity and Volumes of Permeable Voids (ASTM C 642)

6. Length Change Measurements with a Digital Length Comparator (ASTM C 157) to Determine Length Changes Due to Controlled Shrinkage or Expansions

7. Length Change Measurements of Cement-Aggregate Combinations During Accelerated Expansion Tests due to Alkali-Silica Reactions of Mortar Bars (e.g., ASTM C 1260, ASTM C 1567) or Concrete Prisms (ASTM C 1293)

8. Length Change Measurements of Rock Prisms for Alkali-Carbonate Reactions (ASTM C 586)
