Unformatted text preview: property may be estimated by breaking a sample of the rock into smaller pieces. . Chemical stability: Resistance to chemical reactions that lead to the deterioration of the materials . 3.2 Rocks Physical properties of rocks (4) Surface Character : Bonding characteristics. Excessively smooth, slick, non-absorbent aggregate surfaces bond poorly with cement. Excessively rough, jagged or absorbent surfaces are undesirable because they resist compaction, placement and require excessive cementing material. Visually inspect the rock surface and feel the surface texture to estimate this property. 3.2 Rocks Physical properties of rocks (5) Lecture outline Chap. 1: Geological Materials and Processes 1.
