CE 405 - CONSTRUCTION MATERIALS AND TESTING LESSON I.I GENERAL PHYSICAL PROPERTIES OF MATERIALS ENGR. RANDEL LUIS I PANGAN INTENDED LEARNING OUTCOME I. Understanding Material Properties: Students will be able to describe the fundamental mechanical properties of construction materials, such as strength, elasticity, ductility, and hardness. II\. Material Testing Methods: Students will demonstrate knowledge of various testing methods (e.g., tensile, compression, shear, and impact tests) and explain their significance in evaluating material behavior. III\. Stress-Strain Relationships: Students will be able to analyze and interpret stress-strain curves. Identifying key points such as the proportional limit. I.I DENSITY (DRY) - is the dry mass per unit volume of a substance under absolute compact conditions. ![](media/image2.png) 1.2 BULK DENSITY - refers to the mass per unit volume of the substance under conditions that powdery or granular materials are packed. It is the mass of a unit volume of material in the natural state. 1.2 DENSITY INDEX - ![](media/image4.png)the ratio of bulk density and density. It indicates the degree to which the volume of the material is filled with solid matter. 1.4 TRUE OR ABSOLUTE SPECIFIC GRAVITY - if both the permeable voids are excluded for determining the true volume of solids, the specific gravity obtained is called the true or absolute specific gravity. 1.6 POROSITY - ![](media/image6.png)is defined as the ratio of the total pore volume to the apparent volume. 1.7 VOIDS - Empty space in the materials. 1.8 HYGROSCOPICITY - ![](media/image8.png)Ability of the material to absorb water vapor from the air. Moisture content is the percentage of the water contained in a material to its dry mass. 1.9 WATER ABSORPTION - Refers to the percentage of the absorbed water\'s volume to the materials natural volume. When the material absorbs water to saturation.
