ASTM International Show all Oven-Dry (OD): The mass of the aggregate after all moisture has been removed. Saturated-Surface-Dry (SSD): The state where the internal pores of the aggregate are full of water, but the surface is dry. This is the most common state used for concrete mix calculations. Apparent Density: This focuses only on the solid portion of the aggregate, ignoring the water-permeable pores within the particles. The Lab Process: Achieving the "Slump" Testing for ASTM C128 is a meticulous two-day process: Soaking: The sand sample is first dried in an oven and then soaked in water for roughly 24 hours to fill its pores. Drying to SSD: The most delicate step involves drying the wet sand until it reaches the SSD condition. Technicians use the astm c128 12
