Test No. 4 "Specific Gravity and Absorption of Fine Aggregate" (ASTM C 127-88) I. Objectives: This test method covers the determin ation of Bulk and Apparent Specific Gravity and Absor ption of fine aggregste. Materials: 1 kg of sand is used using sample splitter. Apparatus: 1. A balance having capacity of 1 kg or more sensitive to 0.1 gm. 2. Pyenometer : A flask or other container into which the fine aggre- gate sample can be introduced. It is usually of 500 cm'capacity. 3. Mold: a metal mold in the form of a frus tum of a cone with dimensions as follows : 37 mm inside dia meter at the top, 90 mm inside diameter at the bottom and 15 mm in height. 4. Tamper: a metal mold in or tamper weighing 340t 15 gm and having a flat circular tamping face 25 mm in diameter. 5. Electrical oven. 6. A container suitable to submerge the sample with water.
