Bulk density is the weight of soil for a given volume. It is used to measure compaction. In general, the greater the density, the less pore space for water movement, root growth and penetration, an seedling germination. Facts About Bulk Density. Bulk-density depends …

Bulk Density of sand = Mass od sand / volume. Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contain both the sand and the voids between sand particles. The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520-1680 kg/m 3 ...

its bulk density from the following relations. From the Figures 1, 2 and 3 it is observed that the bulk density, packing density are maximum and voids ratio is minimum for 70 % of coarse aggregate (20mm) and 30 % of coarse aggregate (12.5mm) respectively. Fig 1: Maximum bulk density for 20mm and 12.5 mm aggregates

Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.

Bulk Density The cylindrical measure is filled about 1/3 each time with thoroughly mixed aggregate and tamped with 25 strokes by a bullet ended tamping rod, 16 mm diameter and 60 cm long. The net weight of the aggregate in the measure is determined and the bulk density is calculated in kg/litre.
