2021-4-23  2. Coarse Aggregate: This types of Aggregates whose particles are larger than 4.75 mm are termed as coarse aggregate. For RCC work, generally 20 mm aggregate is used. aggregate types based on its unit weight: 1. Lightweight aggregate: Its Unit weight up to 121 kN/m3.

Standard Weights for Crushed Rock Per Meter Hunker

The weight of crushed rock will vary greatly depending on the type of the stone and the size and uniformity of the crush. The smaller the crush size, the heavier the load. Natural rocks, 12 to 24 inches, which are commonly used in landscaping, are approximately 1.18 tons per cubic meter. Two-inch to 12-inch over-sized rocks

METHOD OF TEST FOR UNIT WEIGHT OF AGGREGATE

2019-11-27  2.Calculate the unit weight of the aggregate from the following formula: Unit weight per cubic foot = FA.
