Stone Compaction: The Ways It'll Impact Your Project

Each type of crushed stone will settle at a different rate and will have a different compaction rate. As a result, various materials will need to be compacted down more heavily than others. Depending on the specific project, you may end up requiring 1/2″-1 1/2″ of extra material in order to achieve the desired overall depth post stone ...

Workability of Concrete by Compaction factor Test

The compacting factor test is designed primarily for use in the laboratory but it can also be used in the field. It is more precise and sensitive than the slump test and is particularly useful for concrete mixes of very low workability and normally used when concrete is to be compacted by vibration. The method applies to plain and air-entrained concrete, made with lightweight, normal weight or ...
