Soil Compaction Handbook

Proctor Test. A particular soil needs to have an ideal (or optimum) amount of moisture to achieve maximum density. This is important not only for durability, but will save money because less compaction effort is needed to achieve the desired results. Proctor Test (ASTM D1557-91) The Proctor, or Modified Proctor Test, determines the maximum

A Simple Guide to Concrete Cube Testing

Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.
