Rebound Hammer Test on Concrete

Rebound Hammer Test on Concrete

The test specimens should be as large a mass as possible in order to minimize the size effect on the test result of a full scale structure. 150mm cube specimens are preferred for calibrating rebound hammers of lower impact energy (), whereas for rebound hammers of higher impact energy, for example 30 Nm, the test cubes should not be smaller than 300mm.

Rvalue (soils)

Rvalue (soils)

The RValue test measures the response of a compacted sample of soil or aggregate to a vertically applied pressure under specific conditions. This test is used by Caltrans for pavement design, replacing the California bearing ratio test. Many other agencies have adopted the California pavement design method, and specify RValue testing for subgrade soils and road aggregates.

 · If a statement is like: A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. For testing, British Standard (BS 812) has specified the degree of compaction. These are; Loose ( Uncompacted) Compacted; The test will be carried out by using metal cylinder having prescribed depth and diameter and the bulk density is to be ...

More specifically, aggregate is used to describe the structure formed by the cohesion of colloidal particles. Aggregation is the process or the result of the formation of aggregates. When a sol is colloidally unstable ( the rate of aggregation is not negligible) the formation of aggregates is called coagulation or flocculation.
