When you look at the walk-behind compactors in your fleet, chances are you don't think of them as precise scientific instruments. Yet, soil compaction is a science and it requires a certain degree of ...

Understanding the dynamics of granular materials—such as sand flowing through an hourglass or salt pouring through a shaker—is a major unsolved problem in physics. A new paper describes a pattern for ...

Johns Hopkins engineers have uncovered new details about how granular materials such as sand and rock behave under extreme impacts—findings that could someday help protect the Earth from dangerous ...

A new and rapid way to pack identical cubes in a dense configuration has been discovered by physicists in Spain and Mexico. Their work offers new insights into granular compaction and could lead to ...

Summary: The main goal of this project is to investigate how the use of compacted granular columns (CGC) may help improve the seismic performance of embankments on potentially liquefiable soils. First ...

Both reversible plates and trench rollers can compact soil in confined spaces. When considering which of these compactors to use, the type of soil and size of the job need to be taken into account.

A Gaza Strip study found that a blend of 95 percent demolition crushed aggregate and 5 percent clay showed the most balanced ...

The authors studied the behavior of anhydrous lactose and the combination of anhydrous lactose and the combination of anhydrous lactose with microcrystalline cellulose on a pilot-scale roller ...

There are significant benefits to dry granulation, in terms of cost-reduction and processing, and it can be used with sensitive materials. However, there is little indication as to which process ...

Several challenges may be presented when processing powder blends: the blend may be prone to segregation, the creation of agglomerates may influence homogeneity, or component powders may poorly flow ...
