How to Calculate the Soil Compaction Factor | Hunker

Whether it's an underground pipe, a sidewalk, a home, or a skyscraper, it all depends upon the soil being stable, and not moving due to water or further compression. Various machines compress soil, but the key to using them is knowing how far the compaction still has to go, and when the proper target compaction …

Types of concrete - Wikipedia

During the 1980s, Okamura and his Ph.D. student Kazamasa Ozawa at the University of Tokyo developed self-compacting concrete (SCC) which was cohesive, but flowable and took the shape of the formwork without use of any mechanical compaction. SCC is known as self-consolidating concrete in the United States. SCC is characterized by the following:
