2. Self-consolidating concrete - Wikipedia

   en.wikipedia.org/wiki/Self-consolidating_concrete

   Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).

   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:

4. Engineered cementitious composite - Wikipedia

   For instance, a self-compacting material would be able to fill a mold containing elaborate pre-positioned steel reinforcement without the need of vibration or shaking to ensure even distribution. Self-compacting ECC was developed through the use of chemical admixtures to decrease viscosity and through controlling particle interactions with mix ...

5. Superplasticizer - Wikipedia

   en.wikipedia.org/wiki/Superplasticizer

   Superplasticizers (SPs), also known as high range water reducers, are additives used for making high-strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

   The largest P1 can print objects up to 16m x 9m x 2.5m. [34] Total Custom concrete 3D printer developed by Rudenko is a concrete deposition technology mounted in a gantry configuration, the system has a similar output to Winsun and other concrete 3D printing technologies, however it uses a lightweight truss type gantry.

   The rebuilt upper reservoir of the Taum Sauk plant, nearing completion in this photo, is the largest RCC dam in North America. [1]Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement.

   Small, handheld tampers are used to compress ground coffee into a puck to prepare espresso.; A fancy coffee tamper. Manual or powered tampers compact gravel before laying a concrete or brick patio or walkway so that the underlying gravel layer does not settle over time, or compress the fill in a utility trench as seen in the illustration.
