Mix Design and Pumped Concrete - Civil Engineering Portal

Concrete without admixtures and of high cement content, over about 460 kg/m 3 are liable to prove difficult to pump, because of high friction between the concrete and the pipeline. Cement contents below 270 to 320 kg/m 3 depending upon the proportion of the aggregate may also prove difficult to pump because of segregation within the pipe line.

The Disadvantages of Pouring Concrete Over Existing

A well-poured concrete slab with a deep, sturdy foundation can last for 30 to 40 years. Pouring concrete over old concrete instead of directly over a new gravel foundation limits your ability to maximize the slab's lifespan. The condition of the existing slab is the primary factor that determines how long the new concrete will last.

Self-Compacting Concrete Applications and Advantages

Jun 16, 2019 · Self-Compacting Concrete Uses . Self-compacting concrete has been used in bridges and even on pre-cast sections. One of the most remarkable projects built using self-compacting concrete is the Akashi-Kaikyo Suspension Bridge.In this project, the SCC was mixed on-site and pumped through a piping system to the specified point, located 200 meters away.

Underwater Concrete - an overview | ScienceDirect Topics

Graham Tailor, in Advanced Concrete Technology, 2003. 11.3.5 Strength. With a high cement content, strengths of 50 MPa are readily achievable, although designers often feel they have to allow for weak bands in the concrete and assume strengths of around 30 MPa in their designs. As noted above, because underwater concrete is not mechanically compacted and there is an excess of water in the mix

Concrete Pumping - How to Pump Cement - Concrete Network

Line length: Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
