What Is the Difference Between Lean Concrete & Flowable ...

Lean concrete is made with low cementitious material content. This means that it does not have many of the heavy, high-density rock and sand elements that normal concrete has. Instead, it can use a mixture of standard concrete materials, reclaimed and crushed concrete, discarded sand and recycled ash.

Understanding Wet-Mix Shotcrete: Mix Design ...

Batching and mixing a high-quality and pumpable . wet-mix shotcrete is not always a simple task, particularly when high dosages of fibers are used. Using a classic mix design approach for conven-tional concrete may result in non-pumpable or difficult to pump concretes. Adding fibers to ordinary wet-mix shotcrete can produce similar effects.

Pumping of Concrete - The Concrete Portal

Water is the only pumpable component in the concrete, and transmits the pressure on to the other components Two types of blockage to efficient pumping could occur: (1) Water can escape from the mixture if the voids are not small enough; this implies that closely packed fines would be needed in the mixture to avoid any segregation.
