Analysis of shear rate inside a concrete truck mixer - 百度学术

Concrete mixing truck as a rheometer - ScienceDirect

1/1/2020 · For the current analysis, it is important to divide the drum's internal volume between the atmospheric air and the fresh concrete, which is done within the framework of Volume of Fluid (VOF) . The volume fraction of fresh concrete within each computational cell is represented with α 1, while the volume fraction of atmospheric air is represented with α 2 .

Self Compacting Concrete

The entire concrete from the mixer truck is passed through this apparatus, which consists of a box with openings (with reinforcing bars as obstacles) on the sides. If the concrete flows through the apparatus, it is considered as self-compactable for the structure.

Effects of metakaolin on properties and microstructure of …

20/2/2020 · The formal shear is divided into three parts, which are the rising stage of shear rate, the constant stage of shear rate and the falling stage of shear rate. The maximum shear rate was 200 s −1 . First, the shear rate increased linearly from 0 s −1 to 200 s −1 within 60 s, then the shear rate kept constant for 30 s, and finally reduced linearly from 200 s −1 to 0 s −1 within 60 s.
