Assessing the Pumpability of Concrete

assessing the pumpability of concrete. This research is done in China, the country with the highest concrete production and placement, to prevent delays from interfering with the high speed development. The final result of this research program should be the development of a testing method to assess the pumpability.

Study on concrete pumpability combining different

The study concentrates on the composition and rheological properties of the lubrication layer forming at the interface to the pipeline wall, since this layer is widely considered crucial for concrete pumpability. For this purpose, the material forming the lubrication layer (LL) is sampled from the various concrete …

Predicting Pumpability and Shootability of Crushed

Nov 14, 2016 · This study aims to estimate the pumpability and shootability of wet-mix shotcrete (WMS) made with crushed aggregates and various admixtures such as silica fume, fly ash, ground granulated blast furnace slag (GGBFS), metakaolin, and steel fiber based on rheological properties. The IBB rheometer was employed as an apparatus to measure the rheological properties of freshly mixed …

Influence of Pumping on Fresh Concrete Properties for SCC

Pumpability of Self Consolidating Concrete Abstract During field trials, involving pumping of self compacting concrete, changes in rheological properties have been observed. In order to predict possible changes, studies were undertaken on self compacting mortar (SCM) where various mixing as well as pumping intensities were applied.
