We put on another layer of clothes, slipped spikes onto our boots, and crossed the bowl to its gentler southern side.
The existing methods to measure the rheological properties of slip layer (or called lubricating layer) are first introduced.
Small dots of paraffin served as spacers between the cell layer of the cover slip and the bottom of the 12-well-plate.
Another important area is concerning the procurement of slip layer in long distance pumping.
The yield stress of the concrete and that of slip layer contrarily decreased as the maximum coarse aggregate size increased.
Quantitative evaluations on the long-distance pumping performance or examinations on the loss of slip layer have not yet been conducted.
Second, based on the rheological properties of slip layer and parent concrete, models to predict concrete pumping (flow rate, pumping pressure, and pumpable distance) are explained.
Loss of slip layer is also possible because the rheological properties of concrete change during the pumping (Kwon et al. 2013) and the pumping pressure increases for the long-distance pumping.
For a double bonus, put on a thick layer of lotion before slipping your hands into your gloves; the gloves will trap the moisture and cause it to absorb into your nails and skin faster than usual.
This tribometer was used to assess the rheological properties of the slip layer of highly-workable concrete and SCC (self-consolidating concrete).
