Specifying manufactured sands for concrete applications

In concrete pavement, it was found by the CCAA (2012) that the free silica limit used in the selection of natural sand to provide good skid and abrasion resistance to concrete pavement does not necessarily apply to manufactured sands. A sand durability test, based on the Micro-Deval abrasion test method, has been found to be effective in identifying suitable sands (both natural and manufactured sand) that provide good skid and skid after wear to the micro-texture of concrete pavement.

This sand is also called Artificial Sand Or Manufactured Sand or M-Sand.

Concrete Pumping - How to Pump Cement - Concrete Network

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.
