A diaphragm in the plug body ruptures to allow the cement slurry to pass through after the plug reaches the landing collar.

Without a float collar or float shoe, the cement slurry placed in the annulus could U-tube, or reverse flow back into the casing.

Originally granular quicklime was used as binder to stabilize the underlying soil, but soon better results were obtained using cement slurry and cement mortar.

Geopolymer cement is an alternative to ordinary Portland cement and is used to produce Geopolymer concrete by adding regular aggregates to a geopolymer cement slurry.

Ngi Hla Nge's team replaced rusted wrought iron with stainless steel, poured cement slurry to fill cracks and applied a new plaster outer coating that he contends is as strong as concrete.
16.
As plain burlap sandbags deteriorate fairly quickly, sandbag structures meant to remain in place for a long time may be painted with a portland cement slurry to reduce the effects of rot and abrasion.
17.
Cement plugs land on it during the primary cementing operation, thus retaining inside the casing a small portion of the cement slurry that may have become contaminated as the top plug scrapes the inside of the casing.

The NRB features state of the art labs that allow students to work with industry standard and specialty equipment, including a Fracture Conductivity Measurement System, a Vertical Flow Loop, a Cement Slurry Property Testing Lab, and Fracture Stimulation Equipment.
19.
Even if a drilling rig is on location, pumping operations usually are done by a service company's cementing unit that can easily mix small batches of cement slurry, measure displacement volume accurately to spot the slurry on bottom, then pump at very low rates and high pressures during the squeeze itself, and finally measure volumes accurately again when reversing out any excess slurry.
