Comparative Study of Soil Grouting with Cement Slurry and Cement-Sodium Silicate Slurry

Mixing in the downward displacement of a turbulent wash by a laminar spacer or cement slurry

When drilling an oil well, the well is lined by sinking a steel casing, or liner, into the drilling mud (see Figure 1). The inside of the liner forms a central pipe, and leaves an annular gap between the outside of the liner and the surrounding rock. The inside and outside of the liner are initially filled with drilling mud, which is displaced by pumping a sequence of fluids down inside the lin...

Redistribution of slurry components as influenced by injection method, soil, and slurry properties.

The distribution of moisture, degradable C, and N after direct injection of slurry can affect the turnover and plant availability of slurry N. This study examined effects of injection method, soil conditions, and slurry properties on the infiltration of several slurry components under practical conditions. The water retention capacity of 22 pig and cattle slurries was quantified by dialysis at ...

Long-term effect on the solidified degraded cellulose-based waste slurry in cement matrix

The long-term effects on solidification/stabilization (s/s) of the secondary wastes, resulting from the oxidative degradation of some solid cellulosic-based wastes, in Portland Cement (CEM I) have been investigated by X-ray diffraction (X-RD) and Fourier transform infrared spectroscopy (FT-IR) techniques. The effect of seven years leaching of the cemented waste forms obtained was carried out to...

Comparative Testing of Pipeline Slurry Monitors

Premixed calcium silicate cement for endodontic applications

Calcium silicate-based materials (also called MTA) are increasingly being used in endodontic applications. However, the handling properties of MTA are not optimal when it comes to injectability and cohesion. Premixing the cements using glycerol avoids these issues. However, there is a lack of data on the effect of common cement variables on important properties of premixed cements for endodonti...
