Chemical and physical admixtures were properly introduced for the regulation of the rheological property and hardening speed of the fresh cement mixture slurry as well as the physical properties of the hardened foamed concrete.
The results showed that materials composition have significant effects on the water absorbing capacity, compressive strength and flexural strength of hardened water-retentive slurry, as well as the workability of fresh WRS.
Based on balances of kinetic energy, two theoretical equations were derived giving the critical impeller speed as a function of physical properties of the mixed slurry as well as of several selected geometrical parameters of the mixing device.
In contrast to that, a Danish one-year study on two field sites with "structured, loamy soil" [13] found E1 and E2 in the drainage pipes within 14 30 days after application of pig manure slurry as well as continued leaching in high concentrations after 3 months.
The method to synthesize HAp-Gel slurry was well described in previous studies [ 11].
Fermentation profiles of ethanol production and glucose consumption were obtained from the slurry, as well as profiles of cultures grown on the reference fermentation test using medium containing the same concentration of glucose.
The results showed that the hyperbolic model predicated the shear thinning relationship for the smart cement slurries very well.
The sorption isotherms of CO2 in these slurries, as well as in aqueous solution of mIm, were measured in the temperature range from 293.15 to 313.15 K.
The dispersion properties of carbon black (CB) slurries as well as the accompanying electrochemical properties of Li(Ni1/3Co1/3Mn1/3 O2 (NCM) electrodes were investigated by controlling the amine value of polyurethane-based dispersants.
An axisymmetric finite element model was then developed and used to conduct a parametric study to investigate the thermomechanical response of oil wells with cement sheaths made of the various cement slurries, as well as the influence of applied temperature gradients, heating durations and formation stiffness.
This type of ready-to-use cement can be of particular interest in adhesive applications requiring enhanced bond to substrates (i.e., tile adhesives, patching mortars, waterproofing slurries) as well as repair and injection works necessitating improved durability and adhesion to embedded steel bars.
