The emulsion stability can be improved by the addition of additional surfactant, and depending on the surfactant type and concentration, the emulsion stability may be controlled to above 300°F (149°C) BHCT. The surfactant system also acts as a dispersant in the cement slurry, resulting in low slurry viscosity.

Slag Cement Association

Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased ...

Measuring and Removing Moisture in Concrete

driven into the surface to get the conduc-tivity reading at the surface (Fig. 2). Although this is a fairly accurate method of measurement for drywall or known species of wood, where the exact makeup of the material is known, poured concrete is not nearly as consistent. Con-crete’s conductivity is affected by voids,

Surface tension

Surface tension is an important factor in the phenomenon of capillarity. Surface tension has the dimension of force per unit length, or of energy per unit area. The two are equivalent, but when referring to energy per unit of area, it is common to use the term surface energy, which is a more general term in the sense that it applies also to solids.

Dispersion of single-walled carbon nanotubes of narrow

The dispersibility and bundle defoliation of single-walled carbon nanotubes (SWNTs) of small diameter (<1 nm) have been evaluated on CoMoCAT samples with narrow distribution of diameters. As previously observed by photoluminescence and Raman spectroscopy, the CoMoCAT sample exhibits a uniquely narrow distribution of (n,m) structures that remains unchanged after different dispersion conditions ...

What is blinding concrete?

Jun 21, 2017 · Blinding concrete is a layer of (usually) lower grade, possibly unreinforced concrete placed on the ground. It serves to isolate the structure and/or users above it from the soil below, and also to provide a stable, potentially flat surface above ...

Characterizing the Distribution of Nonylphenol Ethoxylate

anionic surfactant, nonionic surfactant and 50/50 anionic/ nonionic surfactants mixture were adjusted to between 4 and 5, which is consistent with pH level of latex emulsion. A Zorbax Eclipse XD8-C8, 25 × 4.6 mm × 5 µm, column (Agilent, Fort Worth, TX) was used and the surfactants were eluted with a

Antibacterial Coatings: Challenges, Perspectives, and Opportunities

Antibacterial coatings are rapidly emerging as a primary component of the global mitigation strategy of bacterial pathogens. Thanks to recent concurrent advances in materials science and biotechnology methodologies, and a growing understanding of environmental microbiology, an extensive variety of options are now available to design surfaces with antibacterial properties.

HLB (Hydrophyl Lipophyl Balance) Value : How to

The correct HLB value usually translates to superior stability at a lower use level. For example: our unique formula with a surfactant blend at HLB 11.2 at a 4% use level will most likely give longer stability at elevated temperatures

Surfactant aggregates and their stability in relation to

Surfactant molecules are removed from the surface by adsorption onto or dissolution in the soil. Finely divided hydrophobic silica particles break the foam by adsorbing surfactant molecules from the bubble surface and carrying them into solution. The presence of certain types of soil in a surfactant solution shows decreased foaming due to this ...
