For several decades, techniques for modifying the surface of steel pipes were practiced with varying results. In addition, these methods did not address either the hydrophobicity of the carbon steel or steel/cement interfacial bond, other than the use of surfactants in spacers and cement slurry. SCIN offers an economical solution to this issue by achieving a superhydrophilic pipe surface that is chemically reactive to Portland cement, allowing an effective bond to cement.
Hi Shady, I was just looking at all of your posts and want to add something to this conversation. I was just reading, dont remember where, that the best mix for in between stones like yours is sand with some portland cement mixed in at a rate of 8 parts sand to one part cement. It will give stability to the shifting that occurs during winter of the stones. It sounded like a good idea to me. I am all for the combining of smaller beds into larger ones too. It saves time mowing between them and looks better too. I am sure you will come up with wonderful plantings but would use hellebores in there. They can take quite a bit of sun ...

From a crisis management perspective, the primary responsibility of the Metropolitan Police was to resolve the crisis, and do so in a way that would minimize the damage to themselves and the government, while maximizing the opportunities that were presented. This means that they were responsible for more than simply catching the Ripper - they were also responsible for reassuring the public, helping to ease public panic, and protecting their reputation. While the Metropolitan Police did as good of a job at trying to capture the Ripper as could be expected of them, given their level of technological and criminological sophistication, they consistently failed to minimize the damage not catching the Ripper had on their organization, and they completely lost control over their crisis communications. The result of their failure to control the crisis manifested itself in many ways. The public lost confidence in the Police. The upper echelons of the police were shaken up, with resignations of many of ...

QUEIROZ, Celso Emanoel de Souza et al. Evaluation of cytotoxicity of two endodontic cements in a macrophage culture. J. Appl. Oral Sci. [online]. 2005, vol.13, n.3, pp.237-242. ISSN 1678-7757. http://dx.doi.org/10.1590/S1678-77572005000300007.. Compared to gutta-percha, the endodontic cements are used in small quantity to seal root canals, but are indispensable to achieve hermetically sealed margins, where its biocompatibility depends on the sum of responses of each cell present in the periapical region. The object of this study was to evaluate the cytotoxicity of two endodontic cements, one based on epoxy resin (Sealer 26) and the other containing zinc oxide eugenol (Endofill) by using cultured peritoneal macrophages from Swiss mice to measure the induced production of nitric oxide. After solidification and pulverization, aliquots of 100ml of suspension containing 18mg/mL of the respective cements were added to 96-well tissue culture plates containing the tissue culture of macrophages at a ...
The Portland Cement Company site is 71 acres of land near 1000 South Redwood Road in Salt Lake City. The site is situated in a mixed commercial and industrial area bordered by agricultural land.. Between 1963 and 1983, approximately 500,000 cubic yards of cement kiln dust (CKD) were collected from the Portland Cement Plant in Salt Lake City and deposited as fill material at the site. CKD contains several heavy metals, including arsenic, lead, chromium, and cadmium.. The Environmental Protection Agency (EPA) placed the site on the Superfund National Priorities List (NPL) in June 1986. Documents: ...
Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) in a GGBS-in-Ca(OH)2 solution (pH > ~12.5) after 10 h, whereas in distilled water (pH = ~11.5) GGBS exhibited only marginal sorption and reduction (20%). Cr reactions with dissolved ions in supernatants derived from GGBS indicated that the anions dissolved from GGBS act as a reducing agent for Cr(VI) in a Ca(OH)2 solution. Soft X-ray absorption microscopy identified a partial reduction of Cr(VI) to Cr(III) on the GGBS surface. The carbonation of pure PC paste substantially increased the amount of dissolved Cr(VI) in a solution phase whereas a 5 wt % replacement of PC with GGBS significantly reduced the amount

Concurrently to research conducted on ordinary Portland cement (PC), new types of binders were developed during the last decades. These are formed by alkali-activation of metakaolin or ground-granulated blast furnace slag (GGBFS) and are named, respectively, geopolymers (GP) or alkali-activated slag (AAS). Four different cementitious materials were synthesised: PC, AAS, GP, and a mix GP-AAS and fully compared about their compositions and (micro)-structures. X-ray diffraction has revealed the presence of semi-crystalline C-S-H gel binding phase in PC while AAS, GP and GP-AAS are nearly amorphous. Progressive structural changes have been observed between the different samples by means of infrared spectroscopy, ...

Xypex is manufactured in the form of a dry powder compound consisting of portland cement, very fine treated silica sand and various active proprietary chemicals. When mixed with water and applied as a cementitious coating, the active chemicals in Xypex cause a catalytic reaction which generates a nonsoluble crystalline formation of dendritic fibers within the pores and capillary tracts of concrete. Thus, the concrete itself becomes permanently sealed against the penetration of water or liquids from any direction. ...
