nineteenth century, but due to the beneficial effects of mineral admixtures, such as pulverised fuel ash, ground granulated blastfurnace slag and microsilica, modern cements now contain one of these materials, in addition to small quantities of other types of fine powder used as filler material....
cement was found by only varying the relative proportion of the oxide composition.As time advances, new materials like additives to the clinker at the time of grinding, use of new raw materials resulted in production of new variety of cement.The various types of cements as per Indian Standards...
The results of this investigation indicate the reliability of LIBS to characterize different cement samples and to assess the chloride content in these cements.doi:10.1080/00387010902827668Gondal, MAYamani, ZHHussain, TAl-Amoudi, OSBSpectroscopy Letters...
The results showed that the polycarboxylate cement had a tensile bond strength to smooth, untreated dentin of approximately 4 MN/m2. The zinc phosphate and EBA cements had a bond strength of 0,6 MN/m2 and the composite resin cement had no measurable bond to untreated dentin. All dentin ...
DENTAL cementsDENTAL materialsAim: In an effort to control postoperative sensitivity, dentin sealers are being applied following crown preparations, with little knowledge of how crown retention might be affected. A previous study demonstrated no adverse effect when using...
Watch out: do not mix types of cements (glues) used with plastic water or drain piping with conduit cement. Conduit cement is not suitable for piping and fittings subjected to pressure.Use proper fittings to join and terminate rigid plastic conduit tubing, and protect it from damage too....
Studies of the natural γ-emitting radionuclides in different types of cements manufactured by different companies in Egypt (e.g. Iron (HI), Karnak (HK), and Super fine (HSu) products from Helwan Ltd.) have been done to determine their natural levels of radioactivity using a high-purity ger...
[10,23,32,35,55,56]. Few researchers conducted their studies using ultra-rapid hardening cement like early strength type cement, retarding strength type cement (with the addition of gypsum) and inferred that these type of cements help in reducing the cracks and shrinkage of the grouting ...

Cement-type artificial stone is an artificial stone made of various cements as cementing materials, sand and natural gravel as coarse and fine aggregates, after preparation, mixing, pressure steaming, polishing and polishing. During the preparation process, coloring materials can be mixed to make col...
