• Blended cements may be used in concrete construction when specific properties or costs are required. ... Blended hydraulic cements are produced by intimately and uniformly blending two or more types of fine materials. ...
• Type V cement, like other portland cements, is not resistant to acids and other highly corrosive substances. Portland Cement Type IP & P    Portland-pozzolan cements are designated as Type IP or Type P. ... These cements are manufactured by blending portland cement and a pozzolan. The pozzolan content of these cements is between 15% and 40% by weight. ... In producing these cements, granulated blast-furnace slag of selected quality is either interground with portland cement clinker, separately ground and blended with portland cement or produced with a combination of intergrinding and blending. ... Expansive Cements    Expansive cement is a hydraulic cement that expands slightly during the early hardening period after setting. ... Oil-Well Cements    Oil-well cements, used for sealing oil wells, are usually made from portland cement clinker or from blended hydraulic cements. ... The American Petroleum Institute Specifications for Materials and Testing for Well Cements (API Specification 10) includes requirements for nine classes of well cements (classes A through H and J). ... Expansive cements have also performed adequately as well cements.   Waterproofed Cements    Waterproofed portland cement is usually made by adding a small amount of water-repellent additive such as stearate (sodium, aluminum, or other) to portland cement. ...

• The Use of Resin Cements in Restorative Dentistry to Overcome Retention Problems.
• Mots clés MeSH : crowns; dental prosthesis retention; resin cements .
• Resin cements are gaining popularity in the dental profession for a number of reasons. The vast majority of non-metallic restorations, which are also utilized more at the present time than before, can be cemented only with resin cements. ... Resin cements are also the only cement material that can be used for cementation of resin-bonded fixed partial dentures. ...
• Typically, resin cements are used in conjunction with enamel and dentin bonding agents and, as a result, are capable of micro-mechanical attachment to both structures through the bonding agent. ... Some resin cements are formulated in such a way that they possess an additional chemical agent to enable them to bond chemically to cast restorations made of non-precious metal alloys. Unlike resin cements, non-polymeric cements, such as zinc phosphate cement, generally cannot bond to either the tooth structure or the fitted surface of the restoration. One exception is glass ionomer cement, which can bond chemically to both dentin and enamel; however, the strength of the bond is far less than what can be achieved with resin cements. ...
• Another use of resin cements that has evolved and been adopted by dentists is the cementation of posts, both metallic and non-metallic. One study recommended the use of resin cements with dentin bonding agents when the length of the channel hole is less than ideal or when the hole is not rounded. ...
• 2 This implies that bonded resin cements can be useful as alternative cement material in clinical situations where retention of crowns or fixed partial dentures is compromised. ...
• The following selected cases illustrate how resin cements and dentin bonding agents can be used to overcome post- treat ment retention problems. ...
• It must be stressed that when the basic principles of retention, angle of convergence and height are followed accurately, non-polymeric cements have always worked well without the need for added retention through bonding. ...
• Unlike non-polymeric cements, resin cements are typically expensive, and some products have a shorter shelf life. Some commercially available resin cements are more technique-sensitive than others, and in inexperienced hands their use can lead to undesirable results. ...
