Joints sealant

A sealant is a material that is installed into a gap or joint to prevent water, wind, dirt, or other contaminants from passing through the joint or gap. This joint or gap may be a fixed joint, but is often an expansion joint which may also be called a working joint. Sealants, which can also be defined by how they are tested, are rated by their ability to stretch, twist, bend, and be compressed while maintaining their bulk properties so that they do not tear apart under stress. A most important rating of a sealant in many applications is the movement ability of the sealant. The adhesion required of a sealant is simply the strength to hold the sealant in position as it is stressed and strained. [Pg.308]

Crack and joint sealants Seal coats Interlayers... [Pg.47]

Crack and joint sealants are applied only on cracks and joints. Seal coats include hot asphalt-rubber sprayed on the surface followed by precoated aggregate. Interlayers are the application of seal coats followed by either a standard overlay or an asphaltic-rubber overlay. Asphalt-rubber, when blended with an aggregate hot mix at about 9 to 10 percent by weight, serves as a binder in the thin overlay applied to the road surface. The hot mix binder holds the greatest potential for using large quantities of scrap rubber because of the thickness and quantity of the overlay. [Pg.47]

The selection of an alloy for a specific application is based on the cost and the corrosion resistance of the alloy in the environment of interest. It is also possible to subject the chosen alloy to a process by which the corrosion resistance of the selected material can be improved within the acceptable limits. Some of the corrosion prevention and protection strategies with respect to the aluminum-based alloys are (i) design (ii) alloy selection and joint sealants (iii) aluminum thermal spraying anodic coatings (iv) inhibitors (v) conversion and organic coatings and (vi) cathodic protection.

This property is useful in the case of joint sealants where a movement accommodation factor is the main concern. Elongations of 100% are acceptable. However, it is possible to formulate polysulphides with ultimate elongations in excess of 1000%. [Pg.165]

Silylated urethane polymers allow formulators to produce fast-cure construction joint sealants with superior performance properties. The sealant is composed of silylated urethane polymer, plasticiser (e.g. diisodecyl phthalate), fillers (calcium carbonates), fumed silica, adhesion promoter, dehydrating agent, and catalyst (dibutyltin dilaurate). [Pg.211]

A model sealant is reported to exhibit high elongation and good tensile and tear strength. The sealant finds suitability as a low-to-medium-modulus construction joint sealant. [Pg.211]

If "acid brick" is to be used, the glass-reinforced asphalt membrane is now applied in the usual manner, and the brick laid over it, expansion joints carefully laid out and placed on the usual centers. If a monolithic, whether a %" topping or a polymer concrete, is to be applied, polyethylene separator bars should be set above the cracks around the periphery of every sheet, the monolithic placed, the bars removed, and the cavities thus formed filled with expansion joint sealant. If this is not done, you can be certain that, sooner or later, the monolithic will develop cracks at these points, telegraphing through the surface the pattern of the plywood sheets below it. [Pg.109]

In 1994, 70 tons of SCCPs were used in Switzerland, and it is estimated that uses have reduced by 80%. The most widespread use of SCCPs in Switzerland was in joint sealants. In Germany, the most important uses (74% of the total) of SCCPs were banned by the EU directive 2002/45/EC. SCCPs have been used as a polychlorinated biphenyl (PCB) substitute in gaskets (e.g. splices, in buildings), and this may be a source when buildings are renovated. Brazil indicates that 300 tons per year is used in Brazil for the purposes of flame retardant in rubber, car carpet and accessories. Use of SCCPs in Austraha decreased by 80% between 1998/2000 and 2002 to approximately 25 tons per year of SCCPs in the metalworking industry [16]. In the Republic of Korea and in 2006, SCCPs were mainly used in lubricant and additive agents. The release pattern and quantitative data are not available. Also, the Republic of Mauritius reported that it does use SCCPs [17]. [Pg.9]
