Coatings concrete

All reported incidents. Includes all reports of anchor, cable or trawl contact and also severe concrete coating damage. 

The material once installed is then covered with a concrete coating, the minimum thickness of cover above the anode mesh is quoted as 10 mm, but 15 mm is preferred. 

Some use has been made in the water industry of loose envelopes of polyethylene sheeting and with the increasing lengths of submarine pipeline requiring heavy concrete coatings for reducing buoyancy, the use of a heavily filled bituminous coating is projected. 

Example of a Starting Formulation for a UV Curable Concrete Coating... 

In units of BTU per hour per square foot of surface per °F mean temperature difference. U-values for steel pipe are quite high, but the addition of a thick concrete coating plus the effect of burying the pipe under several feet of bottom sediments could result in a very low U-value. Experimental data under controlled conditions is difficult If not impossible to obtain, but we can calculate U-values as low as 0.15. In actual practice we may experience average U-values as high as 1.0 to 2.0, particularly if some 1 sections of the pipeline do not remain completely buried. 

Concrete Coatings. The durability, weatherability, and chemical resistance of composites match up well with the required properties of protective coatings for concrete and other rigid materials. A typical application is the protection of concrete structures from the acid solutions used in metal ore leaching plants (9). In one such application, sulfur composite was applied to two leaching vats of a new experimental copper ore leaching facility (Figure 8).

Technologies offered by unsaturated polyesters to the construction industry are directed at specific areas such as anchoring grouts, resin mortars and concretes, coatings and lighting sealants. The properties that make unsaturated polyesters more useful for construction are (Boeing, 1964 Demmler and Schlag, 1971 Manson, 1985) ... 

According to the theory of V. Solomatov and V. Seljaev [8], shrinkage stresses in a concrete coating create the compressive stresses ocon in contact layer of a concrete substratum. Therefore, the value of the moment MCTack carried by a section before crack formation in a substratum is increased and it is possible to determine a formula...

Floating platforms are generally protected by CP (sacrificial anodes or impressed current) combined with a high-quality paint system. Pipelines with an organic coating and an external concrete coating are also protected by sacrificial anodes. 

Figure 10.17 shows various arrangements for fixing saerifieial anodes on tubular struetures. Submarine pipelines are usually proteeted by bracelet anodes encompassing the pipe and flush wifli the outer concrete coating. Sacrificial anodes on ship hulls are commoidy flush-mounted and welded directly to the hull.
