The most common materials containing asbestos are stucco, tar paper (roofing felt), roll roofing, plastic roof cement (at joints between roofing and other materials and at penetrations), window putty, asbestos-cement siding, asbestos cement flues, pipes, and roofing, drywall joint compound, sheet vinyl flooring, acoustic ceiling texture, vinyl floor tile, floor tile mastic, mirror mastic, HVAC ducts made of corrugated asbestos covered with aluminum on the inside and outside, corrugated insulation for use over metal ducts, pipe insulation, boiler and tank insulation, structural steel fireproofing, light fixture insulation, gaskets, paper duct insulation, and appliance wiring.

Abatement can be as simple as removing concrete asbestos siding, or a huge pain in the *** if you are dealing with asbestos floor tile and mastic.  

@Nathan ZhivalyukIt looks like it could be asbestos insulation - or it could be fibreglass insulation with mastic (which may or may not contain asbestos itself) - I cannot tell from the photo.If you can find a knowledgable (& perhaps a little gray) contractor (HVAC, plumbing, etc) in your area, they should be able to tell w/o causing any disturbance.Pipe insulation is considered friable (Category I), but is also relatively easy to remove and abatement is not terribly expensive.  

You want to ensure that the adhesive wasn't black mastic glue.

I'm wholesaling a deal in Mastic, NY.

Never use "premixed mortar," which is really just adhesive mastic with sand in it.

The most common materials which contain asbestos are drywall joint compound, sheet vinyl flooring (not linoleum), vinyl floor tile, floor tile, mirror, and other mastics, window putty, pipe, tank, and boiler insulation, HVAC duct insulation, asbestos-cement flues, asbestos-cement shingles (roof or wall), acoustic ceiling texture, stucco, roofing materials, and even sound insulation on steel sink bottoms.
