"Glass cylinder with one flat end."
A: "This is a glass tube filled with concrete epoxy. It goes in the hole in the concrete before the anchor bolt. When the bolt is inserted it breaks the glass and the epoxy mixes with oxygen and solidifies, thus holding the bolt in place. I don’t think they are very popular since epoxy comes in caulking tubes these days."

#19,,, Firstly the epoxy resin mixes with the catalyst contained inside the smaller vial within the ampule and forms an epoxy, this spreads around the rebar or bolt and is mixed along with the grit also encased. bond is stronger than the brick or rock it is inserted in,

#16 It's a nesting house for Carpenter Bees. They're great little pollinators! They bore into wood, usually dead wood instead of live trees.
