FIELD: transport.
SUBSTANCE: invention relates to anchor for submersing anchoring underwater research hardware at bottom. Proposed anchor consists of flat self-breakable concrete body with central bore to accommodate underwater instruments retention and release. Note here that said body is made from raw stock of the following composition, in wt %: Portland cement - 26.0-56.0, high-alumina cement - 0.6-2.4, semiaquatic gypsum - 3.0-6.0, quartz sand making the rest, water for tempering to solid water ratio - 0.1-0.18. Note here that product of magnitudes of semiaquatic gypsum and high-alumina cement is selected, preferably, equal to 1.8-3.5. Invention is developed in dependent claims.
EFFECT: anchor of nonpolluting materials with self-controlled destruction in sea and sweet water.
