Concrete super-retarding agent
The invention discloses a concrete super-retarding agent. The concrete super-retarding agent comprises components in parts by weight as follows: 15-20 parts of EDTMPA (ethylenediamine tetramethylenephosphonic acid), 10-15 parts of ATMP (amino trimethylene phosphonic acid), 15-20 parts of HPMC (hydroxyl propyl methyl cellulose), 10-15 parts of white sugar and 30-50 parts of water. The concrete super-retarding agent has the advantages that the mixing amount is only 0.3%-0.5% of the mass of a cementing material, but the retarding time can be prolonged to 80-100 h, the 28 d setting time is not shortened, but the later strength of concrete still reaches the standard, and compared with an ordinary retarding agent, the concrete super-retarding agent is low in product cost and realizes both economic and technical indicators.
