A method for synthesizing concrete polycarboxylic acid water-reducing agent at room temperature under non-stirring situation is disclosed, which comprises dissolving reactive materials, initiator, chain transfer agent and promoter into a solvent, reacting on standing at 0-50?; then adding neutralizing agent at the end of reaction. The method makes use of oxidation-reduction system reacting at low temperature, and can adapt to a variety of reactive material monomers. It does not need to control feeding speed or provide extra heating, does not need to stir during the reaction, and remarkably simplifies operation steps in traditional process, which makes it possible to not only produce in large scale, but also produce in small scale in concrete construction site at any moment.
