Background
The phenomenon of gas existing in liquid is called bubble, the bubble forming phenomenon can be encountered in many processes in nature, and bubbles with different sizes and shapes can be formed when the gas is subjected to the action of shearing force in the liquid. The micro-nano bubbles refer to bubbles with diameters ranging from about several micrometers to several nanometers when the bubbles are generated, are between the micrometer bubbles and the nanometer bubbles, and have physical and chemical characteristics which are not possessed by bubbles generated by a conventional aerator disc. The micro-nano bubble water can improve the current situation of concrete segregation and bleeding in the concrete preparation process; under the condition of ensuring the same working condition, the dosage of the admixture can be effectively reduced; the fluctuation of the workability caused by the unstable quality of the machine-made sand can be reduced; meanwhile, the strength of the concrete can be improved.
