The following are several common methods for preparing anti-segregation agents for concrete:
-
Acrylic emulsion method: After mixing acrylic acid, methyl methacrylate, cetyltrimethylammonium bromide and other materials, add emulsifiers, surfactants and other additives to make an acrylic emulsion for concrete Resistant to segregation.
Acid-base neutralization method: neutralize certain compounds containing acidic groups, such as urea-formaldehyde resin, etc., with alkaline compounds, such as sodium hydroxide, etc. and react to produce a chemical agent with anti-segregation effect.
Portland cement method: Portland cement is mixed with other chemicals to make concrete anti-segregation agent. Portland cement can react with free calcium oxide in concrete to form solid cement, thereby reducing the segregation of concrete.
Calcium-based anti-segregation agent method: By adding a certain amount of calcium-based anti-segregation agent, such as sulfoaluminate, etc. to the concrete, the voids in the cement paste can be reduced , improve the density of concrete, thereby achieving the effect of resisting segregation.
