| titleOfInvention | A kind of preparation method of PHC pile tube dedicated functionality polycarboxylate water-reducer |
| abstract | The present invention discloses a kind of preparation method of PHC pile tube dedicated functionality polycarboxylate water-reducer, this water reducer occurs free radicals copolymerization reaction to be obtained in aqueous medium by polymeric monomer A, minor comonomer B, minor comonomer C, minor comonomer D under water-soluble redox system effect, and wherein the mol ratio of monomer A, B, C, D is 1:(3～9):(1～3):(1～3).The functional polyalkylene carboxylic acid water reducer advantage of the present invention is：1. the polyether macromonomer of appropriate design can significantly improve the stomatal parameters within maturing and distribution consistency degree, significantly increases the comprcssive strength of concrete；2. it is obviously improved the early hydration of cement, improve the early strength of concrete；3. there is under relatively low volume good dispersion and dispersion holding capacity, significantly increase concrete strength and early strong effect projects；4. fresh concrete service behaviour is good and apparent viscosity is low, is easy to construct. |
