Abstract
The invention discloses a concrete anti-cracking waterproof agent which is prepared from, by weight, 100 parts of allophane powder, 30-50 parts of modified wollastonite powder, 10-18 parts of phenolicresin hollow microspheres, 10-20 parts of tricalcium phosphate, 6-8 parts of sodium hexametaphosphate, 10-18 parts of 2-amino-2-methyl-propanol, 3-5 parts of sodium thiocyanate, 8-12 parts of diethanolisopropanolamine and 10-15 parts of pentaerythritol. The invention further discloses a preparation method of the concrete anti-cracking waterproof agent. The concrete anti-cracking waterproof agenthas the advantages that concrete drying shrinkage, cracks and concrete mixture bleeding are reduced, material accumulation effect is improved, and concrete waterproof impervious performance and strength are improved, and service life of concrete is prolonged greatly.
