Example Embodiment
[0009] Example 1
[0010] The present invention is a new type of concrete modifier, which is made of the following raw materials in parts by weight:
[0011] 4.8 parts of butadiene, 2.6 parts of ethylene dichloride, 1.8 parts of polyacrylonitrile, 7 parts of deionized water, 1.4 parts of propyl paraben, 2.8 parts of polyamide-chloromethyl propylene oxide resin and cellulose acetate butyrate Vegetarian 1.3 servings.
Example Embodiment
[0012] Example 2
[0013] The present invention is a new type of concrete modifier, which is made of the following raw materials in parts by weight:
[0014] 2.5 parts of butadiene, 1.2 parts of ethylene dichloride, 1.3 parts of polyacrylonitrile, 5 parts of deionized water, 0.8 parts of propyl paraben, 2.5 parts of polyamide-chloromethyl propylene oxide resin and cellulose acetate butyrate Vegetarian 0.8 servings.
Example Embodiment
[0015] Example 3
[0016] The present invention is a new type of concrete modifier, which is made of the following raw materials in parts by weight:
[0017] 6 parts of butadiene, 3.5 parts of ethylene dichloride, 2.6 parts of polyacrylonitrile, 10 parts of deionized water, 2.2 parts of propyl paraben, 3.6 parts of polyamide-chloromethyl propylene oxide resin and cellulose acetate butyrate 1.8 servings.
[0018] Compared with the existing modifier, the water reduction rate of the present invention is greater than 6%, and the segregation is significantly reduced; the pumpability and workability of the concrete are significantly improved; when the air content is less than 6%, the flexural strength of the concrete can be increased by 10 -30%; frost resistance increased by more than 10 times; salt frost erosion resistance increased by more than 5 times; other durability such as salt crystallization pressure damage, alkali aggregate reaction damage, etc. are also significantly improved...
