Slag concrete pipe pile and preparation method therefor
The present invention discloses a slag concrete pipe pile. The slag concrete pipe pile consists of the following raw materials in parts by weight: 1-2 parts of aluminium sulfate, 30-40 parts of slag, 4-6 parts of n-methylpyrrolidone, 500-640 parts of ordinary portland cement, 300-400 parts of yellow sand, 200-300 parts of crushed stones, 7-14 parts of a polycarboxylate superplasticizer, 16-20 parts of polyethylene wax, 0.1-0.2 parts of dibenzoyl peroxide, 5-6 parts of maleic anhydride, 2-3 parts of polyethylene glycol monomethyl ether, 0.9-2 parts of s p-80, 50-70 parts of waste rubber powder, 0.1-0.2 parts of triethylamine, 0.1-0.3 parts of glycerol triacetate, 0.6-1 parts of potassium bisulfate, and 3-4 parts of ammonium polyphosphate. According to the present invention, harmful holes and the content of defects in a concrete construction can be reduced, alkaline of hydration products can be reduced, and conversion of low strength hydration products to high strength hydration products is promoted.
