Rosin-efficient water-reducing concrete pile, and preparation method therefor
The present invention discloses a rosin-efficient water-reducing concrete pile. The pile consists of the following materials in parts by weight: 0.2-0.3 parts of rosin, 4-6 parts of n- methylpyrrolidone, 0.1-0.2 parts of potassium fulvic acid, 500-640 parts of ordinary Portland cement, 300-400 parts of yellow sand, 200-300 parts of crushed stone, 7-14 parts of a polycarboxylate superplasticizer, 16-20 parts of polyethylene wax, 0.1-0.2 parts of benzoyl peroxide, 5-6 parts of maleic anhydride, 2-3 parts of polyethylene glycol monomethyl ether, 0.7-2 parts of sp-80, 50-70 parts of waste rubber powder, 0.1-0.2 parts of triethylamine, 1-1.5 parts of sodium polyacrylate, and 3-4 parts of tetraethyl orthosilicate. The invention can reduce the quantity of harmful holes and defects in a concrete structure, lower the alkalinity of hydration products, and facilitate conversion from a hydration product of low strength to a hydration product of high strength.
