Heavy-weight high-load concrete tubular pile and preparation method therefor
The invention discloses a heavy-weight high-load concrete tubular pile. The heavy-weight high-load concrete tubular pile is prepared from the following raw materials in parts by weight: 1.3-2 parts of polyimide, 10-19 parts of heavy calcium carbonate, 3-7 parts of aluminum dihydrogen phosphate, 0.1-0.2 part of potassium titanate, 1-2 parts of polyvinyl pyrrolidone, 4-6 parts of n-methyl pyrrolidone, 500-640 parts of ordinary Portland cement, 300-400 parts of yellow sand, 200-300 parts of gravels, 7-15 parts of polycarboxylic acid water reducing agent, 16-20 parts of polyethylene wax, 0.1-0.2 part of dibenzoyl 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/used rubber powder and 0.1-0.2 part of polyvinyl alcohol. The heavy-weight high-load concrete tubular pile has the advantages that the content of harmful pores and defects in a concrete structure can be reduced, the alkalinity of hydration products is lowered, and the transformation of low-strength hydration products to high-strength hydration products is prompted.
