Acid-corrosion-resistant concrete pipe pile and preparation method thereof
The invention provides an acid-corrosion-resistant concrete pipe pile and a preparation method thereof. The acid-corrosion-resistant concrete pipe pile comprises the following components in parts by weight: 280-380 parts of cement, 130-160 parts of quartz ultrafine powder, 980-1230 parts of granite macadam, 520-780 parts of quartz sand, 110-160 parts of water, 10-22 parts of a water reducing agent, 28-48 parts of potash water glass and 3-9.6 parts of aluminum tripolyphosphate. The SiO2 content of the quartz ultrafine powder is greater than or equal to 90%, and the specific surface area is greater than or equal to 500m < 2 >/kg. According to the formula component concrete, the corrosion resistance of the pipe pile is improved, corrosion of an acid medium to pile body concrete is avoided, steel bars in the pipe pile can be protected against corrosion, the structural strength of the pipe pile is improved and the service life is prolonged.
本发明提供一种抗酸性腐蚀混凝土管桩及其制备方法，包括如下重量份数的组分：水泥280～380份、石英超细粉130～160份、花岗岩碎石980～1230份、石英砂子520～780份、水110～160份、减水剂10～22份、钾水玻璃28～48份、三聚磷酸铝3～9.6份；所述石英超细粉的SiO含量≥90％，比表面积≥500m/kg。本发明配方组分混凝土提高了管桩耐腐蚀性，避免酸性介质对桩身混凝土的侵蚀，还能保护管桩内部钢筋不易锈蚀，提高管桩结构强度和使用寿命。
