The invention discloses a kind of preparation processes of prestressed concrete pipe pile, the following steps are included: step 1, weighs following raw material: 30-40 parts of portland cement, 10-20 parts of super finely ground slag, 55-65 parts of sand, 6-12 parts of tetramethyl based quaternary ammonium salt, 5-10 parts of modified calcium-base rectorite, 1-3 parts of spirulina polysaccharide, 1-2 parts of cubic aluminium oxide, 0.2-0.8 parts of polypyrrole pipe, 0.1-0.7 parts of nanometer boron fibre, 60-100 parts of deionized water.Basalt fibre of the present invention is applied in technical field of concrete, fiber mixes the microcrack of matrix, in gap, the continuity of material can be improved, concrete can be cohered simultaneously, to influence water translocation, impermeability is improved, the non-research work of air entrained type small molecule of the tetramethyl based quaternary ammonium salt of addition is adsorbable on the raw materials such as basalt fibre. |
