High-performance hydrophobic early-strength grouting material
The invention provides a high-performance hydrophobic early-strength grouting material, which is prepared from the following components in parts by weight: 35 to 40 parts of main cementing material, 7 to 10 parts of auxiliary cementing material, 30 to 35 parts of river sand of 10 to 30 meshes, 10 to 15 parts of river sand of 30 to 50 meshes, 5 to 10 parts of river sand of 50 to 70 meshes, 0.01 to 0.03 part of water reducing agent, 0.05 to 0.1 part of defoaming agent, 0.01 to 0.03 part of hydrophobic powder, 0.02 to 0.05 part of expanding agent and 0.1 to 0.5 part of modified carbon nano tube, the modified carbon nano tube is prepared by modifying the surface of a carbon nano tube by adopting seaweed gel; the main cementing material is ordinary Portland cement and calcium aluminate cement; the auxiliary cementing material is a mixture of fly ash and silicon powder in a mass ratio of 5: 2. The grouting material provided by the invention is not only high in curing speed, but also good in mechanical property and excellent in impermeability.
本发明提供了一种高性能憎水性早强灌浆料，以重量份计，包括以下组分：主胶凝材料35‑40份，辅助胶凝材料7‑10份，10‑30目河砂30‑35份，30‑50目河砂10‑15份，50‑70目河砂5‑10份，减水剂0.01‑0.03份，消泡剂0.05‑0.1份，憎水粉0.01‑0.03份，膨胀剂0.02‑0.05份，改性碳纳米管0.1‑0.5份，所述改性碳纳米管是采用海藻胶对碳纳米管表面进行改性制得；所述主胶凝材料是普通硅酸盐水泥、铝酸钙水泥；所述辅助胶凝材料是粉煤灰、硅粉以质量比为5:2的混合物。本发明提供的灌浆料不仅固化速度快，且力学性能好，抗渗性能优异。
