Additive for improving impermeability of marine concrete and preparation method thereof
The invention discloses an admixture for improving the impermeability of marine concrete and a preparation method of the admixture, and belongs to the technical field of concrete admixtures. The admixture for improving the impermeability of the marine concrete comprises the following components in parts by weight: 100 parts of tackifying modified lignocellulose nanofibers, 10-20 parts of sodium dodecyl benzene sulfonate, 10-15 parts of a high-efficiency water reducing agent and 100-150 parts of silica fume. The tackified and modified lignocellulose nanofiber and silica fume are used as main raw materials, and are matched with the water reducing agent and the sodium dodecyl benzene sulfonate for improving the workability, so that the impermeability of the marine concrete can be improved, and the compactness of the marine concrete can be improved by reducing the water cement ratio; further, the mechanical strength and the impermeability of the marine concrete are improved.
本发明公开了一种提高海工混凝土抗渗性能的外加剂及其制备方法，属于混凝土外加剂技术领域。所述提高海工混凝土抗渗性能的外加剂的组分按重量份计包括：增黏改性木质纤维素纳米纤维100份、十二烷基苯磺酸钠10～20份、高效减水剂10～15份和硅灰100～150份。本发明通过以增粘改性的木质纤维素纳米纤维和硅灰为主要原料，配合减水剂及提高和易性的十二烷基苯磺酸钠，不仅能够提高海工混凝土的抗渗性能，还能通过降低水灰比提升海工混凝土的密实程度，进而提高海工混凝土的力学强度和抗渗性能。
