Abstract

With the frequent occurrence of natural disasters nowadays, traditional house construction can no longer be adapted to the current needs of people for building living conditions. Over time, traditional house construction presents deeper cracks, seriously endangering people’s safety. This study mainly discusses the modification of nanocomposite particles on the hydrophobicity of concrete. In view of the current concerns of people, this study uses nanocomposites to fill concrete, change the physical properties of concrete, and greatly reduce the hydrophobic properties of concrete. The experiments were divided into 6 groups, and the hydrophobicity of concrete was discussed by changing the amount of nanocomposite particles and the size of nanocomposite particles. The dosage of the nano-composite particles is 0.05 kg, 0.1 kg, 0.15 kg, 0.2 kg, 0.25 kg, 0.3 kg, keeping the quality of the concrete 1 kg, the diameter of the nano-composite particles is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, keeping the quality of concrete is also 1 kg. During the experiment, when the amount of nano-composite particles is 0.15 kg, the hydrophobic property of concrete is reduced by 81%, the hydrophilic property of concrete is increased by 19%, and the hydrophilic property of concrete is the best. When the diameter of the nanocomposite particles is 0.1 mm, the hydrophobic property of concrete is reduced by 79%, and the hydrophilic property of concrete is increased by 18%. The experimental results show that when the amount of nano-composite particles is 0.15 kg and the diameter of the nano-composite particles is 0.1 mm, the hydrophobic property of concrete is the lowest, which is most beneficial to the solidification of concrete. In this case, the building can be made stronger.

摘要

在自然灾害频发的今天，传统的房屋建筑已经不能适应当前人们对建筑居住条件的需求。随着时间的推移，传统房屋建筑出现更深的裂缝，严重危害人们的安全。本研究主要探讨纳米复合颗粒对混凝土疏水性的改性。针对目前人们的担忧，本研究采用纳米复合材料填充混凝土，改变混凝土的物理性能，大大降低混凝土的疏水性能。实验分为6组，通过改变纳米复合颗粒的用量和纳米复合颗粒的大小来讨论混凝土的疏水性。纳米复合颗粒的用量为0.05公斤、0.1公斤、0.15公斤、0.2公斤、0.25公斤、0.3公斤，保持混凝土质量1公斤，纳米复合颗粒直径为0.1毫米、0.2毫米、0.3毫米、0.4毫米、0.5毫米、0.6毫米，保持混凝土质量也为1公斤。实验过程中，当纳米复合颗粒的用量为0.15 kg时，混凝土的疏水性能降低81%，混凝土的亲水性能提高19%，混凝土的亲水性能最好。当纳米复合颗粒直径为0.1 mm时，混凝土的疏水性能降低79%，混凝土的亲水性能提高18%。实验结果表明，当纳米复合颗粒的用量为0.15 kg，纳米复合颗粒的粒径为0.1 mm时，混凝土的疏水性能最低，最有利于混凝土的固化。在这种情况下，可以使建筑物更坚固。
