我們都知道氫氧化鉀是一種化學用品，在工業等領域起著不小的作用，同時它還可以用來作清洗劑，清洗油垢，效果比較顯著，接下來我們了解一下氫氧化鉀對混凝土的物理性能產生什么影響。

We all know that potassium hydroxide is a chemical product, which plays a significant role in industry and other fields. At the same time, it can also be used as a cleaning agent to clean oil dirt. The effect is remarkable. Next, let's understand the impact of potassium hydroxide on the physical properties of concrete.

1、抗摻性能。有氫氧化鉀的混凝土，它的抗滲標號比未加劑混凝上的抗滲標號要高。

1. Anti-doping performance. The impermeability grade of concrete with potassium hydroxide is higher than that of concrete without admixture.

2、混凝土的徐變。摻加氫氧化鉀的混凝土的徐變度，比不加劑混凝土的要小，徐變系數也小，故用于預應力混戰土時，仍可保留必要的性能。

2. Creep of concrete. The creep degree of concrete mixed with potassium hydroxide is smaller than that of concrete without additive, and the creep coefficient is also smaller. Therefore, when it is used for prestressed mixed soil, it can still retain the necessary properties.

3、其它性能，對加入氫氧化鉀的混凝土的碳化及銹蝕等方面均有過試驗報導。一般，在正常使用下，均未發現有不良的影響。

3. Other properties, such as carbonation and corrosion of concrete added with potassium hydroxide, have been tested and reported. Generally, no adverse effects are found under normal use.

4、混凝土的干縮性能。摻有氫氧化鉀的混凝土，在室溫下養護時，前二個月的收縮要略大些，三個月以后則摻劑混凝土的收縮要比未加的小些。

4. Dry shrinkage of concrete. When the concrete mixed with potassium hydroxide is cured at room temperature, the shrinkage of the first two months is slightly larger, and after three months, the shrinkage of the concrete mixed with potassium hydroxide is smaller than that of the concrete without potassium hydroxide.

5、抗凍融性。摻有氫氧化鉀的混凝土，其容重比未加時要大，說明其密實性好，因而抗凍融性能要好。

5. Freeze-thaw resistance. The bulk density of concrete mixed with potassium hydroxide is larger than that without it, which indicates that its compactness is good, and therefore its freeze-thaw resistance is better.

以上五點就是氫氧化鉀對混凝土的物理性能產生的相關影響，另外氫氧化鉀具有引濕性，在潮濕的陰雨天氣會吸潮結塊。這一方面也要多加注意，還有什么問題就來我們網站http://www.shrisa.cn咨詢吧！

The above five points are the related effects of potassium hydroxide on the physical properties of concrete. In addition, potassium hydroxide is hygroscopic and can absorb moisture and agglomerate in wet and rainy weather. Pay more attention to this aspect.
