眾所周知，氫氧化鉀是一種化工產品，在工業等領域起著不小的作用，同時也可用作清洗劑、清洗油垢，效果比較明顯，接下來我們來看看氫氧化鉀對混凝土物理性能的影響。

As we all know, potassium hydroxide is a chemical product, which plays an important role in industry and other fields. It can also be used as a cleaning agent and cleaning oil dirt, with obvious effects. Next, let's look at the impact of potassium hydroxide on the physical properties of concrete.

1、耐摻合性。在混凝土中加入氫氧化鉀后，其抗滲性標號高于未加劑混凝的混凝土。

1. Admixture resistance. After adding potassium hydroxide into concrete, its impermeability grade is higher than that of concrete without admixture.

2、混凝土徐變。用氫氧化鉀配制的混凝土的徐變度比未加劑混凝土的要小，徐變系數較小，故用于預應力混戰土仍能保持必要的性能。

2. Concrete creep. The creep degree of the concrete prepared with potassium hydroxide is smaller than that of the unadded concrete, and the creep coefficient is smaller, so it can still maintain the necessary performance when used for prestressed mixed soil.

3、其他性能，對加氫氧化鉀的混凝土的碳化和銹蝕等方面，已有試驗報導。一般說來，在正常使用下，沒有發現不良影響。

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

4、混凝土的干縮特性。在混凝土中加入氫氧化鉀后，在室溫下養護，前兩個月的收縮要稍大一些，三個月后混凝土的收縮比未加的混凝土要小一些。

4. Drying shrinkage characteristics of concrete. After adding potassium hydroxide into the concrete and curing at room temperature, the shrinkage of the concrete in the first two months is slightly larger, and the shrinkage of the concrete after three months is smaller than that of the concrete without adding.

5、抗凍融。添加氫氧化鉀的混凝土，其容重比未加入時大，說明其密實性好，抗凍融性能較好。

5. Anti-freezing and thawing. The volume weight of concrete with potassium hydroxide is larger than that without potassium hydroxide, which indicates that its compactness and freeze-thaw resistance are good.

上述五個方面都是氫氧化鉀對混凝土物理性能的影響，另外氫氧化鉀具有引濕性，潮濕陰雨天氣會吸潮結塊。更多相關產品信息就來我們網站http://www.shrisa.cn咨詢吧！
