我们都知道氢氧化钾是一种化学用品，在工业等领域起着不小的作用，同时它还可以用来作清洗剂，清洗油垢，效果比较显着，接下来我们了解一下氢氧化钾对混凝土的物理性能产生什么影响。

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、抗掺性能。有氢氧化钾的混凝土，它的抗渗标号比未加剂混凝上的抗渗标号要高。

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

2、混凝土的徐变。掺加氢氧化钾的混凝土的徐变度，比不加剂混凝土的要小，徐变系数也小，故用于预应力混战土时，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，对加入氢氧化钾的混凝土的碳化及锈蚀等方面均有过试验报导。一般，在正常使用下，均未发现有不良的影响。

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、混凝土的干缩性能。掺有氢氧化钾的混凝土，在室温下养护时，前二个月的收缩要略大些，三个月以后则掺剂混凝土的收缩要比未加的小些。

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、抗冻融性。掺有氢氧化钾的混凝土，其容重比未加时要大，说明其密实性好，因而抗冻融性能要好。

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.

以上五点就是氢氧化钾对混凝土的物理性能产生的相关影响，另外氢氧化钾具有引湿性，在潮湿的阴雨天气会吸潮结块。这一方面也要多加注意，还有什么问题就来我们网站http://www.jinhao360.com咨询吧！

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.
