我們都知道氫氧化鉀是一種化學(xué)用品，在工業(yè)等領(lǐng)域起著不小的作用，同時(shí)它還可以用來(lái)作清洗劑，清洗油垢，效果比較顯著，接下來(lái)我們了解一下氫氧化鉀對(duì)混凝土的物理性能產(chǎn)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?jié)B標(biāo)號(hào)比未加劑混凝上的抗?jié)B標(biāo)號(hào)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(shù)也小，故用于預(yù)應(yīng)力混戰(zhàn)土?xí)r，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(duì)加入氫氧化鉀的混凝土的碳化及銹蝕等方面均有過(guò)試驗(yàn)報(bào)導(dǎo)。一般，在正常使用下，均未發(fā)現(xiàn)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(yǎng)護(hù)時(shí)，前二個(gè)月的收縮要略大些，三個(gè)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(shí)要大，說(shuō)明其密實(shí)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(diǎn)就是氫氧化鉀對(duì)混凝土的物理性能產(chǎn)生的相關(guān)影響，另外氫氧化鉀具有引濕性，在潮濕的陰雨天氣會(huì)吸潮結(jié)塊。這一方面也要多加注意，還有什么問(wèn)題就來(lái)我們網(wǎng)站http://www.tjxjw.com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.
