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(zhù)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(zhù)，接下來(lái)我們了解一下氫氧化鉀對混凝土的物理性能的影響。
　　We all know that potassium hydroxide is a chemical which plays an important role in industry and other fields. At the same time, it can also be used as a cleaning agent to clean grease scale. The effect is remarkable. Next, we will understand the effect 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 property. The impermeability label of concrete with potassium hydroxide is higher than that of concrete without additive.
　　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(shí)，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 admixture, and the creep coefficient is also smaller. Therefore, the necessary properties can be retained when used in pre-stressed concrete.
　　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(guò)試驗報導。一般，在正常使用下，均未發(fā)現有不良的影響。
　　3. Other properties, such as carbonation and corrosion of concrete with potassium hydroxide, have been reported experimentally. Generally, no adverse effects were 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(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 with potassium hydroxide is cured at room temperature, the shrinkage of the concrete with potassium hydroxide is slightly larger in the first two months and smaller than that without potassium hydroxide after three months.
　　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 concrete with potassium hydroxide has larger bulk density than that without adding time, which indicates that it has better compactness and freeze-thaw resistance.
　　以上五點(diǎn)就是氫氧化鉀對混凝土的物理性能的影響，另外氫氧化鉀具有引濕性，在潮濕的陰雨天氣會(huì )吸潮結塊。
　　The above five points are the effect of potassium hydroxide on the physical properties of concrete. In addition, potassium hydroxide has the ability to induce moisture, which can absorb moisture and agglomerate in wet and rainy weather.
