It is believed that everyone knows that concrete is a necessary product in the construction field. Under the erosion of carbon dioxide, water, chloride ion, sulfate and other media, the damage will accelerate. In order to prolong the service life, Wuhan potassium hydroxide is usually added to the concrete. But do you know what its effect on concrete is? Let's introduce it to you.

　　1、抗冻融性。掺有它的混凝土，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。

　　1. Freeze thaw resistance. The volume weight of the concrete mixed with it is larger than that when it is not added, which indicates that it has good compactness and therefore has better frost resistance.

　　2、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，前两个月的收缩要略大些，三个月以后掺剂混凝土的收缩要比未加的小些。

　　2. Dry shrinkage of concrete. When concrete mixed with potassium hydroxide is cured at room temperature, the shrinkage of the first two months is slightly larger, and the shrinkage of the concrete mixed with agent after three months is smaller than that of the concrete not added.

　　3、抗掺性能。有它的混凝土，它的抗渗比未加剂混凝的抗渗要高。

　　3. Anti Doping property. With its concrete, its impermeability is higher than that of the concrete without admixture.

　　4、混凝土的徐变。掺加的混凝土的徐变度，比不加剂混凝土的要小，徐变系数也小，故用于预应力混凝土时，仍可保留必要的性能。

　　4. Creep of concrete. The creep degree of the concrete with admixture is smaller than that of the concrete without admixture, and the creep coefficient is also smaller, so when it is used for prestressed concrete, it can still retain the necessary performance.

　　5、其它性能，对加入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。

　　5. Other properties, such as carbonation and corrosion of the added concrete have been reported. Generally, under normal use, no adverse effects were found.

　　大家在了解了上述关于氢氧化钾对混凝土的影响，大家都有进一步的学习了。混凝土中加入它能增强使用强度，以达到经济适用的目的。但还要提醒您在添加时要适量，不可过多或过少。

　　You have learned about the above impact of potassium hydroxide on concrete, and you have further learning. Adding it to concrete can enhance the strength of use, so as to achieve the purpose of economic application. But also remind you to add the right amount, not too much or too little.
