相信大家都知道混凝土是建筑領(lǐng)域必用的產(chǎn)品,在二氧化碳、水、氯離子、硫酸鹽等的介質(zhì)的侵蝕作用下會(huì)加速破壞,為延長使用壽命,通常在其中加入氫氧化鉀。但是大家知道它對(duì)混凝土的影響是什么嗎?下面就給大家介紹一下吧。
  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、抗凍融性。摻有它的混凝土,其容重比未加時(shí)要大,說明其密實(shí)性好,因而抗凍融性能要好。
  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、混凝土的干縮性能。摻有氫氧化鉀的混凝土,在室溫下養(yǎng)護(hù)時(shí),前兩個(gè)月的收縮要略大些,三個(gè)月以后摻劑混凝土的收縮要比未加的小些。
  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、抗摻性能。有它的混凝土,它的抗?jié)B比未加劑混凝的抗?jié)B要高。
  3. Anti Doping property. With its concrete, its impermeability is higher than that of the concrete without admixture.
氫氧化鉀
  4、混凝土的徐變。摻加的混凝土的徐變度,比不加劑混凝土的要小,徐變系數(shù)也小,故用于預(yù)應(yīng)力混凝土?xí)r,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,對(duì)加入的混凝土的碳化及銹蝕等方面均有過試驗(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。
  5. Other properties, such as carbonation and corrosion of the added concrete have been reported. Generally, under normal use, no adverse effects were found.
  大家在了解了上述關(guān)于氫氧化鉀對(duì)混凝土的影響,大家都有進(jìn)一步的學(xué)習(xí)了?;炷林屑尤胨茉鰪?qiáng)使用強(qiáng)度,以達(dá)到經(jīng)濟(jì)適用的目的。但還要提醒您在添加時(shí)要適量,不可過多或過少。
  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.
