混凝土基面養護不當應該怎樣補救?

   經環氧地坪施工人員介紹,一般混凝土地面施工后,需要正確合理的養護方式,才能夠保證其正常使用效果。如果養護不當,會造成強度下降,表面起砂起塵,出現坑洼的孔洞,嚴重的出現塊狀的脫落現象。隨著使用時間越來越長,情況也會逐漸糟糕。對于混凝土基面養護不當而造成的一些后果,可以使用環氧地坪漆施工或者使用混凝土密封固化劑的方式進行補救。

 
  下面來給大家介紹兩種補救措施。
 
  方案一:使用混凝土密封固化劑
 
  混凝土密封固化劑是液態,可以滲透進混凝土內部,填補混凝土孔隙,提高密實度。已經出現浮漿、孔洞的混凝土地面,可以分為兩種情況進行補救。
 
  (1)對地面有較高的要求。如果對地面的強度、美觀度都有較高的要求,那就需要重鋪至少3公分的水泥砂漿然后使用混凝土密封固化劑材料進行施工,最后打磨出光澤。這樣地面強度以及美觀程度都能夠達到較高的要求。
 
  (2)簡單防塵要求。如果只要求地面達到簡單的防塵效果,可以地面進行打磨,磨掉表面浮漿,找平后鋪撒材料即可。這樣可以起到提高強度,防塵起砂的作用,但由于孔洞很多,反應不均勻,因此地坪上會出現一些白點,影響美觀。
 
  方案二:施工環氧地坪漆
 
  使用雙組份液態環氧地坪漆,施工時添加石英砂可以配置成砂漿層。環氧砂漿可以對孔洞進行修補。環氧地坪漆施工之前,要先進行打磨找平,然后用砂漿填補孔洞,然后正常施工地坪漆。
 
  注意不要用水泥砂漿填補孔洞,然后施工混凝土密封固化劑。否則會造成地面脫落或者新舊地面顏色不一的情況產生。
 
  According to the construction personnel of epoxy floor, after the general concrete ground construction, the correct and reasonable maintenance method is needed to ensure its normal use effect.If not properly maintained, it will result in decreased strength, sand and dust on the surface, potholes and holes, and serious blocky shedding.As time goes on, things get worse.For some consequences caused by improper maintenance of concrete foundation surface, it can be remedied by using epoxy floor paint or using concrete sealing curing agent.
 
  Here are two remedies.
 
  Solution 1: use concrete sealing hardener
 
  Concrete sealing hardener is liquid, can infiltrate into the concrete interior, fill the concrete porosity, improve the compactness.The concrete floor with floatation and holes can be remedied in two cases.
 
  (1) high requirements for the ground.If there are high requirements for the strength and aesthetics of the ground, it is necessary to relay at least 3 cm of cement mortar and then use concrete sealing curing agent material for construction, and finally polish the surface.In this way, the ground strength and aesthetic degree can achieve higher requirements.
 
  (2) simple dustproof requirements.If only the ground is required to achieve a simple dustproof effect, the ground can be polished, and the surface floater can be rubbed off, and then the material can be spread after leveling.In this way, it can improve the intensity and prevent dust and sand. However, due to many holes and uneven reactions, some white spots will appear on the floor, affecting the appearance.
 
  Plan 2: apply epoxy floor paint
 
  A two - component liquid epoxy floor paint is used.Epoxy mortar can be used to repair holes.Prior to the construction of epoxy floor paint, grinding and leveling shall be carried out, then the holes shall be filled with mortar, and then the floor paint shall be normally applied.
 
  Be careful not to fill the hole with cement mortar and then apply concrete sealing hardener.Otherwise, the ground will fall off or the new and old ground will be different colors.
