How to Stop Efflorescence on Concrete?

Using low alkali portland cement can help reduce efflorescence. A well-graded aggregate, using a low water-to-concrete ratio, and preventing premature evaporation of water during curing are all good ways to reduce mineral salts. And finally, water sources used in construction should be clean, potable, and salt-free.

How to Stop Efflorescence on Concrete?

Efflorescence is a common problem on concrete surfaces, caused by the salt in cement that draws water from the air and on the surface.

The result is a white, powdery substance that can be seen on the surface of the concrete. If left untreated, the efflorescence can lead to further deterioration of the concrete.

Fortunately, there are several steps you can take to stop efflorescence from developing on your concrete. First and foremost, it is important to identify what is causing the efflorescence.

If the concrete was recently installed, the efflorescence could be due to the use of too much water during the installation or inadequate curing.

If the concrete is older, the efflorescence could be caused by a high water table, inadequate sealing, or a lack of waterproofing.

Once the source of the efflorescence is identified, it can be addressed. If the efflorescence is due to the use of too much water during installation, the concrete should be allowed to dry and the excess water should be removed.

If the efflorescence is caused by a high water table, the water table should be lowered by using a sump pump or other methods. If the efflore
