What is Hydraulic Cement?
Hydraulic cement is a material that starts as a liquid, but when applied to a structure and exposed to water, it rapidly dries and hardens. In fact, it can completely solidify within a matter of minutes, as opposed to the many days that average cement may take to dry. Hydraulic cement is used in construction and structural repair work due to this advantageous trait. On top of that, it’s also cost-effective and easy to work with.
What are the components of hydraulic cement?
Hydraulic cement itself is composed of a combination of substances, with four primary components of note. They are alite, belite, celite, and brownmillerite. Alite and belite give it its strength once it is hardened, while celite and brownmillerite help to keep it in its initial liquid state before it is used.
Why is hydraulic cement sulfate resistant?
Moderate sulfate resistant hydraulic cement remains sturdy around sulfates because it has chlorides added into it. This hydraulic cement is useful for structures that are built along coastlines, since they may come into contact with more water than the average structure.
Why do you need a bleeder tube for a foundation?
Bleeder tubes are meant to help the foundation drain out water by letting it flow out underneath them. However, they end up weakening the foundation’s structural integrity since chunks of it are excised from its bottom—the very part that the rest of the home rests on. Large cracks then arise from the bleeder tube setup. Therefore, you should avoid this foundation repair method and application of hydraulic cement.
How long does it take for hydraulic cement to cure?
Although hydraulic cement becomes solid quickly, it can still take around a month for it to complete the curing process. During curing, the concrete needs to maintain a certain level of moisture and sit in a warm temperature range in order for it to harden to its full strength after setting.
What is the product of the reaction of water and cement?
When water is added to these compounds, one of the main products of the reaction is calcium silicate hydrate. Calcium silicate hydrate creates multitudes of tiny fibers when it is formed within the hydraulic cement. These fibers are what toughen the cement overall and make it impervious to water.

Where Can I Use Hydraulic Cement?
Get rid of all dust from the surfaces that will be in contact with the fresh cement. The dust will prevent a good bond between the old masonry surfaces and the fresh mixture.
Why does hydraulic cement expand?
Hydraulic cement expands as it hardens. It expands because the cement contains expansive clays such as bentonite and a few others. Expansive clays start to puff up when in contact with water. The best analogy is adding yeast to flour to make bread. The dough starts to rise increasing its volume.
Is hydraulic cement a Portland cement?
Being a hydraulic cement in itself has nothing to do with expansion, although some hydraulic cements will shrink less than others, but this is due to them being a sulfoaluminate based cement, not a Portland cement and has nothing to do with them being a hydraulic cement.
Does Portland cement shrink?
Many homeowners don't realize that ordinary Portland cement shrinks when it dries. The shrinkage is very little, however, it does shrink. This means that if you patch a crack or a hole using normal Portland cement or bricklayer's mortar, a very tiny leak may form after the cement dries.
Should I Dampen Existing Concrete or Masonry?
Dampen the concrete that will be in contact with the fresh hydraulic cement to get the absolute best bond. It doesn't need to be dripping wet, just spritz it so some water soaks into the dry concrete or masonry surfaces.
