The Uses and Types of Hydraulic Cement
People use hydraulic cement for several purposes, and there are different types of hydraulic cement to match them. We’ll list them in this section.
(Normal) Hydraulic Cement
This is the common form of hydraulic cement that lacks any situation-specific tweaks to its formula. It is used on a smaller scale for home, building, and structural repairs. It can fill and smooth over cracking on basements, floors, outdoor walkways, and around pipes. Professionals employ it to stop water from leaking in certain situations, since water cannot get past it once it has hardened.
White Hydraulic Cement
This type of hydraulic cement is identical to normal hydraulic cement utility-wise. However, it contains less magnesium and iron than regular hydraulic cement, which changes its color from gray to white. When the appearance of a building is meant to be white or lighter in hue, white hydraulic cement comes in handy since it won’t leave a dark smudge where it has been applied against a lighter wall or floor.
High Early Strength Hydraulic Cement
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. High early strength hydraulic cement reduces the curing time to about a week. It comes in handy when an edifice that it has been added to must be actively used soon after.
Moderate Heat of Hydration Hydraulic Cement
The reaction between hydraulic cement and water produces a significant amount of heat as a byproduct. Moderate heat of hydration hydraulic cement gives off less heat when it reacts. In some larger constructions, including sizeable foundations and high retaining walls, too much heat could end up leading to more cracks and weakening. This is of course counterproductive when you are trying to create a strong structure. Moderate heat of hydration hydraulic cement is thus used to make those large structures stable.
Low Heat of Hydration Hydraulic Cement
This form of hydraulic cement takes the concept of minimizing water reaction heat even further. There is a tradeoff, however. Low heat of hydration hydraulic cement requires a much longer curing time than other types of hydraulic cement. It is needed for building giant structures, such as gravity dams, which would not be able to remain secure if a lot of heat was generated as the cement solidified.
Moderate Sulfate-Resistant Hydraulic Cement
Sulfates are salts that may exist in the water or soil found outside. When they are near concrete, they can react with it in a way that causes the concrete to expand unevenly, which in turn leads to warping and cracking. 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.
High Sulfate-Resistant Hydraulic Cement
High sulfate resistant hydraulic cement is affected by sulfates even less than its moderate variant. Similar to low heat of hydration hydraulic cement, it gains this advantage in exchange for gaining a longer curing time. A structure that will be exposed to sulfates frequently and in high quantities, such as a dock, can benefit from being constructed with this type of hydraulic cement.
