What is hydraulic cement?

The oldest cements are as old as the construction itself, and how civilization has proceeded and its needs have changed, as well as cement. One type of modern cement is hydraulic cement. Around the beginning of the industrial revolution, hydraulic cement was developed as a way to satisfy the changing needs of the building industry and the people he served. Hydraulic cement concerns any cement that is set and hardened after a combination of water. Most design cements are today hydraulic.

When dry hydraulic cement is mixed with water, some chemical reactions are in the mixture. These reactions form the chemical compounds that contain water, and the formation of these compounds causes the mixture to harden. Due to the nature of the compounds created in these reactions, they are insoluble in water. This means that the tempered cement retains its strength and hardness, even if it is immersed in the water. As a result, it is ideal for brick buildings in wet climates, port structures are in contact with MOřiční water and many other applications.

It is important to distinguish cement from concrete. Although these terms are often used interchangeably outside the construction industry, they refer to different products. For example, the most common type of hydraulic cement is called Portland cement. Portland cement is most often used in the production of concrete, which contains cement, sand, gravel and water.

The cement itself is produced by heating limestone with a small number of other components, such as clay. The mixture is brought to a high temperature in the furnace and the hard substance that results in is referred to as a "clinker". Skinker then breaks into the powder along with a small amount of plaster. The finished product is an ordinary Portland cement. This basic mixture is diverse to create a wide range of Portland cements that are suitable for many specific applications.

One of the common applications for a special hydraulic cement mixture is to repairin and leaks. Some types of cement contain a component that causes cement expansion when building is filled with leaks and holes in concrete or other structural materials. This type of repair is often needed due to the fact that an ordinary Portland cement is slightly shrinking when it dries. Places like basements in wet climate areas are particularly susceptible to leaks. However, these special mixtures can be difficult for newcomers to work, because once it is mixed, the material remains feasible for only 10 to 15 minutes.
