Excellent Cement- A Great House Foundation
One should pay attention to the details that ensure that the foundation will remain dry and free of cracks for as long as it has a house to hold up because a house foundation is forever. If someone has paid proper attention to the foundation, then his building foundation will be moisture free, shield against the cold, and prevent movement of the earth around it. The most important thing about a strong house foundation is that it should last forever. Concrete is the most essential building material that is being used for building house foundation, and most concrete mix designs use the same type of raw materials: cement, water, and aggregates, in different ratios. And if someone wants to have unique qualities in the concrete, then they will add additional materials to the concrete such as:
Fibers: fibers and concrete admixture help to enhance the strength of the concrete.
Plasticizers: plasticizers will make free-flowing and better workability of the concrete.
Retarding agents: retarding agents help to reduce the rate of setting of cement.
Accelerating chemicals: in contrast to retarding agents, the accelerating chemicals increases the rate of setting of cement.
Corrosion inhibitors: these materials will help to reduce corrosion of steel rebars.
Most people get confused with the terms cement and concrete, but they do not know that cement and concrete often are used interchangeably. For clarification, cement is an ingredient of concrete, and concrete is a mixture of aggregates and paste. Sand and crushed stones are used as aggregates in concrete, and the mix of water and portland cement is the paste in concrete.
There are about eight types of cement manufacturing in the companies to meet different physical and chemical requirements for specific applications, but almost all portland cement is similar. Building a strong foundation is not as simple as digging a hole and pouring some concrete into it. One should pay attention to the soil condition, water tables, and even on the quality of the backfill as well.
Different types of cement have different purposes and functions in construction like type 1 cement is suitable for most uses. Type 2 is used for the construction of structures present in water or soil containing moderate amounts of sulfate, Type 3 provides high strength in a short period of time. Type 4 cement is used for huge concrete buildings such as dams, Type 5 cement prevents chemical attack. Type 6, 7, and 8 are used to make air-entrained concrete.
