Cement | The most popular types of cement
When building a house, finding and choosing materials such as cement is always very important. This is also one of the things that makes it difficult for many homeowners to have enough knowledge and information to choose the best option for their homes.
Whether the investor hires a construction team or uses design and construction services, it is necessary to learn and have a good grasp of the materials. But before learning about the most popular types of cement, we need to understand what it is.
-
What is Cement?
This material is understood as a hydraulic binder, existing in the form of a fine black-gray powder, a finely ground product of Clinker Cement with other additives in appropriate proportions. When mixed with water and sand, stone, it will set and hard as stone immediately, durable, withstanding external impacts very well such as abrasion, weather, shock, etc.
It is made up of fine grinding of clinker, natural gypsum, and additives. When it is in contact with water, hydration reactions will occur and form a slurry called cement paste. Then, due to the formation of hydration products, it begins a setting process followed by a hardening process to finally obtain a material with a certain strength and stability.
Actually, cement in construction can be hydraulic or non-hydraulic. A chemical reaction occurs when anhydrous cement is mixed with water and produces water-insoluble hydrates. Meanwhile, non-hydraulic such as gypsum mortar must be allowed to dry to retain physical strength.

The role of cement:
They are widely applied due to the advantages of simple construction, available starting materials, good mechanical properties, heat and weather resistance, and long service life. In the field of civil construction, this one is the main material for the construction of buildings, houses, bridges, roads, canals, culverts, etc.
Especially in nuclear waste treatment, the role of cementation allows the immobilization of radioactive substances profoundly in the microstructure of cementing materials.

Classification:
Previously, on the market there was only one common type of Portland cement, now there are two types of PCB and PC in parallel. Some special types include sulfate-resistant cement, oil, and gas, expansion, low heat, fly ash cement, etc.
- Cement paste: This is a mixture formed between cement and water. It has practical applications, mainly used in the research of cementitious materials because of its large percentage and dominates many physical and mechanical properties of this material.
- Cement mortar: A mixture of cement, sand, and water. Mortar is the object received when adding sand to the one above.
- Concrete: A mixture of cement, sand, gravel, and water, or depending on the specific case, additives or other substances can be added.
- Some popular brands on the Vietnamese market:
VICEM HA TIEN

Advantages:
- Concrete pouring: high development strength, stability, reasonable formwork removal time, good workability of concrete (ability to maintain slump, ductility) suitable for many structural items.
- Mixing mortar: flexible mortar due to cement has good water holding capacity, easy to fly, smooth surface → smooth wall, limited cracking, limited permeability, high mortar grade.
- Tile and stone tiles: cement has high fineness, fine particle diffusion into brick and wall, good water retention → improve adhesion between mortar, brick and wall, saving glue due to limited Non-adhesive mortar falls to the ground → increase the aesthetics and durability of the work.
- This type can be used for construction in brackish water areas, coastal saline soils, improving resistance to chemical corrosive agents (Cl; SO4; CO2…).
