Cement is the fine grey powder that is mixed with water and other substances to make concrete. It is a major key building material in both residential and commercial construction work. Cement is essential because it binds or holds the concrete mix together, giving it a strength. In the construction industry, there are different types of cement. The differences between each cement type are its properties, uses and composition materials used during the manufactured process. Here you can see the different types of cement and for what it are used in the construction industry.
Ordinary Portland cement:
Ordinary Portland cement is the most common cement used in the construction industry. It has a low resistance chemical attack, and it has a medium rate of hardening. Out of the total production of cement, it accounts for about 80% to 90%. The ordinary Portland cement has the rate of higher strength, and the rate of heat hydration is medium. Ordinary Portland cement is used for joining the masonry. It contains plaster of Paris which gives perfect wall finishing and used for construction.
Rapid hardening cement:
The rapid hardening cement is similar to ordinary Portland cement; it develops its strength rapidly, so it is called high early strength cement. Their rapid development rate is due to the higher fitness of cement particles which gives a greater surface area. This is used for the construction of the essential structures and underwater works.
Sulphate resisting cement:
The sulphate resisting cement will come in direct contact with the soil. The sulphate reacts with calcium hydroxide to form calcium aluminate. The effect of this attack will be the result of the expansion and distribution of hydrated cement paste. This attack is known as the sulphate attack. It will significantly accelerate in the case of alternate wetting and drying in the marine structures. It is used in the construction of the water treatment works and also in the marine systems.
Coloured cement:
Coloured cement can be used as cooling cement where it is required for any assist purpose. It is produced by mixing 5-10% mineral pigments with ordinary cement. Initially combining colouring cement materials can provide the desired colour for cement. It can be used for external finishing of walls and floors, manufacturing tiles, precast stones, garden paths, swimming pools and tennis courts.
Air entering cement:
Air entering cement produce by adding indigenous as entraining agents such as resins, glues, sodium salts of sulphate. The cement is especially suits to improve the workability with the smaller water-cement ratio and improve the frost resistance of concrete. It can also be used in the frost resistance of concrete.
Final thoughts:
The details mentioned above will be useful for the construction of your building. These are the essential things to be considered about the cement while you are constructing a new building, make a use of it for an efficient process. Select a good quality cement and build a strong building.
