8 Types of Cement and their Uses.

1. Ordinary Portland Cement

It is used in all types of normal construction works. Used in the construction of Buildings, Concrete Roads, Massive concrete dams, Culverts, Retaining walls, etc

2. High Alumina Cement

High alumina cement is the type of cement that is produced by either fusion or sintering 40 % lime, 40 % Bauxite, and 15 % Iron oxide with Silica and Magnesia at high temperatures. – It is resistant to sulfates and acids due to the lower amount of C3A. So, It has industrial application due to being a refractory concrete. – HAC, is best choice where high early strength is necessary. – Used in case of precast constructions

3. Low Heat Cement

Since the heat of hydration is very low thus low heat cement is used in the construction of abutments, concrete gravity dams, retaining walls, etc. If cement with high heat generation e.g. quick-setting cement, is used in these types of constructions, large cracks will appear.

4. Portland Pozzolona Cement

– Due to its low heat generating properties, it is used in construction of the dams and mass concreting works. – In the absence of free lime, resistance to the sulphate attach increases. Therefore, PPC is used in the construction of the sewers and similar works. – In the absence of free lime, resistance to the sulphate attach increases. Therefore, PPC is used in construction of the sewers and similar works.

5. Acid Resistant Cement

– Acid-resistant cement is used for lining chemical apparatus and for building towers, tanks, and other installations for the chemical industry. Soluble glass is also used for preparing acid-resistant and heat-resistant coatings.

6. Expanding Cement

It is is used for repairing concrete and reinforced concrete work because of its quick setting properties. – Water proofing in tunnels and pit shafts. – Underwater and underground construction work. – At a place where water impermeable joints are required.

7. Rapid Hardening Cement

– This cement gains early strength thus it is possible to remove formwork early. – It is generally used in the construction of cement concrete pavements or repairs of existing roads because it is possible to open the traffic early. – It is used in precast construction units of electric poles, posts, slabs, etc. because it takes less time in gaining strength thus molds can be opened quickly..

8. Extra Rapid Hardening Cement

xtra Rapid Hardening Cement is a type of cement that is prepared by adding calcium chloride with rapid hardening cement. The maximum amount of calcium chloride that can be added is 2% by the weight of the cement. With the addition of Calcium Chloride setting time of the cement decreases thus it becomes necessary to transport the place and compact the Extra Rapid hardening Cement within 20 minutes of the mixing. OPC can be stored for about 6 months but ERHC can’t be store for more than a month.
