What is rapid hardening cement and low heat cement?
Rapid hardening cement is a special type of cement that achieves high strength in less time. Normally the strength achieved by conventional cements in 7 days is same as the strength achieved in 3 days. This type of cement is also called as High-Early Strength Portland Cement.
What is low heat cement used for?
Low Heat Cement is designed to provide a lower ‘heat of hydration’ in concrete. This attribute makes it ideal for mass concrete pours where the rate of temperature rise and the maximum temperature achieved must be controlled in order to reduce the risk of thermal cracking.
What is the use of low heat cement?
Low Heat Cement is specially blended to provide a lower heat of hydration in concrete. This unique attribute makes it ideal for mass concrete pours where the rate of temperature rise and the maximum temperature achieved must be controlled in order to reduce the risk of thermal cracking.
What is rapid hardening Portland cement?
Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. A small quantity of gypsum is added to this clinker before grinding to produce the final, very fine powder – Rapid Hardening Portland Cement.
Where is rapid hardening cement used?
Rapid hardening cement is used in areas like road pavements so that the traffic can be opened early. It is also used in manufacturing precast slabs, posts, electric poles, concreting in cold countries.
