Extra Rapid Hardening cement sets quickly so it is suitable for concrete in cold weather.
In the case of this type of cement, we can remove shuttering and formwork earlier as compared to OPC cement. This shuttering and formwork can be used for other work.
Extra rapid hardening cement is lighter in weight compared to conventional cement.
Extra Rapid hardening cement is best where early strength is required within a short period of time.
Extra rapid hardening cement gives higher strength than Rapid Hardening cement.
This type of cement has good sulphur resistance.
The curing period of extra rapid hardening cement is less as compared to ordinary Portland cement which makes it Economical.
The cost of Extra rapid hardening cement is comparatively high than other types of cement.
In the extra rapid hardening cement there may be chances of developing crack due to higher heat of hydration.
Extra rapid hardening cement is not suitable for the massive concreting work because it generates Higher heat of hydration as compared to other types of cement.
The storage of the Extra Rapid Hardening cement is to be done with great care otherwise a little moisture will Harden the cement.
Extra rapid hardening cement cannot be used after one month of its manufacturing.
Extra Rapid Hardening cement is used the construction activities in waterlogged areas.
Extra rapid hardening cement is widely used in the construction of roads where it is not possible to stop the traffic for a longer time, this cement will allow the foot traffic within 4 to 5 hours and vehicles within 8 to 10 hours.
Extra rapid hardening cement is best suitable for the concreting work in extremely cold climate conditions which will resist the concrete from freezing.
Extra Rapid Hardening cement can be used for the construction of foundations for heavy machinery and equipment in the factories because machinery required to be installed immediately.
Extra rapid hardening cement has a property of early strengthening and hardening due to which it is widely used for the repair works of concrete cracks in Dams and roads.
As this Cement has good sulphur resistance, it can be used to sites where there is a high chance of sulphate attacks.
Quick-setting cement: This type of cement typically sets and hardens within 10 to 30 minutes. It is commonly used for small-scale repairs such as filling cracks, anchoring objects, or patching damaged concrete surfaces. Quick-setting cement is available in powder form and can be mixed with water to form a paste that is then applied to the damaged area.
Fast-setting concrete mix: This pre-mixed product contains a blend of cement, sand, and aggregates designed to set and harden rapidly. It is suitable for larger repairs, such as repairing concrete slabs, steps, or sidewalks. Fast-setting concrete mix is available in bags and can be mixed with water according to the manufacturer's instructions.
Hydraulic cement: Hydraulic cement is a type of cement that sets and hardens when it comes into contact with water. It is known for its rapid-setting properties and high strength. Hydraulic cement is often used for quick repairs of leaks in concrete structures, such as water tanks or basements. It can be applied by simply mixing it with water to form a paste and then applying it to the damaged area.
High-Early-Strength Cement (Type III): As mentioned earlier, Type III cement, commonly known as high-early-strength cement, is designed to develop strength rapidly. It gains significant strength within a few days, allowing for quicker removal of formwork or application of loads.
Calcium Aluminate Cement (CAC): Calcium aluminate cement is a fast-setting cement that can achieve high early strength. It contains calcium aluminates as the primary hydraulic component, which contributes to its rapid hardening properties. CAC can develop significant strength within 24 hours, making it suitable for time-sensitive projects.
Supplementary Cementitious Materials (SCMs): Incorporating supplementary cementitious materials, such as silica fume or fly ash, into the cement mix can enhance its early strength development. These materials react with calcium hydroxide, a byproduct of cement hydration, to form additional cementitious compounds. This accelerates the overall hydration process, resulting in faster strength gain.
Rapid Hardening Cement: Rapid hardening cement, such as Type III Portland cement, is designed to achieve high early strength and faster drying times. It gains strength quickly, allowing for faster construction progress and reduced waiting times. This type of cement is commonly used in time-sensitive projects where early strength development is critical.
Self-Leveling Cement: Self-leveling cement is a fast-drying cementitious material that is fluid in consistency and can flow and settle into level surfaces. It is often used for quick repairs or leveling uneven concrete surfaces. Self-leveling cement typically dries rapidly, allowing for the application of floor coverings or other finishes in a shorter timeframe.
Quick-Drying Concrete Mixes: Some manufacturers offer quick-drying concrete mixes that are specifically formulated for fast drying times. These pre-mixed concrete products usually contain additives and accelerators that promote rapid hydration and drying. They are convenient to use and can significantly reduce construction schedules.
