High Alumina Cement Properties:
High alumina cement, also known as calcium aluminate cement, is a type of cement that is manufactured by burning a mixture of limestone and bauxite at a high temperature. It has several unique properties that make it suitable for specific applications.
1) High Early Compressive Strength and High Heat of Hydration:
High alumina cement exhibits high early compressive strength, which means it gains strength rapidly after being mixed with water. This property makes it suitable for applications where quick setting and early strength development are required, such as in emergency repairs or construction in cold weather conditions. Additionally, high alumina cement has a higher heat of hydration compared to ordinary Portland cement. Heat of hydration refers to the heat released during the chemical reaction between cement and water. The higher heat of hydration of high alumina cement can lead to higher temperatures during curing, which can be advantageous in cold regions as it helps in accelerating the setting and hardening of the cement.
2) Unsuitability for Cold Regions:
Contrary to the second statement, high alumina cement is actually suitable for use in cold regions. Its high early compressive strength and high heat of hydration make it ideal for applications in cold weather conditions where ordinary Portland cement may not perform well. The rapid setting and early strength gain of high alumina cement allow for quick construction and repair in cold weather, reducing the risk of damage caused by freezing temperatures.
Correct Answer:
Therefore, the correct answer is option 'A' - only statement 1 is correct. High alumina cement indeed has high early compressive strength and high heat of hydration, making it suitable for various applications. However, it is incorrect to say that high alumina cement is not suitable for use in cold regions.
