Silica Fume For High Temperature Concrete
Silica fume for high-temperature concrete is typically sold and transported in bulk or in bags. In bulk, it is usually delivered in pneumatic trucks or railcars. In bags, it is typically packed in 25 kg or 50 kg bags, or as per the customer's requirement.
Description
Description
Silica fume is commonly used in high-temperature concrete applications due to its ability to enhance the strength, durability, and resistance to thermal stress of the concrete. High-temperature concrete refers to concrete that is exposed to temperatures above 100°C, such as in the construction of furnaces, kilns, and other high-temperature industrial applications.
FEATURES:
High silica content
Low carbon content
Low permeability
High specific surface area
Reactivity with other materials in the mix
Resistance to thermal shock and mechanical stress
