“用于水泥和混凝土中的精炼渣粉（英文版）”介绍

Slag powder used in cement and concrete is a byproduct from the smelting of iron in blast furnaces. It is essentially a latent hydraulic material, meaning it has potential to react with water but requires activation, often provided by the addition of alkalis such as lime or Portland cement itself. In the context of cement and concrete, slag can be ground into a fine powder that is then blended with other materials to create a variety of products with enhanced properties.

When incorporated into cement or concrete, slag powder contributes to several advantages. It improves workability, allowing for easier placement and finishing of concrete. Additionally, the inclusion of slag powder can lead to a denser, more durable matrix, enhancing long-term strength and reducing permeability against water and chemicals, which is critical for structures exposed to harsh environments. Furthermore, its use can reduce heat of hydration, making large volume pours less susceptible to thermal cracking.

From an environmental perspective, using slag powder in cement and concrete is beneficial because it recycles industrial waste and conserves natural resources. It reduces the demand for Portland cement, thereby lowering CO2 emissions associated with cement production. Overall, incorporating slag powder in building materials is a sustainable practice that enhances performance while reducing environmental impact.
