Overview
Xindu slag is a byproduct derived from industrial furnaces, primarily in metal smelting and power generation. It is widely repurposed in construction and infrastructure projects due to its durability and cost-effectiveness. This material is favored for its environmental benefits, as it reduces waste by repurposing industrial residues. Its granular form makes it suitable for various engineering applications, often replacing natural aggregates.
Physical and Chemical Properties
Xindu slag typically exhibits a dark gray to black color, with a granular or lumpy texture. Its density ranges between 2.8-3.0 g/cm³, providing substantial weight and stability for construction uses. Chemically, it is inert and insoluble in water, making it resistant to weathering and chemical degradation. These properties ensure long-term performance in harsh environments, such as roadbeds and concrete mixes.
Main Applications
The primary use of Xindu slag is as a construction aggregate, where it serves as a base material for roads and pavements. Its high compressive strength and density make it ideal for load-bearing applications. Additionally, it is used as a raw material in cement production, where it acts as a supplementary cementitious material (SCM). This not only enhances the cement's properties but also reduces the carbon footprint of construction projects.
Safety and Storage
While Xindu slag is generally low in toxicity, proper handling is essential to minimize dust exposure. Workers should use protective gear, such as masks and gloves, during transportation and application. Storage should be in dry, well-ventilated areas to prevent moisture absorption, which could affect its performance. Bulk storage is common, with measures to avoid contamination from other materials.
B2B Procurement Guide
When procuring Xindu slag, buyers should specify particle size and chemical composition to ensure suitability for their projects. Suppliers often provide certificates of analysis for quality assurance. Prices vary based on quantity and location, with bulk purchases typically offering cost savings. Buyers are advised to compare multiple suppliers and consider logistics costs, as transportation can significantly impact the final price.
