BC-HPC(I) Special Admixture for High-Performance Concrete in Mines

Brief Introduction

BC-HPC(I) special admixture for high-performance concrete in mines is widely applicable to high-performance concrete structural engineering in mines under the action of sulfate and salt corrosive substances. It is optimally formulated from a variety of organic and inorganic materials, featuring early strength development, high activity, high volume stability, low water demand and excellent corrosion resistance. When incorporated into mine concrete, it can adjust the chemical composition of the cementitious system and maintain the chemical equilibrium of each phase, thereby effectively improving the corrosion resistance and mechanical properties of mine concrete and significantly enhancing its high-performance characteristics.

Product Features

· High Workability: Compatible with all specifications of cement, insensitive to raw material fluctuations, and significantly improves the workability of mine concrete.

· High Activity: Effectively enhances the mechanical properties of mine concrete while optimizing its working performance.

· Low Viscosity: Reduces concrete viscosity by more than 30%, effectively solving the construction difficulty of high-strength concrete.

· Superior Corrosion Resistance: Under simulated saline soil corrosion conditions, the concrete strength loss is less than 5% after 150 dry-wet cycles.

· High Volume Stability: Effectively inhibits autogenous shrinkage and drying shrinkage of mine concrete, and greatly mitigates concrete cracking issues in underground mining environments.

Technical Data

The following data represent typical properties of this product and may be slightly adjusted based on specific customer requirements. (Reference Standards: JCT 1011-2006, JG/T 486-2015, etc.)

Usage Method and Precautions

· Recommended Dosage: The typical dosage of BC-HPC(I) is 5%~30% of the total mass of cementitious materials (internal mixing), which should be adjusted according to the environmental corrosion grade and concrete strength grade.

· Mixing Procedure: Add BC-HPC(I) directly into the mixer simultaneously with cement, aggregates and other raw materials, and mix using conventional concrete mixing procedures.

Packaging and Storage

· Packaging: BC-HPC(I) is available in three supply forms: 25kg valve bags, custom-weighed ton bags, and bulk powder tanker delivery, ensuring convenient loading, unloading and transportation.

· Storage: BC-HPC(I) is hygroscopic. It must be stored in a sealed, light-proof and dry environment with a shelf life of 6 months.

Safety Precautions

· BC-HPC(I) special admixture is non-toxic, non-irritating, non-radioactive, non-flammable and non-explosive. It contains no formaldehyde and is environmentally friendly.

· For personal safety, always wear protective gloves and safety goggles during handling and use to avoid direct skin contact. In case of accidental eye or skin contact, rinse immediately with plenty of clean water. Seek medical attention promptly if irritation persists.
