ISIC Fly Ash
Fly Ash is a versatile industrial byproduct widely used in the construction industry for its unique chemical and physical properties. At ISIC, we supply high-quality Fly Ash in two distinct colors : grey and beige — to meet the varied requirements of our clients and applications.
Known for its ability to enhance the performance of construction materials, Fly Ash is commonly used as a supplementary cementitious material (SCM). When blended with cement, it improves workability, strength, and durability, while also contributing to reduced environmental impact by lowering overall cement consumption.
Applications include:
- Concrete production: Improves strength, reduces permeability, and enhances long-term durability.
- Cement manufacturing: Acts as a partial replacement for clinker, reducing carbon footprint.
- Soil stabilization: Enhances load-bearing capacity in geotechnical projects.
- Bricks and blocks: Provides lightweight, strong, and sustainable building materials.
ISIC Natural Pozzolan
Natural Pozzolan is one of ISIC’s essential products, sourced from high-quality volcanic deposits and processed to meet international standards for construction and infrastructure applications. Available in two colors — black and red, our pozzolan is valued for its natural reactivity, consistency, and ability to enhance concrete performance.
ISIC supplies natural pozzolan in forms suitable for blending with cement and concrete, ensuring uniform quality and reliable performance across diverse applications. Its unique chemical composition makes it an ideal choice for sustainable and high-performance construction.
Applications include:
- Cement and concrete production: Enhances durability, reduces permeability, and improves resistance to chemical attacks.
- Infrastructure projects: Used in roads, bridges, and dams for long-term strength.
- Eco-friendly construction: Reduces CO₂ emissions by partially replacing traditional cement.
- Soil stabilization: Improves load-bearing capacity in geotechnical applications.
Through careful processing and a strong focus on sustainability, ISIC provides red and black natural pozzolan that supports infrastructure development locally and internationally. With consistent quality and proven performance, ISIC pozzolan is a trusted choice for environmentally responsible and durable construction projects.
Through precise processing and a focus on sustainability, ISIC delivers basalt that supports infrastructure and industrial projects both locally and globally. With proven reliability, ISIC Basalt is a trusted choice for durable and high-performance construction solutions.
ISIC Basalt
Basalt is one of ISIC’s key mineral products, extracted from high-quality volcanic deposits and processed to deliver consistent strength and durability. Known for its density, hardness, and resistance to weathering, ISIC Basalt meets international standards and serves as a reliable material across multiple industrial and construction sectors.
ISIC provides basalt in a variety of forms and sizes, ensuring that every application benefits from uniform quality and superior performance. Its natural properties make it highly versatile and indispensable for modern infrastructure.
Applications include:
- Construction aggregates: Provides strength and durability for concrete and asphalt.
- Road and railway projects: Used as base material and ballast for long-lasting stability.
- Concrete production: Enhances compressive strength and resistance to wear.
- Insulation materials: Used in the production of mineral wool for thermal and acoustic insulation.
- Industrial uses: Applied in flooring, tiles, and stone wool manufacturing.
ISIC Micro Silica
Micro Silica, also known as silica fume, is one of ISIC’s advanced mineral products, produced as an ultrafine material with exceptional chemical and physical properties. Recognized for its high pozzolanic activity, ISIC Micro Silica significantly enhances the strength, density, and durability of concrete and specialized construction materials.
ISIC provides micro silica in controlled grades to ensure consistent quality and performance across applications. Its extremely fine particles make it a powerful additive, improving both mechanical and chemical resistance in demanding projects.
Applications include:
- High-performance concrete: Increases compressive and flexural strength while reducing permeability.
