Specification Grade Bottom Ash for Cement, Concrete, and Road Base Applications

We export bottom ash to international buyers who require consistent mineral material for construction and industrial applications. Our role as an exporter is not limited to product shipment—we coordinate technical specifications, grading requirements, documentation, and compliance so buyers receive material suitable for their exact engineering and performance needs. Shipments include bulk quantities processed to meet defined particle size distribution, moisture tolerance, and application compatibility for global projects. Graded and screened bottom ash is widely used as an aggregate substitute and engineering fill material in construction and infrastructure projects. With controlled gradation, uniform particle size, and low carbon content, it is suitable for cement blending, concrete applications, road base layers, embankment filling, and geotechnical works. Predictable performance and dependable compaction make it a reliable material for civil engineering, pavement, and stabilization projects requiring structural support.

Product Overview and Material Characteristics

Graded Mineral Bottom Ash for Construction, Cement, and Infrastructure Applications

The material offered includes multiple classifications such as fine bottom ash, coarse bottom ash, and graded bottom ash, depending on the intended use. For projects requiring predictable performance, we supply uniform bottom ash, consistent quality ash, and controlled size ash to meet engineering specifications.

Available material types may include:

• Screened bottom ash and washed bottom ash for reduced impurities

• Dry bottom ash and low moisture ash for efficient handling and blending

• Low carbon ash where compatibility with cementitious systems is required

• High density ash and high strength ash suited for load-bearing or structural fill

• Blended bottom ash prepared for specific gradation targets

These options allow buyers to select cement grade ash, construction bottom ash, or industrial bottom ash based on technical requirements.
