Our fly ash is a proven solution for a wide range of commercial and industrial uses, including:

• Cement manufacturing
• Ready-mix concrete production
• Concrete block and pipe
• Mineral filler for asphalt roads
• Soil and road base stabilization
• Structural and engineered fill
• Waste stabilization and treatment
• Specialty industrial applications

Fly ash is commonly added to concrete to improve compressive strength, flexural strength, workability, pumpability, and consolidation, while reducing permeability, water demand, heat of hydration, and shrinkage.

As a reliable fly ash supplier in Texas, we focus on quality, consistency, and logistics reliability.

Key Performance Benefits:

• Excellent compaction characteristics
• Slow hardening with low short-term stiffness
• Reduced cracking caused by thermal shrinkage
• Improved long-term durability and strength
• Reduced cement and raw material usage
• Environmentally responsible reuse of coal combustion products

Fly ash is classified as non-hazardous and is widely accepted for use in infrastructure and environmental projects.

Fly ash is one of the most widely used supplementary cementitious materials in the construction industry. When used in concrete and Portland Pozzolana Cement (PPC) applications, fly ash:

• Improves workability and plasticity
• Reduces water demand and lowers heat of hydration
• Minimizes bleeding and segregation
• Delays early-age strength while matching or exceeding long-term strength
• Enhances resistance to permeability and chemical attack

Fly ash also helps mitigate alkali-silica reaction (ASR), reducing long-term cracking and deterioration in concrete structures.

In brick and masonry production, fly ash offers several advantages including lower mixing water requirements, faster drying cycles, improved firing efficiency, and uniform texture and finish.

What is fly ash?

Fly ash is a fine powder produced during the combustion of coal in coal-fired power plants. It is collected from flue gases using electrostatic precipitators or bag filters and is widely used in construction due to its cementitious properties.

Is fly ash hazardous?

No. Fly ash is classified as non-hazardous under the EPA’s Resource Conservation and Recovery Act (RCRA) when properly managed. It is commonly approved for use in concrete, construction, and environmental applications.

What are the benefits of using fly ash in concrete?

Fly ash improves workability, pumpability, compressive strength, and durability while reducing water demand, heat of hydration, and permeability.

Does fly ash make concrete more sustainable?

Yes. Using fly ash reduces the need for Portland cement, which lowers energy consumption and greenhouse gas emissions. It also diverts coal combustion by-products from landfills.

What types of concrete use fly ash?

It is used in Portland Pozzolana Cement (PPC), Roller-Compacted Concrete (RCC), High-Performance Concrete (HPC), and Self-Consolidating Concrete (SCC).

Do you supply fly ash in bulk quantities?

Yes. Hasten Chemical is a fly ash wholesale supplier offering bulk quantities for commercial, industrial, and infrastructure projects.

Where do you supply fly ash?

We supply fly ash throughout Texas, Louisiana, and across the United States, with logistics support for regional and nationwide projects.
