Who Orders Class F Fly Ash From Us
Built for Batch Plants. Spec-Ready for Every Pour.
Class F fly ash is a technical product for technical buyers — batch plant operators, mix design engineers, and precast producers who need consistent, ASTM C618-approved material delivered on schedule. We stock, load, and deliver in pneumatic tankers straight to your facility.
Ready-Mix Concrete Producers
Class F fly ash can replace 20–30% of Portland cement by mass Penn State Engineering in ready-mix applications. Reduces mix cost, improves workability, and increases long-term compressive strength. Delivered directly to your batch plant.
Precast Concrete
Consistent pozzolanic reactivity for precast mix designs. Improves sulfate resistance and reduces alkali-silica reaction risk. Pneumatic tanker delivery ensures clean, uncontaminated material at your facility.
Soil Stabilization
Fly ash used for soil stabilization on roadway subgrades, building pads, and large-scale earthwork. Reduces plasticity, improves load-bearing capacity, and controls moisture in Texas clay soils.
Flowable Fill & RCC
CLSM (Controlled Low-Strength Material) and roller-compacted concrete applications. Fly ash provides the cementitious content and workability needed for self-leveling trench backfill and mass concrete placements.
Performance Benefits
Why Specify Class F Fly Ash?
Reduces Cement Costs
20–30% Cement Replacement
Portland cement runs approximately $80/ton versus $30/ton for fly ash Penn State Engineering — replacing 20–30% of cement with Class F fly ash delivers measurable cost savings on every yard of concrete produced.
Increases Long-Term Strength
Pozzolanic Strength Gain
Class F fly ash increases late compressive strengths after 28 days Penn State Engineering through continued pozzolanic reactivity. Concrete mixes with fly ash often outperform straight cement mixes at 56 and 90-day tests.
Sulfate & ASR Resistance
Improved Durability
Class F fly ash increases resistance to alkali-silica reaction (ASR) Penn State Engineering and sulfate attack — critical for Texas infrastructure exposed to sulfate-bearing soils and groundwater.
Improves Workability
Better Pumpability & Finish
Fine glassy particles improve concrete workability and pumpability. Reduces water demand in the mix while maintaining slump — beneficial for long pump lines and large placements.
Reduces CO₂ Emissions
Sustainability Credit
Each ton of fly ash replacing Portland cement reduces embodied carbon in the mix. Fly ash is a recycled industrial byproduct — its use diverts material from landfill and contributes to green building certification credits.
Lowers Heat of Hydration
Mass Concrete Applications
Slower pozzolanic reaction reduces heat generation during curing — critical for mass concrete placements, thick slabs, and large foundations where thermal cracking is a risk.
Spec Reference
ASTM C618 Class F — Chemical & Physical Requirements
ASTM C618 requires Class F fly ash to have a minimum of 70% SiO₂ + Al₂O₃ + Fe₂O₃ combined. Concrete Captain Material is tested for fineness, strength activity index (SAI), water requirement, soundness, and autoclave expansion. Certificates of conformance and test reports available on request. TxDOT approved source — documentation available for state and municipal projects.

Common Questions
Class F Fly Ash faq
What is Class F fly ash and how is it different from Class C?
Class F fly ash originates from anthracite and bituminous coals and consists mainly of alumina and silica with lower calcium content than Class C. Penn State Engineering Class C fly ash comes from sub-bituminous coals and has higher calcium content — it’s self-cementing. Class F requires Portland cement to activate its pozzolanic properties. For sulfate resistance and ASR mitigation, Class F is the preferred specification.
How much fly ash can replace Portland cement?
Class F fly ash can replace 20–30% of Portland cement by mass Penn State Engineering in most concrete applications. Your mix design engineer sets the replacement rate based on strength requirements, curing conditions, and project specifications. Call us and we’ll coordinate with your batch plant on delivery quantities based on your replacement percentage.
Does fly ash affect concrete set time?
The time of set may be slightly delayed and early compressive strengths before 28 days may be decreased slightly. Penn State Engineering For most commercial applications this is manageable with mix design adjustments. At 56 and 90 days, fly ash concrete typically meets or exceeds straight cement strengths.
How is fly ash delivered?
By pneumatic tanker direct to your batch plant silo or jobsite. Fly ash cannot be delivered by standard dump truck — it requires pneumatic equipment to transfer the fine powder without contamination or loss. Confirm your silo inlet size and pressure requirements when you call to schedule delivery.
Is your fly ash TxDOT approved?
Yes — our Class F fly ash meets TxDOT requirements for use in concrete on state projects. Certificates of conformance and material test reports are available on request. Call us when you quote if your project requires documentation.
What areas do you deliver to?
Currently delivering to North, Northwest, and East Texas batch plants and jobsites. Call to confirm availability at your specific location — delivery area for fly ash differs from our aggregate network.
