Product Detail
TGA-6 Fly Ash ActivatorUsed to activate the cementitious activity of fly ash and improve strength development when fly ash is added: under the specified test conditions, 7d activity increases by ≥8% and 28d activity increases by ≥10%, supporting large-volume utilization of fly ash.
The product is an amber to pale yellow clear liquid (subject to actual measurement of the delivered batch). It can be directly metered into the mixing water and is suitable for conventional blending processes at batching plants and in cement grinding.
What really holds buyers back once fly ash content goes up
Replacing part of the cement with fly ash can reduce material costs and improve workability of the mix, and it is also the main pathway for utilizing fly ash as a resource. However, when the content increases, two problems are commonly encountered: first, the pozzolanic reaction of fly ash is slow, and early strength development cannot keep pace, which slows down formwork removal, prestressing tensioning, and formwork turnover; second, fly ash from the same batch often comes from mixed sources and has highly variable activity, making mix proportion trial results unstable, so procurement and quality control departments are reluctant to use it freely.
TGA-6 targets exactly this main line: through chemical activation, it accelerates the participation of reactive silica-alumina components in fly ash in the reaction, mobilizing the cementitious activity that originally is mainly released after 28d. For buyers, judging whether such an activator is worth introducing mainly depends oncomparison data under the same mix proportion and the same fly ash batch—TGA-6's indicators are 7d activity increase ≥8% and 28d activity increase ≥10%. Before formal procurement, it is recommended to conduct comparative paste/mortar trials using your own fly ash, with actual measured values as the basis.
TGA-6 liquid sample appearance: amber to pale yellow clear liquid
TGA-6 is a liquid formulation and does not require on-site dissolution. It can be added with the mixing water via an admixture metering pump, or metered and added together with fly ash during grinding. The advantage of the liquid formulation is that the dosage is easy to control online and batch-to-batch consistency is easier to maintain, making it especially suitable for batching plants where the fly ash source is not fixed and the dosage needs to be fine-tuned by batch.
The specific dosage and addition point depend on the fly ash quality grade, target strength grade, and existing mix proportion, and must be determined through trial mixing. Detailed blending plans and technical service arrangements can be discussed upon inquiry after stating your fly ash source and target strength grade.
Typical application scenarios
High-volume fly ash concrete: Projects that need to increase the fly ash replacement ratio while ensuring early strength development, such as road bases, mass concrete, and precast components, used to mitigate the low early strength caused by higher content.
Production of fly ash-based cementitious materials: Grinding stations using fly ash as the main supplementary cementitious material, combined with TGA-6 to improve the strength level of finished products and increase the utilization value of low-activity fly ash.
Solid waste resource utilization projects: Commercial concrete plants or building materials enterprises with large local fly ash stockpiles that need to establish a stable consumption channel, using the activator to convert stockpiled fly ash into a stably usable cementitious component.
Key points to check when comparing purchases
Comparison item | Recommended practice |
|---|---|
Activity improvement data | Require usingyour own fly ash samplefor 7d / 28d mortar comparison, rather than only looking at supplier standard sample data |
Compatibility with water reducers | Trial mix under the existing polycarboxylate/naphthalene water reducer system, and observe whether slump change over time and setting time are abnormal |
Metering and addition method | Confirm the adaptation plan for the liquid formulation with existing metering pumps and mixing water pipelines |
Batch stability | Request factory inspection data by batch, and re-trial to confirm dosage when the fly ash source changes |
Procurement FAQ
- Under what conditions are the 7d increase ≥8% and 28d increase ≥10% data obtained?
- These are the activity improvement indicators of this product, referring to comparison with a control group without activator under the specified test conditions. Actual engineering results depend on fly ash grade, mix proportion, and curing conditions. Please verify by trial mixing with your own fly ash before procurement, with actual measured results as the basis.
- The fly ash source changes frequently; can it still be used?
- Fluctuation in fly ash activity with source is common in the industry. It is recommended to retain samples by batch and conduct rapid comparative trial mixing, and fine-tune the TGA-6 dosage based on the trial results. Specific operating details can be confirmed with our technical staff upon inquiry.
- Is it solid or liquid? How is it added?
- This product is a liquid formulation, which can be added with the mixing water through the admixture metering system, or metered and added during grinding. The specific addition point is determined by the trial mixing plan.
- What are the minimum order quantity, packaging, and lead time?
- Please obtain the latest quotation for packaging specifications, MOQ, price, and lead time through inquiry, subject to confirmation based on order quantity and destination.
- Can samples be provided?
- For samples and technical support arrangements, please state your project situation and fly ash source in the inquiry, and we will reply with the available samples and trial mixing support methods accordingly.
