CSA Cement
Rapid-Hardening Composite Sulphoaluminate Cement for Mortar and Grout Systems
CSA Cement is a specialty cementitious material for rapid-hardening mortar, grout, tile adhesive, repair products and blended binder systems.
Product Positioning
- Rapid-hardening cementitious material
- Mortar and grout formulation support
- Adjustable setting direction
- Dry mix mortar applications
Product Overview
Quick answer: CSA Cement is a rapid-hardening composite sulphoaluminate cement (anhydrous calcium sulphoaluminate, dicalcium silicate and gypsum-based components) that hardens by forming ettringite. Because the sulfate carrier is built in, it works as delivered. It is available in 42.5 and 52.5 grades and reaches its grade strength at 3 days rather than 28: 42.5 grade 1-day compressive strength ≥30 MPa and 3-day ≥42.5 MPa; 52.5 grade 1-day ≥40 MPa and 3-day ≥52.5 MPa, with initial set ≥25 min and Blaine fineness ≥350 m2/kg. It is used for rapid repair mortar, non-shrink grout, self-leveling compound and tile adhesive.
CSA Cement is a rapid-hardening composite sulphoaluminate cement used in cement-based mortar and grout systems. It is suitable for products that require early strength target, controlled setting and dry mix mortar formulation support.
Final performance depends on formulation design, raw materials, water amount, additives, curing condition and application method. For CSA Cement, the low-carbon value should be considered together with rapid-hardening repair, grout and dry mortar applications, where binder selection, curing and field testing determine the final result.

Typical Technical Data
Typical values from supplied product information for CSA Cement 42.5 and 52.5 grades.
| Item | Typical Value / Supplied Information |
|---|---|
| Product type | Rapid hardening composite sulphoaluminate cement |
| Main mineral direction | Anhydrous calcium sulphoaluminate, dicalcium silicate and gypsum-based components |
| Available strength grades | 42.5 and 52.5 grades according to supplied product information |
| Specific surface area | >=350 m²/kg |
| Setting time | Initial >=25 min; final <=180 min |
| Compressive strength 42.5 grade | 1 d >=30.0 MPa; 3 d >=42.5 MPa; 28 d >=45.0 MPa |
| Compressive strength 52.5 grade | 1 d >=40.0 MPa; 3 d >=52.5 MPa; 28 d >=55.0 MPa |
| Flexural strength 42.5 grade | 1 d >=6.0 MPa; 3 d >=6.5 MPa; 28 d >=7.0 MPa |

The above values are typical data from supplied product information. Final performance depends on formulation design, raw materials, water amount, additives, curing condition and application method.
Typical Starting Dosage
CSA Cement can be used as a standalone rapid-hardening binder or blended with OPC / white cement.
| Use | Starting Direction |
|---|---|
| As standalone binder | Used directly as a rapid-hardening cementitious system |
| Blended with OPC or white cement | Up to 30% of total cementitious |
Starting point for formulation testing only. Final dosage and blend ratio must be verified by lab trial.
Directions for Use / Formulation Reminder
- Use as a specialty cement component or cementitious material direction within a verified mortar system.
- CSA Cement is not a one-size-fits-all solution; final setting and strength depend on formulation balance and raw materials.
- Trial mix should verify water amount, additive compatibility, gypsum or sulfate balance, sand grading and curing condition.
- Adjust retarder, accelerator, water reducer, polymer and defoamer according to working time and application method.
- Confirm packaging and storage needs before order.
Packaging and Storage
Packaging options can be discussed according to order quantity, shipping method and buyer handling requirements. Common options may include 25 kg bags and jumbo bags / bulk bags. Final packaging, palletizing, moisture protection, labeling and export documentation should be confirmed before order. Materials should be stored dry, covered and protected from moisture and rain.

Is this a finished mortar product?
It depends on the product type. Binder and component products are used in formulation systems, while premix or mortar products still need project and application verification.
What information should I provide before requesting samples?
Please send your application, target performance requirement, local raw materials, water control needs, packaging requirement and destination market.
Does final performance depend on formulation?
Yes. Final performance depends on formulation design, raw materials, water amount, additives, curing condition and application method.

Send us your application, target performance requirement, local raw materials, packaging requirement and destination market. We will suggest a suitable product path for sample discussion and testing.
Send Your InquiryMechanism Explanation
CSA Cement should be evaluated as part of a complete cementitious system. Its effect is influenced by binder chemistry, sulfate balance, calcium source, water amount, aggregate grading, additives, curing condition and application method. For dry mix mortar and concrete-related products, trial testing should confirm setting behavior, workability, early strength target, shrinkage-related performance and final application suitability before commercial use.
Additional FAQ
Can this product be used without formulation testing?
No. Final performance should be verified by trial mix and testing because local raw materials, additives, water control and curing conditions can change the result.
Can you help compare this product with other binder options?
Yes. We can discuss the application, target performance requirement, local material information and packaging needs before suggesting a suitable product path for sample discussion.
