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 Rapid Hardening Composite Sulphoaluminate Cement, a rapid-hardening hydraulic cement mainly composed of anhydrous calcium sulphoaluminate, dicalcium silicate and an appropriate amount of gypsum. It is available in 42.5 and 52.5 grades. The current specification lists initial setting time ≥25 min and final setting time ≤180 min for both grades, with specific surface area ≥350 m2/kg. It is listed for rapid repair, grout, precast, self-leveling and dry-mix applications; final performance must be confirmed by trial mix.
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-binder ratio, admixture dosage, working time, curing condition and application method. Verify compatibility with water reducers, retarders, accelerators and expansive agents using the actual local materials.

Technical Specifications
Specification requirements for rapid-hardening composite CSA Cement grades 42.5 and 52.5.
| Item | Specification Requirement |
|---|---|
| Product type | Rapid-hardening composite sulphoaluminate cement |
| Available strength grades | 42.5 and 52.5 |
| Specific surface area | Grade 42.5: ≥350 m²/kg; Grade 52.5: ≥350 m²/kg |
| Setting time — Grade 42.5 | Initial ≥25 min; final ≤180 min |
| Setting time — Grade 52.5 | Initial ≥25 min; final ≤180 min |
| Flexural strength — Grade 42.5 | 1 d ≥6.0 MPa; 3 d ≥6.5 MPa; 28 d ≥7.0 MPa |
| Compressive strength — Grade 42.5 | 1 d ≥30.0 MPa; 3 d ≥42.5 MPa; 28 d ≥45.0 MPa |
| Flexural strength — Grade 52.5 | 1 d ≥6.5 MPa; 3 d ≥7.0 MPa; 28 d ≥7.5 MPa |

These values are specification requirements, not batch test results. The current product brief does not include 6-hour data. Final performance depends on formulation, water, additives, curing and test method.
Directions for Use / Formulation Reminder
- Conduct a trial mix before use.
- Confirm the water-binder ratio, admixture dosage and working time for the intended application.
- Verify compatibility with water reducers, retarders, accelerators and expansive agents.
- Use actual local raw materials and the intended application and curing conditions.
- Confirm packaging and storage needs before order.
Packaging and Storage
Available packaging includes 25 kg bags and 1000 kg jumbo or bulk bags. Final packaging, palletizing, moisture protection, labeling and export documentation should be confirmed before order. Store the material dry, covered and protected from moisture and rain.

View SolutionProduct-Specific Questions
Is gypsum included in this CSA Cement?
Yes. The controlled product description states that this CSA Cement contains an appropriate amount of gypsum. Compatibility, dosage, working time and final performance must still be verified in the complete formulation.
Can CSA Cement replace Portland cement one-for-one?
Not automatically. Replacement or blending changes setting, workability, strength development and dimensional behavior. The ratio must be selected from the required application and confirmed by a trial mix.
How should 42.5 and 52.5 grades be selected?
Select the grade according to the required early strength, working time and application, then confirm performance under the stated test method and with the actual local raw materials.
