This 42.5 white Portland cement from Guangxi Siwei Materials Technology Co., Ltd is a pure white hydraulic binder designed for applications where colour consistency is critical. It achieves a brightness of 90% and is supplied as a white powder in 25 kg weatherproof bags. The material is air-dried within 2-3 hours and has a shelf life of 6 months, making it suitable for projects requiring immediate use or short-term storage.
The cement is composed primarily of calcium silicate, with measured properties including a 3-day compressive strength of 35 MPa and a 28-day compressive strength of 47 MPa. Its 3-day flexural strength is 5.5 MPa, rising to 8 MPa at 28 days. The initial setting time is 165 minutes, with a final setting time of 200 minutes, and a 45 µm fineness of 3.0%. These values align with typical white Portland cement standards, which often require fineness below 5% and setting times within 45-375 minutes for optimal workability and early strength development.
Architects and contractors use this cement for decorative concrete, terrazzo, and white mortar in residential and commercial projects. It is particularly valued in markets where aesthetic appearance is a priority, such as façade work, precast panels, and artistic installations. Buyers should confirm bulk availability, as the listing specifies bagged supply, and verify compatibility with local admixtures or pigments for custom colour matching.

Before ordering, verify the cement’s brightness and fineness, as these directly impact the aesthetic and structural performance of the final product. Request a certificate of analysis or third-party test report to confirm the 90% brightness and 3.0% fineness values, as well as the compressive and flexural strength results. Ensure the supplier can provide consistent quality across batches, as variations can affect project outcomes.
Confirm logistics details, including packaging integrity for 25 kg bags and the supplier’s ability to handle bulk orders. Ask about lead times for production and shipping, as well as the preferred Incoterms, such as FOB or CIF, to clarify cost and responsibility divisions. Payment terms, such as L/C or T/T, should also be agreed upon in advance to avoid delays.
Inspect a sample batch for colour consistency, setting time, and strength development before committing to a large order. For decorative applications, test the cement with intended pigments or admixtures to ensure compatibility. Request documentation such as the mill test certificate, which provides batch-specific data, and confirm that the cement meets the required standards for your project’s location.
