In modern concrete technology, the term white powder on cement frequently appears in technical specifications, quality control reports, and job site discussions. This is not a contaminant or a surface efflorescence issue. Instead, it refers to Gro

Architectural concrete has moved beyond structural function to become a design statement. Achieving a consistent white color for concrete is challenging because ordinary gray concrete contains iron-rich cement and dark aggregates. True white concr

Walking across a newly paved driveway, a warehouse floor, or a precast concrete panel, you may notice an unwelcome sight: a chalky, white deposit on the surface. When concrete has white powder, it signals more than a cosmetic flaw. This phenomenon
