Vicem But Son Cement Joint Stock Company is a Vietnam-based building materials company primarily engaged in the manufacture, processing, and distribution of cement, clinker, and related construction materials. The company operates as a key subsidiary of the state-owned Vietnam National Cement Corporation (VICEM). Its core product and service offerings encompass Portland blended cement (PCB30, PCB40, and premium slag-blended variants); Ordinary Portland cement (PC40, PC50); specialized cements, including sulfate-resistant, low-heat, and high-early-strength Portland cements engineered for marine and hydraulic infrastructure; masonry cement (MC25); commercial clinker (CPC50); unburnt building bricks; and processed mineral aggregates extracted from its licensed limestone and clay quarrying concessions. Additionally, the company provides multimodal logistics, warehousing, and port handling services; inland waterway and roadway freight transportation; and technical support, installation, and maintenance services for cement manufacturing equipment. Vicem But Son serves industrial, civil construction, and infrastructure projects across northern and north-central Vietnam, while exporting clinker and packaged cement to regional markets in Asia. In recent operational developments, the company has accelerated its green transition and circular economy initiatives by expanding industrial waste co-processing technologies, utilizing refuse-derived fuels (RDF), industrial sludge, and fly ash/slag to substitute traditional coal and virgin raw materials, significantly curbing carbon emissions and production costs. The company has also integrated waste heat recovery (WHR) power generation systems across its production kilns to enhance energy self-sufficiency, while actively adjusting its operational mix toward higher-margin, specialized cements and optimizing distribution channels to address regional supply-demand dynamics. Founded in 1997, Vicem But Son Cement Joint Stock Company is headquartered in Ha Nam Province, Vietnam.
