Ralph Rapat International Co., Ltd., based in Bangkok, Thailand, offers cement clinker that serves as the primary hydraulic binder for Portland cement production. The product is supplied as nodules or lumps and conforms to Types I, II and V according to ASTM C1157 specifications. Although the supplier is located in Thailand, the clinker originates from Iranian mines and is typically shipped FOB from Iranian ports. Packaging options listed include 25 kg and 50 kg bags, 1‑ton jumbo bags and bulk loading for large consignments.
Standard clinker particle size ranges between 3 mm and 25 mm, with a bulk density of approximately 1450 kg m‑3, which aligns with common industry practice. Typical chemical composition targets 60‑65 % CaO, 20‑25 % SiO2, 2‑5 % Al2O3 and 0.5‑3 % Fe2O3, ensuring compatibility with downstream grinding processes. Moisture content is usually kept below 1.5 % to prevent premature hydration during storage and transport. The inclusion of gypsum as a set‑retarder is standard to control the early setting time of the final cement.
Buyers such as cement factories, ready‑mix concrete producers and large construction firms source this clinker for blending with other materials to achieve desired performance. Importers should verify the minimum order quantity, lead time and preferred Incoterms directly with Ralph Rapat International before finalising purchase. Because the supplier does not disclose payment terms in the listing, these need to be clarified during negotiations.
