1. Introduction to the Supply Chain Department at Sahi Rasa Company
The Supply Chain Department at Sahi Rasa Company has developed a specialized capability in the production and export of crushed silica aggregates, and SRC represents a key product in this portfolio. The department understands that crushed silica is not merely a coarse sand; it is a functional material with specific properties—strength, chemical inertness, and thermal stability—that make it suitable for demanding applications. An artificial stone manufacturer in Turkey requires crushed silica with controlled particle size and high strength; an AAC concrete producer in Iraq needs silica that reacts with lime to form calcium silicate hydrate; an abrasive manufacturer in Uzbekistan needs silica that is hard and angular for effective cutting. The department's technical team ensures that SRC meets these diverse requirements.
The department sources high-purity silica sand and processes it through crushing, screening, and washing to achieve the ≤2 mm particle size. The final product is tested for particle size distribution, SiO₂ content, moisture, and strength. Certificates of Analysis accompany every shipment.
For clients in Afghanistan, the Kurdistan Region, Iraq, Tajikistan, Uzbekistan, Armenia, Georgia, Turkey, and Syria, the Supply Chain Department at Sahi Rasa Company offers a reliable supply of SRC in the grade and packaging that best suits their needs.

2. Product Overview
Crushed silica SRC is a quartz aggregate with a SiO₂ content of 98% and a particle size of ≤2 mm. It is produced from high-purity silica sand through crushing and screening. The resulting product is characterized by its angular grain shape, high strength, and chemical inertness.
Primary Applications:
Artificial Stone: Engineered stone manufacturers use crushed silica as a filler and aggregate. The silica provides strength, hardness, and chemical resistance to the final product.
AAC Lightweight Concrete: Autoclaved aerated concrete producers use crushed silica as a siliceous raw material. The silica reacts with lime under autoclave conditions to form calcium silicate hydrate, which gives AAC its strength and insulation properties.
Abrasives: Abrasive manufacturers use crushed silica in sandpaper, grinding wheels, and blasting media. The angular grain shape and high hardness make it effective for cutting and surface preparation.
Foundry: Foundries use crushed silica for molds and cores where a coarse aggregate is required.
Construction: Concrete producers use crushed silica as a fine aggregate. Mortar and render manufacturers use it as a filler and aggregate.
Ceramics: Tile manufacturers use crushed silica in body formulations.
