বর্ডার ভাঙ্গা ৩/৪ ডাউন (Border Vanga Down)

Stone materials are often used for construction because they are strong, durable and very resistant to weather conditions. Stone is extracted from natural deposits called quarrying. The stone blocks are processed by cutting, shaping and polishing them. Some aggregates are used during the process for cleaning, crushing and sorting the stone blocks.
