The document repeatedly lists the terms "(DAPHACO - ĐỒN)" and "TIEÂU CHUAÅN COÂNG TRÌNH" along with other terms including "(DAPHACO - NHÔM)", "(LION - ĐỒN)", "(L I ON - NHÔM)", and "( ON - Đ H N)". It also lists number ranges like "1.0 - 6.0 (xám)" and "8.0 - 35 (đen)". The document appears to be listing standard terms and specifications related to construction materials and projects but the language is not one I am familiar with so I cannot provide more context.
