Scope

Scope: This standard specifies the terms and definitions, classification and marking, general requirements, testing methods, sampling methods and inspection rules, marking, product quality certificates, user manuals, and packaging, transportation, and storage for phosphogypsum-based curb stones (hereinafter referred to as curb stones). This standard applies to curb stones made from cement and phosphogypsum-based engineering aggregates, etc., which are prefabricated by vibration methods or other equivalent methods and placed at the edges of road surfaces, road boundaries, and for drainage purposes. Their visible surfaces may have a surface layer (material) or no surface layer (material), and may be in natural color, colored, or surface-processed. Main technical content: I. Terms and definitions The standard clarifies the meanings of core terms, including: - Phosphogypsum-based curb stones: curb stones made from cement and phosphogypsum-based engineering aggregates, etc., and prefabricated for placement at the edges of road surfaces, road boundaries, and for drainage purposes. - Phosphogypsum-based flat curb stones: curb stones with a top surface flush with the road surface, used to mark the road surface boundaries and protect the road edge. - Phosphogypsum-based upright curb stones: curb stones with a top surface higher than the road surface, used to mark the lane boundaries and guide road drainage. The standard also defines related terms such as concrete flat stones, clarifying the functions and morphological characteristics of various curb stones. II. Classification and marking 1. Strength grades - Linear curb stones are divided into four grades of flexural strength: C3.5, C4.0, C5.0, and C6.0. - Curved and linear cross-sectional L-shaped curb stones are divided into four grades of compressive strength: C30, C35, C40, and C45. 2. Model and specifications - Linear curb stones are divided into H-type, T-type, R-type, F-type, P-type, and RA
