This standard lays down the requirements for natural structural granite stone used for general construction, monumental work, and facing. It specifies criteria for general quality, permissible defects, dimensions, and critical physical properties including compressive strength, specific gravity, and water absorption.
structural granite
Quick Reference Values
Minimum Compressive Strength1000 kg/cm² (100 N/mm²)
Maximum Water Absorption0.5% by weight
Minimum Specific Gravity2.6
Practical Notes
Structural granite must be visually inspected to ensure it is free from cracks, flaws, and veins that could reduce structural integrity.
Always conduct physical property tests per IS 1121 and IS 1124 before using the stone in critical load-bearing masonry applications.
