IS 17564:2021 is the Indian Standard (BIS) for precast concrete compound wall panels - specification. This standard specifies the requirements for materials, dimensions, physical properties, and testing of precast concrete panels used for compound or boundary walls. It covers aspects like dimensional tolerances, transverse strength, water absorption, and marking for quality assurance.
Covers the requirements for precast concrete panels specifically designed for compound wall construction.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Minimum Concrete Grade | M25 (25 N/mm² characteristic cube strength) | No absolute minimum; manufacturer declares a class (e.g., C25/30 is common) | BS EN 12839:2012 |
| Reinforcement Cover (Moderate Exposure) | 20 mm | ≥25 mm (For exposure class XC3/XC4, 50-year life, common equivalent to moderate) | BS EN 1992-1-1 (via EN 12839) |
| Water Absorption Limit | Maximum 6% by mass | Maximum 6% by mass (Corresponds to the highest durability class for water absorption) | BS EN 12839:2012 |
| Dimensional Tolerance (Length/Height >1.5m) | ± 5 mm | ± 5 mm (for Class 1), ± 8 mm (for Class 2) | BS EN 12839:2012 |
| Dimensional Tolerance (Thickness) | ± 3 mm | ± 3 mm (for Class 1), ± 5 mm (for Class 2) | BS EN 12839:2012 |
| Minimum Cement Content (Moderate Exposure) | 300 kg/m³ | 300 kg/m³ (for exposure class XC4, a similar environment) | BS EN 206 (via EN 12839) |
| Maximum Water-Cement Ratio (Moderate Exposure) | 0.50 | 0.55 (for exposure class XC3, a similar environment) | BS EN 206 (via EN 12839) |
