A Concrete Cylinder Mould is a precision-manufactured cylindrical steel mould used to cast concrete test specimens for compressive strength testing. The standard size for IS 516 (India) is 150 mm diameter × 300 mm height; ASTM C31 (USA) uses 100 mm × 200 mm or 150 mm × 300 mm cylinders. Cylinder specimens are used instead of cubes for ASTM-method concrete testing and for correlation studies. JS Civil Lab Solutions supplies concrete cylinder moulds in cast iron, mild steel, and high-strength steel, with or without base plates, compliant with IS 516:1959, ASTM C31, and ASTM C39. ISI-marked options available. Call +91 93596 24761 for current pricing and stock availability.
A concrete cylinder mould is a precision-manufactured cylindrical mould — typically made from cast iron, mild steel, or high-strength steel — used to cast concrete test specimens that are later tested in a Compression Testing Machine (CTM) to determine the compressive strength of concrete. Unlike cube moulds (which are standard in Indian practice under IS 516), cylinder moulds are specified for ASTM-method testing and for correlation work between Indian and international standards.
| Test Specimen | Standard | Used When |
|---|---|---|
| 150mm Cube | IS 516:1959 | Standard Indian practice for concrete compressive strength (fck) |
| 150mm × 300mm Cylinder | ASTM C39 / IS 516 | ASTM projects, international contracts, research, correlation work |
| 100mm × 200mm Cylinder | ASTM C39 | High-strength concrete, smaller batch testing |
Note: Cylinder strength (f’c) ≈ 0.80 × Cube strength (fck) — conversion factor used in mixed Indian-international projects.
| Parameter | Specification |
