Shrinkage Bar Mould

About Shrinkage Bar Mould

A Shrinkage Bar Mould is a precision laboratory mould used for determining the drying shrinkage of cement mortar and concrete specimens. It is designed to cast standard test specimens that are later used to measure dimensional changes due to moisture loss over time.

This mould is widely used in construction material testing laboratories, research institutions, and quality control departments to evaluate the shrinkage properties of cement-based materials.

Key Features

• High-precision mould for accurate specimen casting
• Robust and durable metal construction
• Smooth inner surfaces for easy demoulding
• Corrosion-resistant and long-lasting design
• Easy to assemble and clean
• Designed as per standard testing specifications

Technical Specifications (Typical)

• Material: Mild Steel / Cast Iron / Stainless Steel
• Shape: Standard shrinkage bar mould (rectangular)
• Specimen Size: As per IS / ASTM standards (commonly 25 mm x 25 mm x 285 mm)
• Finish: Powder-coated / anti-corrosive paint
• Assembly: Two or three-part detachable design

Applications

• Drying shrinkage test of cement mortar and concrete
• Construction material testing laboratories
• Civil engineering research and development
