Shrinkage bar/prism mould 25×25×285 mm for cement mortar drying shrinkage testing per IS 4031 Part 10 and ASTM C157. Embedded gauge studs for length comparator. JS Civil Lab Solutions India.
The Shrinkage Bar Mould (Prism Mould) is used to cast standard prism specimens for measuring the drying shrinkage of cement mortar and concrete as per IS 4031 Part 10 and ASTM C157. The mould incorporates embedded gauge studs at each end of the prism, allowing precise length-change measurement on a length comparator at specified curing intervals to quantify shrinkage strain over time.
JS Civil Lab Solutions supplies shrinkage bar moulds for cement testing laboratories and concrete durability research.
Cast mortar/concrete prisms, demould at 24 hours, take initial length reading, then store under specified curing/drying conditions, taking periodic length readings on a digital length comparator (ID 1718) at 7, 14, 28 days and beyond per IS 4031 Part 10. Shrinkage is reported as percentage length change.
