What Is the Shrinkage Bar Mould Used For?
Cement and concrete laboratories, quarry testing rooms and engineering colleges use it for mortar-bar tests that show whether an aggregate is likely to react expansively with the alkalis in cement. Bars cast with the reference pins are stored under the test conditions and measured at intervals on a length comparator. Assemble the parts firmly, oil the faces lightly and clean the mould straight after demoulding.
Frequently Asked Questions
What test is the Shrinkage Bar Mould for?
It casts specimens of cement–aggregate combinations for measuring potential expansive alkali reactivity, the mortar-bar test that shows whether an aggregate may cause expansion in concrete.
What comes with the mould?
A base plate and four smooth stainless steel reference pins are supplied with it, so the mould is ready for casting once assembled.
How is the mould held together?
Its mild steel parts are tight-fitting and stay firmly held together when assembled, which stops mortar leaking out at the joints during casting.
Who manufactures the Shrinkage Bar Mould?
Jain Laboratory Instruments Pvt Ltd, which trades as JLab, manufactures it in Ambala, Haryana, for direct sale to laboratories, institutions, dealers and importers.
OEM Manufacturer
Each mould is built by Jain Laboratory Instruments Pvt Ltd, the company that trades as JLab, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Laboratories buying from the factory can add moulds later and have them matched to those already in use, with base plates and reference pins quoted by the same maker. JLab exports worldwide, including to Fiji in Oceania, Botswana in Southern Africa, the UAE in the Middle East and Bhutan in South Asia.
