A cast-iron cube mould 150 × 150 × 150 mm, IS 10086 certified — the standard specimen mould for concrete compressive-strength testing per IS 516 and IS 456. Multi Trade Combines stocks certified moulds in Guwahati for Northeast India contractors and civil labs; price on request.
The 150 mm cast-iron cube mould is the fundamental specimen-casting tool in every concrete quality-control programme across India. It is the vessel into which fresh concrete is sampled and compacted from the site batch, cured in a water tank for the specified period, then loaded to failure in a compression testing machine to determine the characteristic compressive strength of the concrete — the critical acceptance criterion under IS 456. Multi Trade Combines in Guwahati stocks IS 10086-certified 150 × 150 × 150 mm cube moulds for civil laboratories, site QC teams and government quality-control offices across Northeast India.
The cast-iron construction provides the rigid, dimensionally stable mould that IS 10086 demands. All four side-plate faces and the base plate are machined to close flatness and squareness tolerances, ensuring the cast cube has true parallel faces that contact the compression platen uniformly during the crushing test. Poorly made moulds produce non-parallel cube faces that create eccentric loading in the testing machine, resulting in low and non-representative strength readings — a risk particularly relevant on government-supervised infrastructure projects where cube results are contractually binding.
In Northeast India, cube testing is a contractual requirement on every PMGSY, NHIDCL, BRO and state PWD civil works contract. Contractors operating on multi-site road and bridge projects in Assam, Meghalaya, Nagaland, Arunachal Pradesh and Manipur maintain field laboratories stocked with IS 10086 cube moulds. Urban housing projects under PMAY and Smart Cities Mission in Guwahati and Shillong use cube test results as the primary concrete-quality record. We supply cube moulds in single units and in bulk sets to contractors, testing laboratories and engineering institutions throughout the region.

Civil contractors on every government-supervised construction project in the Northeast are required to submit cube test results to the Engineer-in-Charge under IS 456 acceptance criteria. Site engineers and quality-control supervisors on NHIDCL and NHAI highway projects, BRO mountain road sites, and PMGSY rural road contracts all use 150 mm cube moulds daily during concrete pours. Third-party quality-inspection agencies appointed by state governments to monitor infrastructure quality also operate mobile cube-testing setups that require IS 10086 moulds. Engineering colleges and polytechnics in Assam, Meghalaya and Manipur maintain concrete-testing labs stocked with cube moulds for materials science practicals. Ready-mix concrete (RMC) plants in Guwahati carry out routine cube testing of each production batch. Multi Trade Combines has supplied civil lab equipment to the NE construction sector since 1993.
Cube moulds are always used alongside a tamping rod (16 mm diameter, 60 cm long, bullet-ended, as specified in IS 516) for manual compaction of the fresh concrete specimen. A concrete vibrator (needle vibrator) is used for vibrated specimens. Cube moulds need a flat, vibration-free casting platform and a properly maintained water-curing tank at 27±2°C for the 28-day curing period. After demoulding, the cubes go to a compression testing machine (CTM) for strength determination. Multi Trade Combines stocks tamping rods, vibrating tables and related civil-lab consumables alongside our cube mould range.
IS 516 (Method of Tests for Strength of Concrete) specifies a 150 × 150 × 150 mm cube mould as the standard test specimen for compressive strength determination in India. The mould must conform to IS 10086, which governs the tolerances on dimensions, flatness and the assembly of the base plate. Multi Trade Combines stocks IS 10086-certified 150 mm cast-iron cube moulds in Guwahati, suitable for concrete testing as per BIS and PWD standards across Northeast India.
IS 456 requires a minimum of three cubes from each batch of concrete, cured and tested at 7 days and 28 days. A typical site laboratory handling multiple pours per day needs at least 6 to 12 cube moulds in circulation — some filled and curing, some at the testing lab, and some cleaned and ready for the next pour. For large projects, 12–24 moulds is a practical working set. Call +91 91812 13332 for quantity pricing from Multi Trade Combines, Guwahati.
