IS 1199 galvanised mild steel slump cone with tamping rod and base plate — for fresh concrete workability testing on construction sites and in concrete technology labs across Northeast India. In stock at Multi Trade Combines, Guwahati.
The slump cone is one of the most fundamental and widely used pieces of concrete quality testing equipment on construction sites and in concrete technology laboratories across India. Every batch of concrete mixed for a structural element should be tested for workability before placement — a concrete mix that is too dry will not consolidate properly under vibration, leaving voids in columns and beams; a mix that is too wet will segregate and produce a weak, porous structure. The slump cone test gives the site engineer a fast, practical workability measurement in under two minutes, enabling immediate adjustment of the mix before placement rather than discovering a problem after the pour has hardened.
The IS 1199 slump cone is a truncated steel cone with internal dimensions of 200 mm base, 100 mm top and 300 mm height — these dimensions are precisely defined in the standard and must be maintained for the test result to be comparable between tests and laboratories. Galvanised mild steel is specified because it maintains these dimensions over years of site use without rust distortion, and can be cleaned quickly between tests. Multi Trade Combines supplies IS 1199 slump cones with tamping rod and base plate to construction site quality labs, concrete batching plant QC teams and engineering college concrete technology laboratories across Northeast India from our AT Road, Guwahati counter.

All structural concrete specifications for buildings, bridges, roads and dams in India — whether under IS 456 (reinforced concrete), IRC 112 (concrete bridges) or MoRTH specifications (road structures) — specify a slump range appropriate to the structural element and placement method. Pumped concrete needs a higher slump (100–150 mm) to flow through the pump line; mass concrete for dam gravity blocks uses very low slump (25–50 mm) to control heat generation. The slump cone is the tool that confirms the batch is within specification at the point of delivery, before the concrete is placed and the opportunity to correct it is lost.
Guwahati's rapid urban construction — high-rise residential towers, commercial complexes, flyovers and the expanding metro infrastructure — involves large volumes of ready-mix concrete delivered from batching plants to site. Concrete pump operators and site engineers must slump-test every truck load on arrival under IS 456 quality requirements. Engineering colleges in Assam, Meghalaya, Nagaland and Manipur teaching concrete technology practicals use IS 1199 slump cones as standard laboratory equipment. Multi Trade Combines is the in-stock supplier for the full concrete testing equipment set — slump cone, cube moulds, compression testing machine and vibrating table — available from our Guwahati counter.

The slump cone test (IS 1199) is the most widely used method to measure the workability (consistency) of fresh concrete. A standardised steel cone is filled with concrete in three layers, each rodded 25 times with a steel tamping rod, and then lifted vertically. The concrete slumps — subsides — under its own weight and the reduction in height from the cone's 300 mm to the final height of the concrete is the slump value in millimetres. This slump value tells the engineer whether the concrete mix is too stiff (low slump), within the specified range, or too wet (high slump) for the intended structural application.

The slump cone follows IS 1199, which specifies the cone dimensions: base diameter 200 mm, top diameter 100 mm, and height 300 mm. Galvanised mild steel is the standard construction material — galvanising prevents rust staining of the concrete sample which can affect colour-based quality checks and prevents the cone from corroding and losing dimensional accuracy over time. Stainless steel cones are also available for laboratories requiring longer service life and easier cleaning. WhatsApp +91 76359 98826 for stock confirmation.
