Index Engineering Co.

We are remarkable entity, engaged in offering superior range of Slump Cone Apparatus. 

Concrete slump test or slump cone test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work.

The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure. The slump test is used to ensure uniformity for different loads of concrete under field conditions.

The offered apparatus is provided in various specifications as per the needs of customers. We manufactured this apparatus using the latest techniques in accordance with the industry standards. Our offered apparatus is demanded in the market owing to their durability.
