Tata Aggreto

Tata Aggreto by IBMD can be used as a replacement of natural aggregates

In January 2018, Tata Steel became the first company in the country to launch branded LD slag product, Tata Aggreto, which can be used as a replacement of natural aggregates.

Our brand promise is to provide superior, ready-to-use material with consistent sizes.

How is Tata Aggreto made?

LD Slag undergoes crushing and screening into different size fractions measuring up to 65mm with sub-fractions <6 mm, 10-20mm, 20-40mm and 40-65mm. Sub-fractions 10-20 mm, 20-40 mm & 40-65 mm LD Slag are weathered to limit the volume expansion due to presence of free lime within 2%. The water used for weathering is obtained from rain water harvesting. The completion of ageing is established through a Volume Expansion Test. The final products after weathering & passing through the volume expansion test in sizes 10-20 mm, 20-40 mm & 40-65 mm are Tata Aggreto.

Tata Aggreto, which is used as a replacement of natural aggregates, are verified through a number of tests such as Grain Size Distribution, Resistance to Crushing and Abrasion Test. After passing the stringent quality parameters, our slag is offered to the customers.

Applications

Tata Aggreto is an ideal material used as a replacement of natural aggregates in all the layers of road making such as Subgrade, Sub-base layer, Base Layer and Bituminous Layers.
