Signo Aggreto undergoes crushing and screening into
different size fractions ranging from 0-65mm with
sub-fractions of 0-6mm, 6-20mm, 20-40mm and 40-65mm
used in combination for different layers of road.
Material is weathered (also called ageing) to limit the
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 an
expansion test. Other quality parameters are verifed through
a number of tests like grain size distribution, resistance to
crushing and abrasion test. After qualifying all the requisite
quality parameters, we declare our slag usable for offering to
our customers.
Processed steel slag is an ideal material for roads. It can be
used as a replacement of natural aggregates in all the layers
of road making vizs a vizs – Subgrade, Sub-base layer, Base
Layer & Bituminous Layers.
