Sandblasting Grit
Afrigrit abrasives conform to national and
international health and safety regulations and
is non-toxic and inert.
Like garnet, AFRIGRIT has a high resistance to shattering on impact
which results in low dust operations compared to other expendable
abrasives.

Aggregates
Slag is a constant by-product of the metallurgical
industry, which has been treated, recycled and used
worldwide. The metallurgical oxide slags have stone-
like properties and thus, their major applications are in
the civil engineering field. Due to the high cost of
natural material and the rising emphasis on
sustainable construction, the construction industry
uses our aggreagtes as a viable alternative.
In concrete, the slag or natural aggregate makes up 70% of the concrete volume, and is
one of the main constituent materials in concrete production.
Typical applications
•
Road pavement layers: subbase -, selected-, and fill layers.
•
Mechanical modification and chemical stabilisation.
•
Concrete aggregate/seal aggregates/asphalt aggregate/slurry aggregate/ subsiol aggregate.
•
Gravel roads, improving the strength of gravel roads (less maintenance).
•
Strengthening of haul roads (less maintenance).
•
Run off dump slag for fill applications.
•
Bedding material and backfill for stormwater pipes.
•
Rehabilitation of mining areas.
•
Wash/parking bays.
•
Electrical KVA yards.
•
Stemming material to insulate an explosive charge.
•
Manufacturing of paving, and building bricks.
•
Preamble reactive barrier to remove contaminants from water.
•
Increase soil texture by breaking down clay-like soil.

Mineral Separation
Our process design is based on accomplishments
realised and lessons learned from the many plants
built in the past.
Utilising our vast process development, design and
project engineering capability combined with extensive
operating experience, our plants ensure optimum
capital and operating costs for high recovery.
Crushing, screening, slimes handling and
water reticulation form part of the process,
and all by-products of the process are
managed in an environmentally safe fashion.

Historic overview of slag in road building
The first appearance of slag was recorded as early as
the year 700B.C.
It can also be concluded that the history of slag is as
old as the melting process in which it was generated.
The first modern roads in which slag was utilised,
were built in England in 1813. As early as 15 years,
after good experiences with the application of this
material in road building were confirmed, slag
started to be used in railway construction as well.
Since then, blocks obtained by casting of slag have
been massively applied in Europe/America for road
pavements.
The use and advantages of slag in road building:
•
Sharp edges, a proper grain shape, and rough surface texture also contribute to better adhesiveness of aggregates
binder and grain, and increase the co-efficient of internal friction of bituminous overlay more than any other natural
aggregate.
•
Physical properties, in addition to proper granulometric composition, increase shear tightness of mixtures and
resistance to appearance of rutting.
•
Slag is harder and internally bound, natural gravel does not have the same stability and load bearing capacity.
•
Due to slag being harder and more compact that natural rock, roads last longer with less wear.
•
In contrast, natural rock becomes smooth with wear and its surface becomes polished and slippery.
•
As a result, tyres can grip better on surfaces constructed using slag, and this is particularly important on highways
and in curves.
