Sponsored by Lafarge South
Africa’s Readymix concrete divi-
sion, and Chryso South Africa
in collaboration with global
pigment producer Lanxess of Germany
(for which local distribution is exclu-
visely handled by Chryso SA), the Lafarge
Artevia awards were introduced in 2009
to show how decorative concretes can
create better, more durable structures
and enhance the environment in which
they are located. Chryso South Africa has
for many years supplied a variety of prod-
ucts that form part of the mix for Lafarge’s
acclaimed Artevia range.
As part of the Lafarge Artevia concrete
mix for House Bozwana, Chryso supplied
a specially formulated Lanxess Bayferrox
Sandstone pigment to colour the concrete
in selected areas; as well as other Chryso
products such as Chryso Fluid Optima 100,
Chryso Fibre Plus, Chryso Deco Lav PO5,
and Chryso Deco Mat.
Admixture Chryso Fluid Optima 100 is
a ‘new generation’ super-plasticiser which
substantially extends concrete worka-
bility and is compatible with most types
of cement. It provides the solution when-
ever there is a problem of compatibility
between the cement and the additive, and
is particularly suitable for the readymix
industry and construction sites.
Chryso Fibre Plus is a high perfor-
mance product that controls cracks and
prevents bleeding while also enhancing
the fire rating of concrete. Safe and envi-
ronmentally friendly, Chryso Deco Lav
PO5 – which can be used with different
types of aggregates from different regions
– economically improves the definition
of exterior forms and improves the tech-
nical quality and durability of structures.
Chryso Deco Mat is an acclaimed surface
protector for concrete and mortar.
Johannesburg-basedOcean Side Trad-
ing were the installers and polishers of
House Bozwana and won the overall top
award of R40 000. Nico van der Meulen
Architects, were also among the profes-
sionals honoured at a gala function
at the Michelangelo Hotel in Sandton.
The judges were Paragon Architects’
Hugh Fraser; Lafarge Artevia’s Anathi Zitu-
mane; and Chryso SA’s Kirsten Kelly. They
found that House Bozwana was exceptional
in that it “showcased various finishes of
decorative concrete: polished finishes to
create a stylish impact for the entrance, stairs
and entertainment areas; exposed finishes
to provide low maintenance and gravel-tex-
ture appearance in the driveway; while on
the stairs and entrance areas, the beautiful
Artevia finishes were set off to stunning
effect through the use of natural, off-shutter
Lafarge Agilia, combined with steel”.
Other category winners in the 2013
Lafarge Artevia awards included QS Concrete
Grinding and Polishing (Polishing Award),
Horticare (Exposed), Melt Wahl (Colour),
Boogertman & Partners (Exposed), and
Panmixers SA (special award for showcasing
Lafarge Artevia decorative concrete in the
company’s showroom).
Commenting on the merits of deco-
rative concrete in the design field, award-
winning House Bozwana architect, Nico
van der Meulen, said the concept has great
potential in SA but called for skilled and
experienced applicators capable of achieving
the desired standard. “The standard of the
applicators’ workmanship and skills ulti-
mately determine the quality of the finished
product,” he added.
