be a real differentiator in the CPM market.
Top of the range 52.5R Rapid Hard Cement,
developed for specialist concrete product
manufacturers, is performing particularly
well, achieving in excess of the SANS 50197
minimum of 30 MPa mortar strength at the
two day mark,” he says.
This is enabling CPMs to develop a
variety of new high specification products,
such as highway barriers, roof tiles, retaining
wall systems, culverts and concrete pipes.
AfriSam is the only company to manu-
facture 52.5R Rapid Hard Cement as a
standard product.
Choosing the correct specification and high
quality raw material can significantly impact
on the efficiency of CPMs.
By using AfriSam cement, CPMs
have reduced their cement
consumption, while achieving better
finishes and durability of their
concrete products.
AfriSam offers CPMs an Efficiency Audit
which is used to assess and evaluate the
operating process at the individual CPM, and
based on this the company is able to make
informed recommendations.
Its 42.5R High Strength Cement has been
specially formulated and activated to allow
for further extension with additional mineral
components in the production of structural
concrete. The “R” rating of the High Strength
Cement is supported by AfriSam’s strict
quality control plan and this product is
achieving in excess of the SANS 50197
minimum of 20 MPa mortar strength at the
two day mark.
AfriSam High Strength Cement is
commonly used to achieve concrete
strengths of between 10 and 50 MPa, but it
is also suitable for high strength concrete,
with strengths of 80 MPa and higher.
By using this AfriSam cement,
CPMs have also reduced their cement
consumption, while achieving better
finishes and durability traits of their
concrete products.
Importantly, AfriSam’s SANAS-accredited
laboratory services are also available to
verify and test the efficiency of mixes,
and product deliveries can be specifically
scheduled around customers’ individual
activities. “AfriSam is committed to the
CPMs sector and with our expertise at the
core we believe it will continue to grow
as developers, architects and con-
tractors see the gains achieved by
using precast concrete systems,”
Dawneerangen concludes.
AfriSam’s Centre of Product
Excellence has the necessary depth of
experience and skilled technologists
who understand concrete product
manufacturing processes.
