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.
