By using AfriSam cement, CPMs have reduced their cement consumption, while achieving better finishes and durability of their concrete products.

AfriSam’s Centre of Product Excellence has the necessary depth of experience and skilled technologists who understand concrete product manufacturing processes.

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

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. 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.

as developers, architects and con- tractors see the gains achieved by using precast concrete systems,” Dawneerangen concludes. 

Choosing the correct specification and high quality raw material can significantly impact on the efficiency of CPMs.
