Concrete, the world’s most widely used building material, has a proven track record of long-term performance in the development of infrastructure, commerce and many modern conveniences in today’s built environment.
Integrating higher quality materials, design and construction methods also minimises maintenance, repair and replacement costs, and inconveniences to commuters and businesses. This ensures wise stewardship of today’s investments for tomorrow’s generations, creating a safer, more sustainable built environment.
All SARMA members comply with strict standards of production and quality both in their products as well as their machinery must be maintained to a high standard.
We are the first Volumetric Concrete Company in South Africa to obtain this accreditation and with an outstanding 5 Star accreditation.
Eliminates Water of convenience from migrating to the surface
This prevents voids and capillary channels common within OPC placements that lead to shrinkage cracking, contamination and deterioration.
Eliminates Curling and warping of concrete placements
Preventing these common occurrences reduces corner breaks and impact spalls that occur when exposed to in-service traffic, and associated repair and maintenance costs.
Rapid Set. Cement provides the highest resistance to sulfate attack. Unlike OPC, Rapid Set. Cement contains no tri-calcium aluminate (C3A) compounds. Because it is the C3A that attacks sulfates, Rapid Set Cement minimizes the potential for sulfate attack by eliminating C3A altogether.
Rapid Set materials are highly compatible with Portland cement- based materials, and create a strong bond that eliminates “shrink back” at patch or repair perimeters, and prevents de-bonding.
Maintains Design Strength
Maintains design strength throughout the concrete/concrete repair placement by eliminating a detrimental change in w/c ratio at the surface. This results in higher impact, abrasion and spall resistance
Freeze/ Thaw Resistance
Rapid Set Cement’s low permeability is resistant to freezing and thawing exposures. Its rapid hydration and strength gain allow it to be used in cold weather installations that are not possible with OPC mix designs.
Rapid Set Cement excels in key performance criteria including: advanced material properties, installation efficiencies, application versatility, and sustainability. Rapid Set. is not ordinary portland cement mixed with admixtures, nor is it an accelerator. And, it is not a calcium aluminate cement prone to strength regression. It is an innovative, proven belitic calcium sulfoaluminate (bCSA) advanced cement technology used worldwide on projects where time, money and long-term durability are essential.
