Economically viable and sustainable replacement for the natural sand in concrete.
Where will you get yours from?
With sand that binds together with less voids in your mix to make stronger concrete with up to 20% less cement.
With sand that arrives at your site sized to specification and already blended to order, reducing the steps in your process.
Made from crusher dust, recycled glass and concrete to replace 100% of natural sand in your concrete and use less cement.
Ready mix. Precast. Asphalt
Roading. Pavements. Pipes. Slabs. Foundations.
Cuboidal shape to maximise the pumpability, workability and finishing characteristics of concrete.
Produce the right amount of each particle size to maximise the packing density in concrete, saving on cement and creating a nice creamy finish.
Clays, silts and other deleterious contamination extracted to reduce water content and avoid sand blending of final mix.
Precisely controlled process produces quality sand regardless of feed changes, for consistent and repeatable concrete performance.
Indications from a 20-day strength results are that replacement of standard PAP7 with Kayasand products can produce cementitious saving of at least 10% without compromising strength.
The improved strength performance of concrete made with Kayasand appears to be a combination of reduced water demand and improved packing, resulting in higher density.

Conserves natural resources. Decarbonises concrete. Made from crusher dust and re-cycled glass and concrete.
Engineered sand is a viable replacement for natural sand in concrete and significantly contributes to the industry hitting their carbon emissions targets by 2050.
