Granulate Mixer

Putman recycles its own recycled building material granulates into high-quality roadside concrete, stabilised foundation and immobilisation products. Putman can provide for customer-specific applications at any time in the desired quantity. 

By means of the granulate mixer certified in accordance with BRL1801 and BRL9338, Putman is able to supply road construction concrete products in the form of:

  • Stabilisation sand/Setting mortar
  • Loam concrete
  • High-quality road building concrete up to strength class C35/45 for i.a., cycle paths, roadside concrete and outrigger concrete

These products are produced with high recycling percentages and up to 70% CO2-saving types of cement, so that the products meet the sustainability requirements in the specifications of municipalities and provinces. Due to the great variability in available aggregates, additives and cement types, Putman is able to think along with the customer as much as possible about the mixture design.  We also use our granulates to produce concrete mortar for Putman Multiblocks. Putman Multiblocks are perfectly suited for a range of flexible, temporary and permanent applications, such as retaining walls and storage areas.

CO2 reductie and low EQI/MKI values because:
