Specifications

SepROAD is a CEM II B-L 32,5N class cement, formulated to comply with South African National Standard SANS 50197-1:2013 cement specification for common cements. Specifically formulated to stabilise a broad range of road materials, SepROAD is formulated using intimately ground clinker and high quality limestone, reducing Plastic Index (PI) and unconfined compressive strength (UCS) of high clay soils, ensuring durability, stability and strength. The longer setting times make it ideal to stabilise longer stretches of road.

In soil stabilisation the objective is to thoroughly and intimately mix a carefully selected crushed soil and a stabilising agent, SepROAD, with an Optimum Moisture Content as tested in a laboratory to achieve the highest compacted density and therefore the best Unconfined Compressive Strength, and achieve the best durability for your stabilised road subbase to receive the final wearing surface.

Benefits

  • Ideal formulation for modification of different soil types.
  • Extremely versatile for a wide range of building and civil applications.
  • Ideal to do longer stretches of stabilisation on roads.
  • Due to longer setting times when used for stabilisation, gives better UCS strengths.
  • Ease of use by spraying or bags.
