Title:

Paving Blocks from Fly Ash, Blast Furnace Slag, Steel Slag, etc.

Value Proposition:

Manufacture of paving blocks from industrial waste.

Summary Application:

The process produces pavement blocks of different shapes and sizes and different colours and designs. These paving blocks can be used in pavement, patio, lounge, garden, park, petrol pumps, etc and are suitable for light to medium load.

Advantages:
  • Meets IS 15658:2006 specification
  • Can be produced in different shapes and sizes with properties equivalent to Ml 5 - M35 grade concrete.
  • Uses ambient temperature synthesis and generates 30% less C02,35% low embodied energy than conventional equivalent product.
  • The product meets USEPA 1311 specification for toxicity. Also due to 35% low C02 emission and 35% less embodied energy, it falls in the category of green.
  • Due to use of waste and byproduct, it qualifies for 1 point in LEED certification for green building.
