Graded sand is used as a concrete additive to enhance the properties and performance of the concrete mix.

Key Benefits of Lapis Gold Silica Sand:

  • Improved Particle Packing – Graded sand consists of a range of particle sizes, allowing better packing density and resulting in higher strength and reduced cement and water demand.
  • Workability Enhancement – Well-graded sand ensures a more workable and cohesive concrete mix, making it easier to pour and finish.
  • Durability and Strength – With better compaction and lower permeability, concrete made with graded sand is less prone to shrinkage and cracking.
  • Reduction of Bleeding and Segregation – A uniform gradation reduces the chances of water bleeding to the surface or aggregates settling out.
  • Consistency in Mix Design – Graded sand offers predictable performance, which is critical for producing consistent batches of concrete.

APPLICATIONS:

  • High-performance concrete
  • Precast concrete products
  • Structural concrete in buildings and bridges
  • Shotcrete and sprayed concrete
  • Grouting and repairing mortars
