BLOCKFAST AC 300 is polycarboxylate ether based concrete accelerator and is supplied as a light yellow      liquid. When added to cementitious mixes it accelerates hydration and enables the water content to perform more    efficiently by dispersing agglomerated cement particles. This further improves strength by enabling water   reduction to be made at constant workability.

  • Fast accelerating admixture for paver industries, precast industries and higher grade of concrete
  • High range accelerator for concrete works either reinforce or unreinforced
  • Glossy and smooth surface for precast product
  • Precast concrete work
  • Pre stress concrete work
  • All types of low and high rise buildings 

  • High range accelerating admixture for both the unreinforced and reinforced cement concrete and mortar
  • High range accelerating admixture for both the unreinforced and reinforce cement concrete or mortar
  • High range water reducer for concrete or mortar with increase in workability
  • Reduces segregation and increases compressive strength
  • Reduces porosity in concrete and increases durability
  • Early release from precast moulds rapidly increases production in industry
  • Produce super smooth and glossy surface
  • Reduces honeycomb in concrete structure
  • Produces a homogenous, cohesive concrete generally without any tendency for segregation and bleeding
