Sprayed Concrete Accelerators

Sprayset HBL

Sprayset HBL is a chloride free liquid based on a blend of inorganic powders, which is added to a sprayed concrete mix to impart properties of high build and low rebound. Used to enable a high build of sprayed concrete, shotcrete and gunite without slump and provide set acceleration and reduce rebound.

• High build enables faster coverage with minimised slump.
• Can be applied up to 300mm in one application to vertical surfaces and up to 200mm overhead dependant on weight / volume of aggregate
• Non caustic leads to safer handling / operating conditions
• Low rebound - controlled set allows new material to be embedded in applied concrete mixture.
  
• Chloride free liquid
• 28 days strength not adversely affected
