BST Lightweight Concrete Aggregate is made from small polystyrene balls and granulate, treated in a special production method, and coated with a proprietary, non toxic coating.  The coating is activated when in contact with the wet, cementitious materials, enabling the BST Aggregate to disperse evenly throughout the concrete.  This is essential to ensure that the strength and other concrete properties are uniform throughout the concrete.

BST Concrete is widely used for floor and roof toppings, as well as in many civil and product applications.  The advantages of BST Concrete include:

• light weight and strong – provides cost effective design solutions where weight is a consideration
• excellent fire resistance
• thermal and acoustic insulation
• low water permeability
• flexibility
• easy to pump and place

  

BST Aggregate is an Australian product, developed in conjunction with the University of Technology, Sydney.
