The term 'Thin Shell Concrete' applies to components having a section of 50mm or less.

The material is, in effect, a form of ordinary concrete in which the ingredients are proportionally scaled down. The reinforcement is in the form of fine steel mesh and/or small diameter steel bars. The matrix is a cement mortar formulated with natural aggregates which is placed and consolidated in moulds under pressure to form a dense, strong material. The shell is usually stiffened by ribs made from the same matrix shell.

This fabrication technique produces a material with a special combination of attributes which provide an opportunity to extend the versatility of traditional concrete.

More specifically, CON-TECH Thin Shell:

• Is a high density material with good impact resistance and a compressive strength in excess of 40N/mm2
• Permits the combination of architectural and structural requirements in the same member.
• Allows the production of elements in section thickness as low as 15mm and thus offers a cost-effective alternative to GRC or GRP materials.
• Facilitates the production of complex shapes of thin section which can provide architects and engineers with the opportunity to reduce the dead weight of the element.
• Is available in a variety of finishes and surface textures to suit individual requirements.
