Single Cover Concrete Spacer – 40mm Cover – 300pk

Description

Single Cover Concrete Spacer 40mm Cover – 300pk (6192-CSAS40) is a cement-based spacer that holds reinforcing steel 40mm from the formwork. Each pack holds 300 spacers.

The spacer is made from a mix of OPC, GBS, GGBS, fibres and additives. The manufacturer’s data sheet lists compressive strength not less than M60, water absorption under 5% and deflection under load under 1mm.

The same data sheet lists a very low rapid chloride penetration result, chloride content under 0.3 kg/m3 and alkali silica reactivity as harmless. A pack weighs 25kg.

Reinforcing fixers and concreters use the single cover spacer, also called a concrete spacer or cover block, to set 40mm cover on commercial, industrial and civil pours.
