Post date: 01-12-2016
Spacers help maintain proper cover to the reinforcement bars. Proper cover is essential as:
Depend on the type of structures, especially with the contact conditions of RC structures with ambient environment, the concrete cover must have the varied thickness. The more serious contact condition is, the thicker concrete cover must be applied.
The concrete cover thickness are usually regulated in the standards and fixed in each type of structures and conditions. Therefore, using the ready-manufactured spacers brings the advantages:
