After treating, the subsequent lower temperature levels cause the plastic to agreement, and a space remains at the user interface between the plastic and concrete. Plastic spacers are also subject to rust when they enter into contact with chlorides and chemicals, where concrete has a much greater resistance. Concrete spacers and bar assistances are made from the exact same material as the poured concrete, so thermal expansion and contraction are equal.

No spaces! Concrete spacers and bar supports help preserve material integrity and harmony of the concrete, and offer a cover over the support that secures against rust. What about concrete spacers with a plastic clip or repairing system? Does the plastic clip or fixing system in the concrete spacer have a negative impact on product integrity? Does it damage the rust protective cover over the support? The answer is no! The plastic clip or fixing system is hinged from the top of the spacer and does not enter contact with the soffit of the concrete.

The plastic in the clip or fixing mechanism is used just for easily attaching to and holding the reinforcement, leaving the concrete part to do the work of the spacer. Bear in mind that not only do plastic spacers provide no compatibility with the materials used in civil engineering structures, but can hold only a fraction of the weight a concrete spacer can, therefore you should utilize more plastic spacers to cover the very same amount of reinforcement (the ratio is typically 1 to 2, but will increase if the weight of the rebar structure is increased, ratios of as much as 3 to 1 have actually been observed), so there may be no real value either financial or technical added when plastic spacers are used.

Guide to select and use the concrete spacer in strengthened concrete structures. Although the spacers have the comparable features, however the selection of the righ type will assist in the building and make it more efficient. Reference of spacer will base upon the following elements: The small height of spacer is the dimensions of the spacer to form the specific concrete cover for the steel rebar in concrete.
