In pre-tensioned concrete, the prestressing is obtained by making use of metal or polymer tendons or bars that happen to be subjected into a tensile pressure before casting, or for article-tensioned concrete, right after casting.
Other finishes may be accomplished with chiseling, or even more regular approaches for instance painting or masking it with other materials.
Forbes Household adheres to rigorous editorial integrity criteria. To the very best of our expertise, all information is exact as with the date posted, even though delivers contained herein could no more be offered.
Pre-tensioning course of action Pre-tensioned concrete is usually a variant of prestressed concrete where by the tendons are tensioned ahead of the concrete becoming Forged.
In fashionable usage, most concrete output can take location in a large style of industrial facility referred to as a concrete plant, or often a batch plant. The same old approach to placement is casting in formwork, which retains the combination in shape right until it has set ample to carry its form unaided.
The terms asphalt (or asphaltic) concrete, bituminous asphalt concrete, and bituminous mixture are typically employed only in engineering and development files, which determine concrete as any composite materials composed of mineral mixture adhered by using a binder.
