This can lead to improved structural potential or serviceability, or both of those, when compared with conventionally reinforced concrete in lots of scenarios.[six][2]: six In a prestressed here concrete member, The inner stresses are launched inside of a planned way so that the stresses resulting from the imposed masses are counteracted to the specified degree.
Encyclopaedia Britannica's editors oversee subject matter regions by which they have got extensive expertise, regardless of whether from years of expertise gained by working on that content or through review for a complicated diploma.
