Reduced W/C ratios and the usage of silica fume make concrete mixes significantly less workable, which is especially more likely to be a challenge in significant-toughness concrete apps where by dense rebar cages are very likely to be used. To compensate for your diminished workability, superplasticizers are commonly additional to substantial-toughness mixtures.

After the concrete continues to be poured and allowed to set, the anchors are unveiled and, given that the metal seeks to return to its initial duration, it compresses the concrete. Within the posttensioning process, the steel is operate by way of ducts fashioned in the concrete. In the event the concrete has hardened, the steel is anchored to the exterior with the member by some kind of gripping gadget.
