Splet05. mar. 2024 · Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers. Splet09. feb. 2024 · Drying shrinkage is essentially a function of the ambient humidity and of the notional size ho = 2Ac/u. Clause [3.i.4 (6)-EC2] gives formulae and tabled values normally used.
