Impact loading on concrete slabs

with a clear correlation to the height All slabs subjected to impact load showed a one-way flexural failure, the residual strength after impact was sufficient to carry the static load of the steel weight Several of the slabs showed significant fallout of concrete during impact, in one extreme case a total of 16 kg Three slabs were tested with an...

Creep and shrinkage of concrete

Creep and shrinkage of concrete are two physical properties of concreteThe 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 Unlike the creep of metals, it occurs at all stress levels and, within the service stress ....

Insulated Concrete Forms

Insulated Concrete Forms Energy Performance & R-Valu Fact or Fiction: "The R-value tells me how much energy my house will use, right?" R-value measures the resistance a material has to heat transfer, this much is true R-value alone, however, does not fully describe the energy performance of a building...
