Creep and shrinkage of recycled aggregate concrete ...

Jul 01, 2009  The main aim of this work was to determine creep and shrinkage variations experienced in recycled concrete, made by replacing the main fraction of the natural aggregate with a recycled aggregate coming from waste concrete and comparing it to a control concrete. The substitution percentages were 20%, 50% and 100%.

Shrinkage and Creep Performance of Recycled Aggregate Concrete

10%  Recycled aggregate concrete is not a new concept, but it is normally met with resistance due to reduction in strength and an increase in drying shrinkage. The organizations that allow for recycled concrete aggregates in concrete give few guidelines. One of the common requirements is that the recycled aggregates should be soaked prior to use.
