Experimental Study on a Prediction Model of the Shrinkage and Creep of Recycled Aggregate Concrete

Applied Sciences, 2019
The significant difference between recycled aggregate and natural aggregate is the content of the attached mortar layer. With the increase of the replacement rate of recycled aggregate, the shrinkage and creep of recycled aggregate concrete is ...
