Drying shrinkage and creep properties of prepacked aggregate concrete reinforced with waste polypropylene fibers

Prepacked aggregate concrete (PAC) is a particular form of concrete that is manufactured by placing and packing aggregates with different sizes in a formwork, and the spaces between the aggregates are then filled through the injection of cement grout with high flowability. This study proposed the pr...
