Durability and thermal properties of prepacked aggregate concrete reinforced with waste polypropylene fibers

The prepacked aggregates fiber-reinforced concrete (PAFRC) is an innovative type of concrete composites that recently has gained popularity and pulled the attention of researchers worldwide. The PAFRC components can be manufactured by initially placing the mixture of coarse aggregates with various s...
