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 prepacked aggregates fiber-reinforced concrete (PAFRC), which is a newly developed concrete, with a unique combination of coarse aggregate and short polypropylene (PP) fiber that is premixed and placed in the formworks. This study presents the outcomes of an investigational work that addresses creep and drying shrinkage performance in addition to the strength development of PAFRC specimens. In addition, palm oil fuel ash (POFA) was used at the substitution level of 20%. Six mixes comprising fiber volume fractions of 0–1.25% with a length of 30 mm were cast by gravity technique. Another six mixtures with the same fiber volume fractions were cast using a pump to inject the grout into the formwork. The experimental outcomes exposed that utilization of waste PP fibers and POFA improved the compressive strength of PAFRC mixes. The drying shrinkage and creep of PAFRC mixes reduced significantly with the addition of waste PP fibers. Moreover, due to the lower drying shrinkage and creep, as well as the unique production technique, PAFRC could be used for several innovative applications in construction.

预包装的骨料混凝土（PAC）是一种特殊形式的混凝土，其通过将不同尺寸的骨料放置并包装在模板中来制造，然后通过注入高流动性的水泥浆来填充骨料之间的空间。这项研究提出了一种预包装的骨料纤维增强混凝土（PAFRC），这是一种新开发的混凝土，具有粗骨料和短聚丙烯（PP）纤维的独特组合，可以将其预混合并放置在模板中。这项研究提出了一项研究工作的成果，该研究工作除了解决PAFRC标本的强度发展问题外，还解决了蠕变和干燥收缩性能。此外，棕榈油燃料灰分（POFA）的替代水平为20％。六种混合物，纤维体积分数为0-1。25％的长度为30毫米，采用重力技术铸造。使用泵浇铸另外六种具有相同纤维体积分数的混合物，以将水泥浆注入模板。实验结果表明，利用废PP纤维和POFA可以提高PAFRC混合物的抗压强度。通过添加废PP纤维，可以显着降低PAFRC混合物的干燥收缩率和蠕变。此外，由于较低的干燥收缩率和蠕变以及独特的生产技术，PAFRC可用于建筑中的多种创新应用。通过添加废PP纤维，可以显着降低PAFRC混合物的干燥收缩率和蠕变。此外，由于较低的干燥收缩率和蠕变以及独特的生产技术，PAFRC可用于建筑中的多种创新应用。通过添加废PP纤维，可以显着降低PAFRC混合物的干燥收缩率和蠕变。此外，由于较低的干燥收缩率和蠕变以及独特的生产技术，PAFRC可用于建筑中的多种创新应用。
