Polymer concrete is a promising material with applications in construction and architecture; however, guidelines for its design and optimization are not well-established in the literature. This study aimed to evaluate how resin volume fraction and aggregate size distribution affect key properties of polyester polymer concrete, including flexural strength, compressive strength, water absorption, and material cost. Three types of quartz aggregates with different particle size distributions were used, as follows: small (below 0.5 mm, quartz dust), medium (0.2-2.0 mm, quartz sand), and large (2.0-10.0 mm, quartz gravel). The resin volume content varied from 5% to 30%. Differences in apparent density, open porosity, water absorption, flexural strength, compressive strength, and material cost were analyzed as functions of resin volume content and aggregate size. The results showed that apparent density and mechanical properties are positively correlated with resin content for small and medium aggregates; however, in the case of large aggregates, flexural strength decreased when the resin volume content exceeded 20%. A significant reduction in material porosity and water absorption (to ~0.4% and ~0.2%, respectively) was observed at high resin volume fractions.
聚合物混凝土是一种很有前景的材料，在建筑和建筑学领域有应用；然而，其设计和优化指南在文献中并未得到很好的确立。本研究旨在评估树脂体积分数和骨料粒径分布如何影响聚酯聚合物混凝土的关键性能，包括抗弯强度、抗压强度、吸水率和材料成本。使用了三种具有不同粒径分布的石英骨料，如下：小粒径（小于0.5毫米，石英粉）、中粒径（0.2 - 2.0毫米，石英砂）和大粒径（2.0 - 10.0毫米，石英砾石）。树脂体积含量从5%变化到30%。分析了表观密度、开孔孔隙率、吸水率、抗弯强度、抗压强度和材料成本的差异与树脂体积含量和骨料粒径的函数关系。结果表明，小粒径和中粒径骨料的表观密度和力学性能与树脂含量呈正相关；然而，对于大粒径骨料，当树脂体积含量超过20%时，抗弯强度下降。在高树脂体积分数下，观察到材料孔隙率和吸水率显著降低（分别降至约0.4%和约0.2%）。
