Abstract

The utilization of innovative, lightweight, durable, and ecologically friendly polymer concrete is becoming more popular. Therefore, this research was conducted to investigate the mechanical performance of polymer concrete produced using Vinyl Ester (VE) resin and high-volume Fly Ash (FA) filler with a focus on compressive, tensile, and flexural strength of strong and weak axes using a three-point flexural test. It is important to note that the resin varied from 20 to 90%, FA from 10 to 20%, Mepoxe (MK) catalyst was 4.5%, and Cobalt (Co) was 1% of resin volume. Moreover, cube specimens were used to determine compressive strength and specific gravity at 3 days, cylindrical specimens were also used to determine compressive strength at the age of 1 and 2 days, and dog-bone-shaped specimens were used for tensile strength. This research also applied a three-point flexural test to both the strong and weak axes of the specimens. The result showed that the specimen with 30% VE and 70% FA (RUN-3) had the most effective compressive strength, specific gravity, price, and casting simplicity or workability as by the 66,2 MPa recorded for compressive strength and 1.88 gr/cm3 for specific gravity with two stages of elastic and plastic failures. The RUN-3 mixture was also used to produce cylindrical specimens and tensile strength was found to be 11.55 MPa while flexural strength in the transverse and lateral axis was 53.74 MPa, and 57.69 MPa respectively.

抗拉、抗压和抗弯荷载下掺入大体积粉煤灰的乙烯基酯基聚合物混凝土
创新、轻质、耐用和生态友好型聚合物混凝土的使用正变得越来越流行。因此,本研究对使用乙烯基酯(VE)树脂和高容量粉煤灰(FA)填料生产的聚合物混凝土的力学性能进行了调查,重点是使用三点抗弯试验检测强轴和弱轴的抗压、抗拉和抗弯强度。值得注意的是,树脂含量从 20% 到 90%不等,FA 含量从 10% 到 20%不等,Mepoxe(MK)催化剂含量为 4.5%,钴(Co)含量为树脂体积的 1%。此外,立方体试样用于测定 3 天时的抗压强度和比重,圆柱形试样用于测定 1 天和 2 天时的抗压强度,狗骨形试样用于测定抗拉强度。这项研究还对试样的强轴和弱轴进行了三点弯曲试验。结果表明,含 30% VE 和 70% FA 的试样(RUN-3)具有最有效的抗压强度、比重、价格和浇注简易性或可加工性,抗压强度为 66.2 兆帕,比重为 1.88 克/立方厘米,分为弹性和塑性破坏两个阶段。RUN-3 混合物还用于制作圆柱形试样,结果发现拉伸强度为 11.55 兆帕,横向和侧向轴的抗弯强度分别为 53.74 兆帕和 57.69 兆帕。
