Abstract

This investigation utilized the combined blend of basalt and bamboo fibers as an additive in concrete, with the fibers being added based on the weight of the cement. The performances of concrete on the aforementioned fibers were compared based on mechanical parameters. The specimens were matured for 7, 28, and 90 days. It was observed that the inclusion of BFBM (basalt fiber and bamboo fiber) into HFRC (Hybrid fiber-reinforced concrete) resulted in a 17.11% increase in compressive strength (CS) after 28 days of maturing when the BFBM dose was 2.0%. Utilizing BFBM to analyze the flexural strength (FS) parameter led to a significant enhancement in FS. At a dosage of 1.5%, the FS increased by 100% after 7 days of curing, while at a dosage of 2% after 28 days of maturing, the FS increased by 52.98% compared to concrete. The UPV Test verified the presence of a uniform concrete mixture. Examination of data using SPSS software was done to perform regression analysis, factor analysis, and principal component analysis. The regression analysis revealed statistically significant associations between the dosage, maturing age, and mechanical characteristics of concrete. The factor analysis showed an efficient consolidation of the three variables into a single component, which accounted for 88.08% of the variation. The Kaiser-Meyer-Olkin (KMO) measure validated the sufficiency of the sample, whereas Bartlett’s test revealed the presence of sphericity. The results indicate that the dosage amount and the length of time for curing have compelling impact on the strength qualities of the concrete.

使用玄武岩和竹子组合纤维的水泥混凝土的力学性能

这项研究利用玄武岩纤维和竹纤维的混合物作为混凝土添加剂，纤维的添加量以水泥重量为基础。根据力学参数比较了使用上述纤维的混凝土的性能。试样的成熟期分别为 7 天、28 天和 90 天。结果表明，在混合纤维增强混凝土（HFRC）中加入 BFBM（玄武岩纤维和竹纤维）后，当 BFBM 的剂量为 2.0% 时，28 天成熟后的抗压强度（CS）提高了 17.11%。利用 BFBM 分析抗折强度（FS）参数可显著提高 FS。用量为 1.5% 时，养护 7 天后 FS 增加了 100%；用量为 2% 时，养护 28 天后 FS 比混凝土增加了 52.98%。UPV 试验验证了混凝土混合物的均匀性。使用 SPSS 软件对数据进行了回归分析、因子分析和主成分分析。回归分析表明，混凝土的用量、龄期和力学特性之间存在显著的统计学关联。因子分析显示，三个变量被有效地合并为一个成分，该成分占变异的 88.08%。凯泽-迈耶-奥尔金（KMO）测量验证了样本的充分性，而巴特利特检验则表明存在球形性。结果表明，用量和养护时间的长短对混凝土的强度质量有显著影响。

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
