The Effect of Alkaline Treatment on Mechanical Performance of Natural Fibers-reinforced Plaster: Optimization Using RSM

ABSTRACT

In the last decades, eco-friendly materials are playing an interesting role. Particularly, many studies deal with the use of natural fibers as a replacement to synthetic fibers in the plaster matrix. This study has examined the flexural properties of treated natural sisal, flax and jute fibers with different concentrations of NaOH (1.5%, 2% and 4%) and fiber length (5, 10 and 20 mm) reinforced plaster mortars. In this study, the effect of experimental parameters was determined by using analysis of variance ANOVA test. In addition, the response surface methodology (RSM) and desirability function (DF) are also used to optimize the output responses with maximizing the flexural properties. Finally, the experimental results are in good agreement with those obtained statistically.

摘要

在过去的几十年里，环保材料扮演着一个有趣的角色. 特别是，许多研究涉及到用天然纤维代替石膏基质中的合成纤维. 研究了不同NaOH浓度（1.5%、2%和4%）和纤维长度（5、10和20 mm）的天然剑麻纤维、亚麻纤维和黄麻纤维增强石膏砂浆的弯曲性能. 在本研究中，通过方差分析ANOVA检验来确定实验参数的影响. 此外，响应面法（RSM）和可取性函数（DF）也被用来优化输出响应，最大限度地提高弯曲性能. 实验结果与统计结果吻合较好.
