摘 要:将稻草纤维掺入量定为0、2.5%、5%、7.5%、10%,并将稻草纤维分成丝状和粉末状,研究了不同形状、不同掺量的稻草纤维水泥基复合材料的力学性能。结果表明,随着丝状和粉末状纤维的加入,试件的抗压强度和抗折强度总体呈降低趋势,但抗冲击性能得到了明显的提升;随着稻草纤维掺量的增加,丝状水泥基复合材料的抗冲击性能增强会稳定在一个范围内,而粉末状水泥基复合材料的抗冲击性能会逐步增高并在掺量为10%时达到最佳。
Abstract: The fiber of rice straw incorporation is set as 0,2.5%,5%,7.5%,10%, the mechanical properties of different shapes and different amounts of rice straw fiber cement-based composite are studied. The results show that with adding filamentous fibers and powder fibers, the compressive strength and flexural strength of the cement base reduce gradually, but the impact performance has been significantly improved; and with the increase of dosage of straw fiber, the resistance of filamentous cement-based composite will be stable in a range, but the resistance of powder-like cement-based composite will gradually increase, and when the content of 10% achieves the best.
