摘要/Abstract

摘要： 普通水泥砂浆掺入由废弃木材制成的再生木纤维,会对其水化特性、力学性能及耐久性能产生不良影响,这限制了再生木纤维水泥基材料的推广与应用。本文以高贝利特水泥(HBSC)作为胶凝材料,将废弃木材经破碎、细化和打浆处理后获得再生木纤维,在成型压力50.0 kN条件下制备出轻质、高韧性HBSC砂浆,并对不同水灰比条件下砂浆各项性能进行研究。结果表明,较低的水灰比对提高轻质高韧性HBSC砂浆性能具有积极作用。随着灰木比从0.8增加至3.0,再生木纤维HBSC砂浆的干密度增大,最高为1 408 kg/m³。砂浆的抗压、抗折强度和收缩率均随之增加,砂浆28 d抗压强度由15.7 MPa增加至32.4 MPa,28 d抗折强度由6.3 MPa增加至12.2 MPa,不同水灰比下砂浆28 d最大收缩率均低于40.0×10^-5,导热系数为0.317 6 W/(m·K), 再生木纤维HBSC砂浆的轻质、高韧性和保温效果显著。微观测试结果表明,当灰木比为3.0时,砂浆的水化反应最充分,内部孔隙结构最密实。本研究为再生木纤维在轻质高强、高韧性的保温墙体材料中的应用提供参考依据。

Abstract: Incorporating recycled wood fibers made from waste wood into ordinary Portland cement mortar adversely affects its hydration characteristics, mechanical properties and durability, thereby limiting the promotion and application of cement-based materials containing recycled wood fibers. In this study, using high belite cement (HBSC) as cementation material, recycled wood fiber was obtained from waste board after crushing, refining and beating treatment, and lightweight and high-toughness high belite cement mortar was prepared under forming pressure of 50.0 kN, and the mechanical properties and shrinkage properties of mortar under different water-cement ratios were studied. The results show that the lower water-cement ratio plays a positive role in improving the performance of HBSC mortar. As the binder-wood fiber ratio increases from 0.8 to 3.0, the dry density of HBSC mortar of recycled wood fiber increases continuously, and the highest is 1 408 kg/m³, the compressive strength, flexural strength and shrinkage rate of mortar increase continuously. The 28 d compressive strength of mortar increases from 15.7 MPa to 32.4 MPa, and the 28 d flexural strength increases from 6.3 MPa to 12.2 MPa. The 28 d maximum shrinkage rate of mortar under different water-cement ratios is lower than 40.0×10^-5, the thermal conductivity is 0.317 6 W/(m·K), and the lightweight, high toughness, and insulation effect of recycled wood fiber high belite cement HBSC mortar are remarkable. In addition, the microscopic test results show that when the binder-wood fiber ratio is 3.0, the hydration of cement mortar is the most adequate and the internal pore structure is the most dense. This study can provide reference for the application of recycled wood fibers in lightweight, high-strength, and high-toughness insulation wall materials.
