Betel nut shell fiber reinforced cement mortar and preparation method thereof
The invention discloses betel nut shell fiber reinforced cement mortar and a preparation method thereof. The method comprises the following steps: uniformly stirring cement, sand and water according to a mass ratio of 1: 2: 0.35 to form cement mortar, doping the treated betel nut shell fibers into the mortar according to 0.25-1% of the volume of the mortar, and mechanically stirring until the fibers are uniformly distributed. Then injecting into a mold for curing and molding, thoroughly wrapping all mortar samples in wet cloth and polyethylene, curing for 24 hours under the indoor conditions that the relative humidity is 90 +/-5% and the temperature is 20 +/-3 DEG C, and demolding. And curing for 7, 14 and 28 days under a pond water maintenance condition (20 +/-3 DEG C). The betel nut shell fiber reinforced cement mortar is prepared. The betel nut shell fiber has the advantages of high tensile strength, good toughness and the like, after the glass betel nut shells are added into the mortar, the mechanical strength, the shrinkage rate and the porosity of the mortar can be remarkably improved, and meanwhile, the adverse effect of the waste betel nut shells on the environment can be reduced.
本发明公开了一种槟榔壳纤维增强水泥砂浆及其制备方法。先将水泥、砂、水以1：2：0.35的质量比进行均匀搅拌形成水泥砂浆，之后将处理好的槟榔壳纤维以砂浆体积的0.25％‑1％掺入砂浆并进行机器搅拌至均匀分布。之后注入模具固化成型，将所有砂浆样本彻底包裹在湿布和聚乙烯中，在相对湿度90±5％，温度20±3℃室内条件下养护24小时后脱模。在池塘水养护条件(20±3℃)下固化7、14和28天。制得槟榔壳纤维增强水泥砂浆。槟榔壳纤维具有抗拉强度高、韧性好等优点，砂浆中加入玻璃槟榔壳后可以显著提高砂浆的力学强度、收缩率和孔隙率，同时还可以减少废弃槟榔壳给环境带来的不利影响。
