Treatment method of pine needle fibers and preparation method of pine needle fiber concrete
The invention relates to a pine needle fiber treatment method and a pine needle fiber concrete preparation method. Pine needles are newly collected from trees, the collected pine needles are rolled into a flat shape by using a heavy object, the pine needles are put into a sodium hydroxide (NaOH) solution and soaked for 5-8 hours, and then the soaked pine needles are washed by clear water and air-dried; water, cement, sand and stone are prepared according to the mass ratio of 0.41: 1: 1.862: 2.304; the cement, sand, stone and water are sequentially added into a stirrer for pre-stirring; and finally, the air-dried pine needles are added, and continuously and uniformly stirred. The ductility and the toughness of the concrete are improved, the production cost of the fiber concrete is reduced,and meanwhile, the requirements of green, efficient and environment-friendly materials are met.
一种松叶纤维的处理及松叶纤维混凝土的制备方法，松叶为树上采集的新叶，采集后将其用重物碾压成扁平状，放入氢氧化钠NaOH溶液中浸泡5‑8小时，然后将浸泡后的松叶用清水冲洗，风干；按照质量比为0.41：1：1.862：2.304配置水、水泥、砂和石；将水泥、砂、石、水依次放入搅拌机，进行预搅拌；最后掺入风干后的松叶，继续搅拌均匀即可；既提高了混凝土的延性、韧性，又降低了纤维混凝土的生产成本，同时符合绿色高效环境友好型材料的要求。
