Preparation process of organic fiber additive for concrete
The invention discloses a preparation process of an organic fiber additive for concrete, and relates to the technical field of PVC pipe preparation, and the preparation process specifically comprises the following steps: adding a chitosan-nano silver ion composite antibacterial agent into a polycarboxylic acid water reducer, and stirring to obtain a uniform mixture, namely the antibacterial agent for high-strength and high-performance concrete. According to the concrete additive disclosed by the invention, the antibacterial agent is added into the concrete additive, and the prepared concrete does not easily breed infectious microbes even if being used in a relatively humid environment in a use process, so that the whole prepared concrete has relatively good antibacterial property and corrosion resistance, the durability of the concrete is improved, and the service life of the concrete is prolonged. The organic fiber and the basalt fiber are doped, so that the prepared concrete and aggregate form a relatively good occlusion force, the defect of a multi-pore structure of ceramsite concrete is overcome, and the fiber is used as a secondary reinforcement material of the concrete and can also improve the crack resistance, the impermeability and the impact resistance of the concrete.
本发明公开了一种用于混凝土的有机纤维添加剂的制备工艺，涉及PVC管材制备技术领域，具体包括以下步骤：将壳聚糖‑纳米银离子复合抗菌剂投入聚羧酸减水剂中，搅拌得到均一混合物即为用于高强高性能混凝土抗菌剂。之后将抗菌剂加入到混凝土添加剂的内部，制备得到的混凝土在使用过程中，即使在较为潮湿的环境中使用时，也不会轻易滋生杂菌，从而使得整个制得的混凝土具有较好的抗菌性和抗腐蚀能力，增加了混凝土的耐用性和使用寿命。有机纤维和玄武岩纤维的掺加使得制得的混凝土与骨料形成较好的咬合力，弥补了陶粒混凝土过多孔结构的缺陷，纤维作为混凝土的次要加筋材料，还可提高混凝土抗裂、抗渗和抗冲击能力。
