Modified wheat straw fiber reinforced foam concrete backfill material and preparation and use methods thereof
The invention discloses a modified wheat straw fiber reinforced foam concrete backfill material and a preparation and use method thereof, and belongs to the field of civil engineering foundation fill construction. The backfill material is composed of concrete dry powder, a composite foaming agent and modified wheat straw fibers, the modified wheat straw fibers corrode wheat straw broken sections through alkali liquor, then the alkali-corroded wheat straw broken sections are immersed in fiber surface coating film glue liquid, or a layer of fiber surface coating film glue liquid is directly sprayed on the surfaces of the alkali-corroded wheat straw broken sections, and the modified wheat straw fibers are formed. Therefore, a layer of fiber surface coating film is attached to the surface of the crushed wheat straw section. During use, the concrete dry powder, the composite foaming agent and the modified wheat straw fiber are mixed into slurry according to a proportion, and the slurry is filled into a fertilizer groove. According to the invention, the modified wheat straw fiber is added into the foamed concrete, so that the defects of poor shear resistance and weak impact resistance of the traditional foam concrete filling material are overcome, and the additional industry value of wheat straw is increased.
本发明公开了一种改性麦秸纤维增强泡沫混凝土回填材料及制备和使用方法，属于土木工程基础填方施工领域。该回填材料由混凝土干粉、复合发泡剂和改性麦秸纤维三部分组成，所述的改性麦秸纤维利用碱液腐蚀麦秸碎段，然后将碱蚀后的麦秸碎段浸入纤维表面包覆膜胶液中，或者直接在碱蚀后的麦秸碎段表面喷洒一层纤维表面包覆膜胶液，从而使得在麦秸碎段表面附着一层纤维表面包覆膜。使用时，将混凝土干粉、复合发泡剂和改性麦秸纤维按比例混合成浆液填充到肥槽中。本发明在发泡混凝土中加入改性后的麦秸纤维，不但克服传统泡沫混凝土填充材料抗剪切能力差和抗冲击能力弱的缺陷，同时提高了麦秸的附加产业值。
