Preparation method of high-strength fiber concrete wall
The embodiment of the invention discloses a preparation method of a high-strength fiber concrete wall. The method comprises the following steps: S1, mixing 30-45 parts by mass of cement, 25-35 parts by mass of fly ash, 3-7 parts by mass of fibers for concrete, 5-10 parts by mass of silica fume, 35-50 parts by mass of fine sand, 4-8 parts by mass of fine aggregate and 5-10 parts by mass of a waterrepellent, and uniformly stirring to obtain a dry-mixed material; S2, adding 16-25 parts of water and 6-12 parts of an early strength agent, and stirring for 1-3 min at the stirring speed of 600-1000rpm, to obtain mixed slurry; S3, adding 3-8 parts of a water reducing agent, and stirring for 80-150 s at the stirring speed of 800-1500 rpm, to obtain fiber concrete; and S4, pouring the fiber concrete into a built wall cast-in-place frame. According to the preparation method of the high-strength fiber concrete wall, the concrete wall has the advantages of high strength and high ductility, and shear brittle failure can be effectively resisted.
本申请实施例公开了一种高强度纤维混凝土墙体的制备方法，按质量份计，该方法包括以下步骤：S1、将30～45份的水泥、25～35份的粉煤灰、3～7份的混凝土用纤维、5～10份的硅灰、35～50份的细砂、4～8份的细骨料、5～10份的憎水剂混合后搅拌均匀，得到干拌料；S2、加入16～25份的水、6～12份的早强剂，按照搅拌速度600～1000rpm，搅拌1～3min，得到混合浆料；S3、加入3～8份的减水剂，按照搅拌速度800～1500rpm，搅拌80～150s，得到纤维混凝土；S4、向搭建好的墙体现浇框架中浇筑所述纤维混凝土。根据本申请的高强度纤维混凝土墙体的制备方法，使混凝土墙体具有高强度、高延性的优点，能够有效地抵抗剪切脆性破坏。
