High-toughness synthetic fiber concrete and preparation method thereof
The invention discloses high-toughness synthetic fiber concrete and a preparation method thereof, and belongs to the field of building materials, the high-toughness synthetic fiber concrete comprises the following components by weight: 200-350 parts of cement; 833 to 900 parts of coarse aggregate; 650 to 735 parts of fine aggregate; 70 to 85 parts of fly ash; 4-7 parts of synthetic fiber; 12-18 parts of an expanding agent; 3.5 to 5.8 parts of a water reducing agent; 140 to 160 parts of water; the preparation method comprises the following steps: S1, mixing the cement, the coarse aggregate and the fine aggregate, putting into a concrete stirrer, and uniformly stirring to obtain a concrete powder premixture; s2, uniformly mixing fly ash and synthetic fibers, then adding the mixture into the concrete powder premixture, and stirring while vibrating to prepare concrete powder; and S3, adding a certain amount of water into the concrete powder, uniformly stirring, adding an expanding agent and a water reducing agent, and uniformly stirring to obtain the concrete slurry. The production process is simple, and the prepared concrete has relatively high tensile strength and breaking strength, good toughness and difficulty in cracking.
本发明公开了一种高韧性合成纤维混凝土及其制备方法，属于建筑材料领域，该高韧性合成纤维混凝土按重量份包括以下组分：按重量分包括以下组分：水泥200‑350份；粗骨料833‑900；细骨料650‑735份；粉煤灰70‑85份份；合成纤维4‑7份；膨胀剂12‑18份；减水剂3.5‑5.8份；水140‑160份；其制备方法如下：S1：取水泥、粗骨料、细骨料混合，投入混凝土搅拌器，搅拌均匀，获得混凝土粉料预混合物；S2：将粉煤灰和合成纤维混合均匀，然后加入到混凝土粉料预混合物中，边振动边搅拌，制得混凝土粉料；S3：取一定量的水加入到混凝土粉料中，搅拌均匀，再加入膨胀剂合减水剂，搅拌均匀，获得混凝土浆料。本发明生产过程简单，制备的混凝土有着较高的抗拉强度和抗折强度，韧性好，不容易开裂。
