Early-strength anti-freezing fine aggregate concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses early-strength anti-freezing fine aggregate concrete and a preparation method thereof. The early-strength anti-freezing fine aggregate concrete is prepared from the following raw materials in parts by weight: 280 to 315 parts of cement, 1300 to 1550 parts of fine aggregate, 560 to 670 parts of sand, 150 to 160 parts of water, 5.8 to 7.4 parts of an additive, 4 to 12 parts of coated silica gel particles, 2 to 10 parts of modified basalt and 4 to 15 parts of grafted fibers, the preparation method comprises the following steps: S1, weighing the cement and the coated silica gel particles, uniformly mixing, adding the grafted fibers, and uniformly mixing to obtain a primary mixture; s2, fine stone, sand and modified basalt stone are weighed, mixed and stirred to be uniform, and a sand-stone material is prepared; s3, uniformly mixing the primary mixture with the sand-gravel material, adding water and an additive, and uniformly mixing and stirring to obtain a finished product, and the fine aggregate concrete has good anti-freezing performance.
本申请涉及混凝土技术领域，具体公开了一种早强防冻细石混凝土及其制备方法；一种早强防冻细石混凝土，包含以下重量份的原料制成：水泥280‑315份、细石1300‑1550份、砂560‑670份、水150‑160份、外加剂5.8‑7.4份、包膜硅胶颗粒4‑12份、改性玄武岩石2‑10份，接枝纤维4‑15份；其制备方法为：S1、称取水泥、包膜硅胶颗粒混合均匀后，添加接枝纤维混合均匀，制得初混料；S2、称取细石、砂、改性玄武岩石混合搅拌均匀，制得砂石料；S3、初混料与砂石料混合均匀后，添加水、外加剂混合搅拌均匀，制得成品；使细石混凝土具有较好的防冻性能。
