High-strength freeze-thaw-resistant concrete prefabricated part and preparation method thereof
The invention relates to the technical field of concrete prefabricated parts, and particularly discloses a high-strength freeze-thaw-resistant concrete prefabricated part and a preparation method thereof. The high-strength and freeze-thaw-resistant concrete prefabricated part comprises the following components in parts by weight: 13-17 parts of modified fibers; 4-6 parts of an ethylene propylene diene monomer emulsion; 0.1 to 0.15 part of a vulcanizing agent; 0.1 to 0.2 part of an accelerant; 0.03 to 0.1 part of a coupling agent; 0-5 parts of fly ash; 40 to 50 parts of cement; 50 to 60 parts of sand; 10 to 15 parts of stone; 13 to 17 parts of water; 0.4 to 0.8 part of a water reducing agent; wherein a preparation method of the modified fiber comprises the following steps: adding ethylene glycol and nano powder into a water-based embedding wall material, and stirring and mixing to obtain a mixture A; adding hydrophilic fibers into the mixture A, dipping, filtering to remove filtrate, drying and curing to obtain a mixture B; adding a cross-linking agent into the mixture B, stirring and mixing, and filtering to remove filtrate to obtain the modified fiber. The product provided by the invention has the advantages of high strength, good freeze-thaw resistance and good waterproof performance.
本申请涉及混凝土预制件的技术领域，具体公开了一种高强度、抗冻融混凝土预制件及其制备方法。一种高强度、抗冻融混凝土预制件包括如下重量分数的组分：改性纤维13‑17份；三元乙丙橡胶乳液4‑6份；硫化剂0.1‑0.15份；促进剂0.1‑0.2份；偶联剂0.03‑0.1份；粉煤灰0‑5份；水泥40‑50份；砂50‑60份；石子10‑15份；水13‑17份；减水剂0.4‑0.8份；其中，所述改性纤维的制备方法为：向水性包埋壁材中加入乙二醇、纳米粉料，搅拌混合，得到混合物A；向混合物A中加入亲水纤维，浸渍、过滤去除滤液，干燥、固化，得到混合物B；向混合物B中加入交联剂，搅拌混合，过滤去除滤液，即得改性纤维。本申请的产品，其具有高强度、抗冻融性能好、防水性能好的优点。
