Durable ecological concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses durable ecological concrete and a preparation method thereof. The durable ecological concrete is prepared from the following components in parts by weight: 200 to 300 parts of cement, 20 to 40 parts of silica fume, 40 to 60 parts of slag, 50 to 70 parts of fly ash, 400 to 600 parts of coarse aggregate, 20 to 30 parts of fly ash hollow microspheres, 10 to 30 parts of reinforced fibers and 100 to 150 parts of water, a preparation method of the durable ecological concrete comprises the following steps: adding the cement, the silica fume, the slag and the fly ash into a stirrer, carrying out dry mixing, adding 50% of water, continuously stirring to form uniform slurry, adding the coarse aggregate, the polyethylene glycol and 50% of water into the slurry, continuously stirring, adding the fly ash hollow microspheres and the reinforced fibers into the slurry, and uniformly stirring to obtain the durable ecological concrete. The durable ecological concrete disclosed by the invention solves the problems that the ecological concrete is relatively low in compressive property and tensile property and is easy to crack and damage in a use process.
本申请涉及混凝土领域，具体公开了一种耐久生态混凝土及其制备方法。耐久生态混凝土，按重量份计，包括水泥200‑300份、硅灰20‑40份、矿渣40‑60份、粉煤灰50‑70份、粗骨料400‑600份、粉煤灰空心微珠20‑30份、增强纤维10‑30份和水100‑150份；其制备方法为：将水泥、硅灰、矿渣和粉煤灰一同加入搅拌机中，进行干拌混合，加入50%的水，同时继续搅拌形成均匀的浆体，加入粗骨料、聚乙二醇和50%的水加入浆体，持续搅拌，将粉煤灰空心微珠和增强纤维加入浆体中搅拌均匀得到耐久生态混凝土。本申请的耐久生态混凝土解决了生态混凝土抗压性能和抗拉性能较低，在使用过程中容易出现开裂损坏的问题。
