Flame-retardant concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses flame-retardant concrete and a preparation method thereof.The flame-retardant concrete is prepared from, by weight, cement, fly ash, silica fume, gravel, sand, water, a water reducing agent, filling fibers and flame-retardant filler; the flame-retardant filler is composed of aluminum hydroxide, antimony trioxide and coated ammonium polyphosphate; the preparation method comprises the following steps: uniformly mixing cement, aluminum hydroxide and antimony trioxide, and spraying water which is 1/12-1/10 of the total amount of water to prepare a cement mixture; uniformly mixing the fly ash and the silica fume to prepare powder; uniformly mixing the gravels and the sand to prepare aggregate; uniformly mixing the filling fibers and the coated ammonium polyphosphate to obtain a filling material; uniformly mixing the cement mixture with the powder material, uniformly mixing the aggregate with the filler, adding the rest of water and the water reducing agent, and uniformly mixing to obtain a mixed material; and pouring and curing the mixed material to obtain a finished product. The influence of fire high temperature on the concrete strength is reduced, and the safe evacuation time of high-rise residents is prolonged.
本申请涉及混凝土领域，具体公开了一种阻燃混凝土及其制备方法，一种阻燃混凝土，包含以下重量份的原料制成：水泥、粉煤灰、硅灰、碎石、砂、水、减水剂、填充纤维、阻燃填料；阻燃填料由氢氧化铝、三氧化二锑和包膜聚磷酸铵组成；其制备方法为：水泥与氢氧化铝、三氧化二锑混合均匀，喷洒水总量1/12‑1/10的水，制得水泥混料；粉煤灰、硅灰混合均匀，制得粉料；碎石和砂混合均匀，制得骨料；填充纤维、包膜聚磷酸铵混合均匀，制得填充料；水泥混料和粉料混合均匀，骨料和填充料混合均匀，再添加剩余的水和减水剂，混合均匀，制得拌和料；拌和料经浇筑、养护，制得成品；降低火灾高温对混凝土强度的影响，延长高层居民的安全撤离时间。
