Lightweight high-strength concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, and particularly discloses lightweight high-strength concrete and a preparation method thereof. The lightweight high-strength concrete comprises the following components: cement, silica fume, fly ash, hollow glass beads, ceramsite, titanium boride particles, polyamide fibers, a water reducing agent and water. The preparation method comprises the following steps: 1, uniformly mixing cement, silica fume, fly ash, hollow glass beads and water to obtain premixed concrete; and 2, adding ceramsite, titanium boride particles, fibers and a water reducing agent into the premixed concrete, and stirring for 45 minutes to obtain the uniformly stirred lightweight high-strength concrete. The lightweight high-strength concrete can be used in the construction fields of super high-rise buildings, bridges and the like, and has the advantages of small volume weight, high compressive strength and stable working performance.
本申请涉及混凝土制备的技术领域，具体公开了一种轻质高强混凝土及其制备方法。轻质高强混凝土包括如下的组分：水泥、硅灰、粉煤灰、空心玻璃微珠、陶粒、硼化钛颗粒、聚酰胺纤维、减水剂和水；其制备方法为：步骤一，将水泥、硅灰、粉煤灰、空心玻璃微珠和水混合均匀得到预拌混凝土；步骤二，将陶粒、硼化钛颗粒、纤维和减水剂加入预拌混凝土中，搅拌4‑5min得到搅拌均匀的轻质高强混凝土。本申请的轻质高强混凝土可用于超高层建筑、桥梁等施工领域，其具有容重小、抗压强度高、工作性能稳定的优点。
