The invention relates to the technical field of concrete, and particularly discloses light recycled concrete and a preparation method thereof. The light recycled concrete is prepared from the following raw materials in parts by weight: 200 to 330 parts of cement, 50 to 90 parts of fly ash, 600 to 750 parts of pottery sand, 160 to 210 parts of silica fume, 150 to 180 parts of water, 20 to 90 parts of rice hull ash, 20 to 50 parts of hybrid fiber, 330 to 400 parts of fine aggregate, 580 to 630 parts of recycled coarse aggregate, 50 to 80 parts of modified waste rubber powder and 5 to 10 parts of polycarboxylic acid water reducing agent. The preparation method comprises the following steps: mixing and stirring the cement, the fly ash, the ceramsite, the silica fume, the rice hull ash and the hybrid fiber, adding the water and the polycarboxylic acid water reducer, stirring, adding the other raw materials, and stirring to obtain the light recycled concrete. The light recycled concrete provided by the invention has the advantage of better strength through the synergistic effect of the raw materials.
本申请涉及混凝土技术领域，具体公开了一种轻质再生混凝土及其制备方法。一种轻质再生混凝土由包括以下重量份的原料制成：水泥200‑330份、粉煤灰50‑90份、陶砂600‑750份、硅灰160‑210份、水150‑180份、稻壳灰20‑90份、混杂纤维20‑50份、细骨料330‑400份、再生粗骨料580‑630份、改性废橡胶粉50‑80份、聚羧酸减水剂5‑10份；其制备方法为：先将水泥、粉煤灰、陶粒、硅灰、稻壳灰、混杂纤维混合并搅拌，加入水、聚羧酸减水剂搅拌，再加入其余原料搅拌，得到轻质再生混凝土。本申请的一种轻质再生混凝土，通过原料之间的协同作用，其具有更好的强度的优点。
