Green high-performance recycled concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses green high-performance recycled concrete and a preparation method thereof. The green high-performance recycled concrete is prepared from the following raw materials in parts by weight: 100 to 120 parts of cement, 80 to 100 parts of natural fine aggregate, 150 to 250 parts of modified recycled coarse aggregate, 20 to 30 parts of modified recycled fine aggregate, 20 to 30 parts of nano silica fume powder and 40 to 60 parts of water, and the modified recycled coarse aggregate and the modified recycled fine aggregate are both prepared by the following steps: waste concrete is subjected to crushing, particle shaping, primary screening, soaking, drying, mineralized bacteria culture solution modification and secondary screening, and then recycled fine aggregate and recycled coarse aggregate are obtained. The green high-performance recycled concrete provided by the invention is excellent in anti-permeability performance.
本申请涉及建筑材料领域，具体公开了一种绿色高性能再生混凝土及其制备方法。一种绿色高性能再生混凝土，包括如下重量份的原料：水泥100‑120份、天然细骨料80‑100份、改性再生粗骨料150‑250份、改性再生细骨料20‑30份、纳米硅灰粉20‑30份、水40‑60份；所述改性再生粗骨料和改性再生细骨料均由如下步骤制得：废弃混凝土经破碎、颗粒整形、一次筛分、浸泡、干燥、矿化菌培养液改性、二次筛分后得到再生细骨料和再生粗骨料。本申请的绿色高性能再生混凝土抗渗性能优良。
