Recycled micro-powder concrete and preparation method thereof
The invention relates to the technical field of recycled concrete, and discloses recycled micro-powder concrete and a preparation method thereof. The recycled micro-powder concrete is prepared from the following raw materials in parts by weight: 210 to 310 parts of natural aggregate, 550 to 810 parts of recycled aggregate, 120 to 200 parts of modified silica fume, 300 to 440 parts of cement, 80 to 150 parts of an additive, 10 to 30 parts of a water reducing agent, 580 to 700 parts of sand and 110 to 162 parts of water, wherein the modified silica fume is prepared from a titanate coupling agent, sorbitol and silica fume in a weight ratio of (1-5): (2.2-6): (89-97.8). According to the present invention, the specific raw materials and the specific ratio are adopted, the prepared recycled concrete has excellent comprehensive performance, the modified silica fume is introduced, such that the interface region between the recycled concrete and the natural concrete is effectively reinforced, and the crack resistance of the recycled concrete is significantly improved.
本申请涉及再生混凝土技术领域，本申请公开了一种再生微粉混凝土及其制备方法。一种再生微粉混凝土，包括以下重量份数原料：天然骨料210‑310份，再生骨料550‑810份，改性硅灰120‑200份，水泥300‑440份，添加剂80‑150份，减水剂10‑30份，砂580‑700份，水110‑162份；其中，所述改性硅灰由包括重量比为1‑5:2.2‑6:89‑97.8的钛酸酯偶联剂、山梨糖醇和硅灰制得。本申请采用特定的原料以及配比，制备得到的再生混凝土综合性能优异，通过引入改性硅灰，本申请有效地强化了再生混凝土与天然混凝土之间的界面区域，显著提高了再生混凝土的抗裂性能。
