Carbonized recycled coarse aggregate concrete and preparation method thereof
The invention discloses carbonized recycled coarse aggregate concrete and a preparation method thereof, and the carbonized recycled coarse aggregate concrete is prepared from the following components in parts by weight: 300 to 380 parts of cement, 800 to 920 parts of modified recycled coarse aggregate, 600 to 820 parts of fine aggregate, 80 to 160 parts of lightweight aggregate, 40 to 92 parts of reinforced fiber, 6.2 to 10.6 parts of water reducing agent and 100 to 132 parts of water; wherein the modified recycled coarse aggregate is obtained by carbonizing recycled coarse aggregate and then modifying the carbonized recycled coarse aggregate with a modification liquid, the modification liquid comprises modified epoxy resin, and the modified epoxy resin is obtained by grafting epoxy resin with silicon dioxide. According to the carbonized recycled coarse aggregate concrete prepared in the invention, natural coarse aggregate is completely replaced by the carbonized recycled coarse aggregate, carbon emission is reduced, exploitation of the natural coarse aggregate is reduced, and the carbonized recycled coarse aggregate concrete is an environment-friendly and high-performance building material.
本申请公开了一种碳化再生粗骨料混凝土及其制备方法，其中碳化再生粗骨料混凝土，按照重量份计，包括如下组分：300‑380份水泥，800‑920份改性再生粗骨料，600‑820份细骨料，80‑160份轻骨料，40‑92份强化纤维，6.2‑10.6份减水剂，100‑132份水；其中，改性再生粗骨料由再生粗骨料经过碳化，再通过改性液改性后得到，所述改性液包括改性环氧树脂，所述改性环氧树脂通过环氧树脂接枝二氧化硅得到。本申请制备得到的碳化再生粗骨料混凝土，用碳化再生粗骨料完全代替天然粗骨料，减少了碳排放的同时还减少了天然粗骨料的开采，是一种环保且高性能的建筑材料。
