Method for preparing recycled concrete based on activated water and recycled concrete
The invention relates to a method for preparing recycled concrete based on activated water and the recycled concrete, and relates to the technical field of building materials. The recycled concrete is prepared from the following raw materials in parts by weight: 1000 to 1500 parts of recycled coarse aggregate, 550 to 660 parts of fine aggregate, 220 to 320 parts of ordinary Portland cement, 15 to 40 parts of diatomite modified layered double hydroxide microcapsules, 25 to 40 parts of mineral admixture, 1 to 6 parts of water reducing agent and 150 to 220 parts of activated water. The diatomite modified layered double hydroxide microcapsule comprises a capsule core, a capsule wall and diatomite, wherein the diatomite is loaded on the surface of the capsule wall, the capsule core comprises layered double hydroxide, and the capsule wall is made of a temperature sensitive material. The invention has the effect of improving the durability of the concrete.
本申请涉及基于活化水制备再生混凝土的方法及再生混凝土，涉及建筑材料技术领域。再生混凝土包括如下重量份的原料制成：再生粗骨料1000‑1500份、细骨料550‑660份、普通硅酸盐水泥220‑320份、硅藻土改性层状双氢氧化物微胶囊15‑40份、矿物掺合料25‑40份、减水剂1‑6份和活化水150‑220份，所述硅藻土改性层状双氢氧化物微胶囊包括囊芯、囊壁和硅藻土，所述硅藻土负载于囊壁表面，所述囊芯包括层状双氢氧化物，所述囊壁为温度敏感材料。本申请具有提升混凝土耐久性的效果。
