The invention relates to the technical field of recycled concrete, and particularly discloses thermal insulation type recycled concrete which comprises the following substances in parts by weight: 30-40 parts of cement, 8-15 parts of fly ash, 80-100 parts of recycled coarse aggregate, 15-20 parts of recycled fine aggregate, 20-30 parts of sand, 20-30 parts of water, 3-5 parts of a water reducing agent and 5-10 parts of aerogel particles. The heat conductivity coefficient of the aerogel particles is 0.025 W/(m.k) to 0.030 W/(m.k), and the particle size of the aerogel particles is 0.8 mm to 1.2 mm. The aerogel particles are added into the recycled concrete to serve as a modified material, the heat preservation effect of the concrete is improved, meanwhile, due to the fact that aerogel has the high specific surface area, the aerogel is added into the concrete, the bonding strength of materials in the concrete can be effectively filled and improved, and therefore the structure of the recycled concrete material is compacted, and further, the mechanical property of the recycled concrete material is effectively improved.
本申请涉及再生混凝土技术领域，具体公开了一种保温型再生混凝土，保温型再生混凝土包括下列重量份物质：水泥30～40份、粉煤灰8～15份、再生粗骨料80～100份、再生细骨料15～20份、砂20～30份、水20～30份、减水剂3～5份、气凝胶颗粒5～10份；所述气凝胶颗粒的导热系数为0.025～0.030W/（m·k），所述气凝胶颗粒粒径为0.8～1.2mm。本申请在再生混凝土中添加气凝胶颗粒为改性材料，改善混凝土的保温效果，同时由于气凝胶具有较高的高比表面积，将其添加至混凝土内部，能有效填充并改善混凝土内部材料中的结合强度，从而密实再生混凝土材料的结构，进而有效提高了再生混凝土材料的力学性能。
