The invention discloses an efficient green building material, which is prepared from the following raw materials in parts by weight: 150 to 250 parts of Portland cement, 150 to 200 parts of water, 700 to 780 parts of medium sand, 800 to 900 parts of gravel, 200 to 250 parts of concrete waste, 50 to 100 parts of fly ash, 150 to 200 parts of mineral powder, 4 to 5 parts of water reducing agents, 2 to 3 parts of retarders and 1 to 5 parts of coated layered double hydroxides. The added coated layered double hydroxide can effectively relieve corrosion and has certain self-repairing performance, so that the obtained concrete material has good corrosion resistance and also has relatively good water permeability and freezing resistance.
本发明公开了一种高效绿色建筑材料，包括如下重量份数的原料：硅酸盐水泥150‑250份、水150‑200份、中砂700‑780份、碎石800‑900份、混凝土废料200‑250份、粉煤灰50‑100份、矿粉150‑200份、减水剂4‑5份、缓凝剂2‑3份、被包覆层状双氢氧化物1‑5份。所添加的被包覆层状双氢氧化物能够有效缓解腐蚀，并且具备一定的自修复性能，使得所得到的混凝土材料具有良好的耐腐蚀性，同时还具有较佳的透水性及抗冻性。
