Lightweight high-strength concrete material
The invention discloses lightweight high-strength concrete. The concrete comprises the following raw materials in parts by mass: iron ore slag, calcium d-arabinoate and glyceride d-arabinoate modifiedfly ash, nano ceramic fiber, nano aluminum oxide, basalt fiber, high-efficiency water reducing agent, Portland cement, sand, crushed stone, sodium carbonate, sodium hydroxide and water, wherein the ratio of the iron ore slag to the D-arabinose acid calcium and D-arabinose acid glyceride modified fly ash to the nano ceramic fiber to the nano aluminum oxide to the basalt fiber to the high-efficiency water reducing agent to the Portland cement to the sand to the crushed stone to the sodium carbonate to the sodium hydroxide to the water is 1:(0.05-0.15):(0.04-0.12):(0.01-0.03):(0.05-0.3):(0.005-0.02):(1.5-3.5):(2-4):(3.5-6.5):(0.04-0.08):(0.05-0.15):(0.5-1). According to the invention, the modified fly ash is added into the concrete through the calcium d-arabinoate and the glyceride d-arabinoate; and hydroxyl groups in the calcium d-arabinoate and the glyceride d-arabinoate form Si-O---H-O-CH2(CHOH)3COO-Al-O-Si bonds through intermolecular force, so that the tensile strength of the concrete is further enhanced.
本发明公开了一种轻质高强的混凝土，包括以下质量比原料配比为：铁矿渣：D‑阿拉伯糖酸钙和D‑阿拉伯糖酸甘油酯改性的粉煤灰：纳米陶瓷纤维：纳米氧化铝：玄武岩纤维：高效减水剂：硅酸盐水泥：砂：碎石：碳酸钠：氢氧化钠：水＝1：0.05～0.15：0.04～0.12：0.01～0.03：0.05～0.3：0.005～0.02：1.5～3.5：2～4：3.5～6.5：0.04～0.08：0.05～0.15：0.5～1。本发明通过在混凝土中通过D‑阿拉伯糖酸钙和D‑阿拉伯糖酸甘油酯添加改性的粉煤灰，D‑阿拉伯糖酸钙和D‑阿拉伯糖酸甘油酯中的羟基通过分子间作用力形成Si‑O‑‑‑H‑O‑CH(CHOH)COO‑Al‑O‑Si键，进一步增强混凝土的抗拉强度。
