The invention discloses an improved aerated concrete block, which is prepared from the following raw materials in parts by weight: 100 to 150 parts of siliceous material, 22 to 45 parts of cement, 20 to 40 parts of quick lime, 5 to 15 parts of desulfurized gypsum, 0.2 to 0.25 part of aluminum powder and 0.2 to 0.5 part of modified carbon nanotube. The modified carbon nanotube is prepared by the following steps: putting carbon nanotube powder into a closed container, introducing nitrogen, adjusting the flow and air pressure of the nitrogen, and carrying out microwave irradiation at the same time, so that gas in a cavity absorbs microwave energy and is excited to generate plasma; adding ultrasonic irradiation to make the ionized nitrogen atoms deeply doped into the surface and the internal structure of the carbon nanotube; and adding the obtained carbon nanotube into an acetic acid solution of chitosan, reacting for 6-8 hours at the temperature of 30-35 DEG C, and performing suction filtration, washing and drying to obtain the modified carbon nanotube material.
本发明公开了一种改良的加气混凝土砌块，原料按重量份数计如下；硅质材料100‑150份、水泥22‑45份、生石灰20‑40份、脱硫石膏5‑15份、铝粉0.2‑0.25份和改性碳纳米管0.2‑0.5份；所述改性碳纳米管按以下方式制备而来：将碳纳米管粉末置于密闭容器并通入氮气，调节氮气流量、气压，同时进行微波照射，使得腔体内部气体吸收微波能量并激发产生等离子体；增加超声波照射，等离子化后的氮原子深层次掺到碳纳米管表面和内部结构中；所得碳纳米管加入壳聚糖的醋酸溶液，30‑35℃反应6‑8h，抽滤，洗涤，干燥，获得改性碳纳米管材料。
