Phase change heat storage foam concrete as well as preparation method and application thereof
The invention belongs to the technical field of concrete, and particularly relates to phase change heat storage foam concrete as well as a preparation method and application thereof. The phase change heat storage foam concrete provided by the invention is prepared from the following raw materials: 50-70% of cement, 2-20% of a supported phase change material, 15-35% of water, 0.1-0.5% of a water reducing agent, 0.5-1.5% of a foam stabilizer, 0.5-2% of a hydrogen peroxide aqueous solution and 0.1-0.4% of a hydrogen peroxide decomposition catalyst, the supported phase change material comprises acid modified fly ash and paraffin supported on the surface and in a pore structure of the acid modified fly ash; the mass percentage content of the hydrogen peroxide aqueous solution is 25-30%. The phase change heat storage foam concrete provided by the invention has the advantages of low heat conductivity coefficient, obviously improved heat absorption capacity and lower production cost, can be massively used in actual production, and reduces the construction cost.
本发明属于混凝土技术领域，具体涉及一种相变蓄热泡沫混凝土及其制备方法和应用。本发明提供的相变蓄热泡沫混凝土的制备原料包括：水泥50～70％，负载型相变材料2～20％，水15～35％，减水剂0.1～0.5％，稳泡剂0.5～1.5％，过氧化氢水溶液0.5～2％，过氧化氢分解催化剂0.1～0.4％；所述负载型相变材料包括酸改性粉煤灰和负载在所述酸改性粉煤灰表面和孔结构中的石蜡；所述过氧化氢水溶液的质量百分含量为25～30％。本发明提供的相变蓄热泡沫混凝土导热系数低，吸热能力显著提高，生产成本较低，可大量用于实际生产中，降低工程造价。
