Light inorganic material as well as preparation method and application thereof
The invention discloses a light inorganic material which is prepared from the following raw materials in parts by weight: 200-300 parts of cement, 36-54 parts of fly ash, 319-345 parts of modified ceramsite, 398-484 parts of modified pottery sand, 20-50 parts of inorganic prefabricated hollow aggregate, 10-15 parts of hollow glass beads, 0.10-0.20 part of an air entraining agent, 2.7-4.1 parts of a water reducing agent and 145-155 parts of water. According to the invention, the problem of poor anti-freezing and anti-seepage durability of the thermal insulation concrete due to high water absorption rate of the porous lightweight aggregate is solved, the heat conductivity coefficient of the thermal insulation concrete is reduced, and the mechanical property and durability are improved. The characteristics of high strength, moisture and heat preservation, aging resistance, excellent durability and the like are realized. In addition, the material has the characteristics of light weight, low heat conductivity coefficient, high strength, excellent durability, strong ice pulling resistance and the like, can be used as a hydraulic mass concrete surface permanent thermal insulation material, can also be used as a template for concrete pouring, is convenient to construct, and improves the operation efficiency.
本发明公开了一种轻质无机材料，由以下重量份数的原材料制成：水泥200～300，粉煤灰36～54，改性陶粒319～345，改性陶砂398～484，无机预制空心骨料20～50，空心玻璃微珠10～15，引气剂0.10～0.20，减水剂2.7～4.1，水145～155。本发明解决了多孔轻骨料因吸水率高，而导致保温混凝土抗冻与抗渗耐久性差的问题，降低了保温混凝土导热系数，并提高了力学性能与耐久性能。具有高强、保湿保温、耐老化、耐久性优等特点。另外，本发明还具有质轻、导热系数低、高强、耐久性优、抗冰拔能力强等特点，作为水工大体积混凝土表面永久保温材料，同时可兼作混凝土浇筑用模板，施工方便，提高作业效率。
