Lightweight concrete with low thermal conductivity
The invention discloses lightweight concrete with low thermal conductivity, which is prepared from the following raw materials in percentage by weight: 95 to 99 percent of aggregate and 1 to 5 percent of composite additive. The aggregate is prepared from the following components in percentage by weight: 1 to 60 percent of cement, 1 to 30 percent of silica powder, 1 to 20 percent of mullite, 0.5 to 3 percent of zirconium oxide fiber, 5 to 20 percent of antioxidant material and the balance of water. The composite additive is prepared by mixing the following components in parts by weight: 0.1-1.2 parts of aerogel particles, 8-20 parts of an adhesive, 1-5 parts of an alkali reagent, 0.1-1 part of a foaming agent and 5-15 parts of a dispersing agent. According to the invention, by improving the pore structure of the concrete, the pore distribution is more uniform, and the product has a good pore structure, so that the product has higher strength and excellent thermal performance.
本发明公开了一种具有低热导率的轻质混凝土，所述原料的组成，按重量百分比计为：骨料95～99％、复合添加剂1～5％；所述骨料组成以重量百分比计为：水泥1～60％、硅微粉1～30％、莫来石1～20％、氧化锆纤维0.5～3％、抗氧化材料5～20％、水余量；所述复合添加剂以重量份计，由气凝胶颗粒0.1～1.2份、粘接剂8～20份、碱试剂1～5份、发泡剂0.1～1份、分散剂5～15份混合而成。本发明通过改善混凝土的孔结构，气孔分布更加均匀，具有良好的气孔结构，使制品具有较高的强度和优异的热工性能。
