Effect of Calcination Temperature of Dolomite on Properties of Self-insulation Wall Materials

The environmental pollution problem of Sinochem Chongqing Fuling Chemical Co., Ltd. is serious. District Party committee and government relocated the chemical plant as a whole started ecological restoration project. However, investigation found that soil covering greening failed to fundamentally eliminate harm caused by phosphorus slag environment. Therefore, resource utilization imperative. application dolomite rich in construction industry not only improves environment, but also reduces production cost self-insulation wall materials. In this experiment, was calcined at 600 ℃, 700 ℃ 800 respectively obtain light dolomite, which mixed into modified fly ash cement composite mortar prepare material. mechanical properties, water absorption, bulk density thermal insulation specimens were tested after curing for 7 28 days respectively. conclusions are follows: when calcination temperature specimen has best lowest largest insulation.
