Thermal insulation concrete and production method thereof

Abstract

The invention discloses a thermal insulation concrete and a production method thereof. The thermal insulation concrete comprises the following components in parts by weight: 100-120 parts of coal ash, 200-250 parts of cement, 50-75 parts of foamed plastic, 25-30 parts of foam glass, 40-55 parts of inflated mineral powder, 0-20 parts of silicate, 15-20 parts of sulfate, 80-100 parts of fine sand, 10-20 parts of silicon powder, 5-10 parts of talcum powder, 10-15 parts of a water reducing agent, 22-25 parts of a foaming agent and the balance of water, wherein the water-binder ratio is maintained at 0.5-0.6, the inflated mineral powder comprises inflated slag or float stone, the water reducing agent is poly-hydroxy acid, and the foaming agent is alkyl sulfate. By utilizing the manner, the thermal insulation concrete is light in mass, low in cost, small in heat transfer coefficient and good in thermal insulation property and sound insulation effect; the production method of the thermal insulation concrete is simple, and the operation process is easy to control.

Description

technical field [0001] The invention relates to the field of concrete for construction, in particular to a kind of thermal insulation concrete. Background technique [0002] In the situation of relatively tight resources, the energy consumption of residential buildings accounts for one-third of the national energy consumption. The existing buildings of nearly 40 billion square meters in my country are basically high-energy-consuming buildings, and the heating energy consumption per unit area is equivalent to The climatic conditions are 2-3 times that of developed countries. According to experts’ calculations, if the country is determined to pay close attention to building energy conservation from now on, fully enforce the design and application of building energy conservation for new buildings, and implement step by step for existing buildings. Energy-saving transformation, by 2020, my country's building energy consumption can reduce 335 million tons of standard coal, but if w...

[0002] In the situation of relatively tight resources, the energy consumption of residential buildings accounts for one-third of the national energy consumption. The existing buildings of nearly 40 billion square meters in my country are basically high-energy-consuming buildings, and the heating energy consumption per unit area is equivalent to The climatic conditions are 2-3 times that of developed countries. According to experts’ calculations, if the country is determined to pay close attention to building energy conservation from now on, fully enforce the design and application of building energy conservation for new buildings, and implement step by step for existing buildings. Energy-saving transformation, by 2020, my country's building energy consumption can reduce 335 million tons of standard coal, but if we continue to let it go, miss the current great opportunity, and do not take resolute and effective measures, the country's energy burden will be greatly increased in the long run. The sustainable development of my country's economy and society has been severely restricted, posing a major threat to energy security and the atmospheric environment
