Abstract

The invention discloses a geopolymer fiber reinforced concrete. The geopolymer fiber reinforced concrete comprises the following components: geopolymer, recycled concrete aggregate and carbon fiber, wherein the geopolymer is a cementing material prepared from fly ash, slag, spontaneously combusting gangue and alkaline activator. According to the invention, industrial waste resources are made full use of; environmental destroy and pollution are reduced; production cost for the geopolymer fiber reinforced concrete is reduced; and the geopolymer fiber reinforced concrete has superior physical and chemical performances.

Description

technical field [0001] The invention relates to concrete, in particular to geopolymer fiber reinforced concrete, which belongs to the field of building materials. Background technique [0002] Concrete raw materials are widely used in industrial, civil and military engineering construction due to the convenience of raw materials, low price, and good modelability. As a result, the demand for concrete at home and abroad continues to increase, which also leads to concrete raw materials—— The demand for sand and cement is increasing day by day. [0003] As we all know, the large-scale mining of natural sand and gravel has caused damage to the ecological environment, and the dust and smoke emissions in the cement production process will also pollute the environment. As countries impose stricter restrictions on pollutant emissions, the environmental cost of cement production will become higher and higher. The continuously rising environmental cost forces large industrial enterpri...
