[0033] The cements in Table 1 and Table 2 refer to various general cements or special cements.

[0034] The water reducer in Table 1 is a component commonly used in concrete, such as naphthalene-based water reducer.

[0035] The composite admixtures in Table 1 are commercially available fine materials for concrete.

[0036] In Table 1 and Table 2, cement, fly ash, slag powder, composite admixture, silica fume, and high-fine dust collection ash are the cementitious materials.

[0037] The high-fine dust collection ash in the table can be directly added to the concrete raw materials, or the high-fine dust collection ash can be mixed into the cement first, or the high-fine dust collection ash can be mixed with slag powder and fly ash first. In, mixed with other raw materials, the effect is basically the...

Abstract

The present invention relates to an application of high-fine recovered dust ash of cement plant. Said high-fine recovered dust ash can be used as concrete blending material or component of concrete blending material. Said high-fine recovered dust ash is added in the concrete, it can raise compaction degree of cementing material in concrete and can raise early strength of concrete, and can reduce production cost of concrete.

Description

technical field [0001] The invention belongs to a concrete production method, and particularly relates to a new application of high-fine dust collection in a cement plant, and the high-fine dust collection refers to the high-fine dust collection at the end of a pre-decomposition kiln or / and the high-fine collection dust of a raw meal mill. Background technique [0002] The main production process of cement enterprises is: raw material grinding → clinker calcination → cement grinding → finished cement. A large amount of dust will be generated in the production process of each process, so cement enterprises use a large number of dust collection equipment, and electrostatic precipitator and bag filter are the main ones. The traditional process method to deal with the high and fine dust generated by the dust collector is generally, the dust generated by the raw material system and the preheating system of the kiln tail of the precalcining kiln is returned to the raw material sto...
