Technology of producing high strength cement by utilizing industrial waste residue

Abstract

The invention discloses a process for producing high-strength cement by using industrial waste residues, which comprises the following process steps: 1) the production of a cement clinker: carrying out proportioning and controlling fed materials to carry out raw material grinding and raw material homogenizing according to a proportioning scheme that the high silicon rate N is 3.10, the high alumina rate P is 1.80 and the high limestone saturation rate KH is 0.80, feeding raw materials into a rotary calcining kiln to be calcined, and then producing the cement clinker; and 2) the production of a cement product: selecting six raw materials such as fly ash, stone powder, the cement clinker, desulfurization gypsum, dicyandiamide residues, and metal magnesium reduced powder by using a microcomputer to proportion in percentage by weight, controlling fed materials to carry out cement grinding and cement homogenizing, and then producing the cement product. The process disclosed by the invention has the advantages that the process both complies with the environmental-friendly concept of protecting the environment and reducing the pollution, and has the positive social effects of changing waste material into things of value and reducing the disposal and production costs of industrial waste residues, and produced cement is stable in quality and high in strength.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a process for producing high-strength cement by using industrial waste residue. Background technique [0002] The use of industrial waste residues to produce cement not only conforms to the environmental protection concept of protecting the environment and reducing pollution, but also has positive social effects of turning waste into treasure, reducing industrial waste disposal and production costs. At present, some cement companies have successfully used industrial waste residues to produce cement. However, it is not difficult to see that the existing disclosed technologies utilizing industrial waste residues mainly have the following deficiencies: the quality of cement is not stable, and its strength is low, which cannot meet the needs of large-scale construction projects. Contents of the invention [0003] The purpose of the present invention is to provide a proces...
