Abstract

A processing method of a fly ash cement exciting agent is prepared through the following steps: mixing 15-25 parts by weight of fly ash, 10-30 parts by weight of alunite, 15-30 parts by weight of aluminum sulfate, 10-20 parts by weight of calcium chloride and 0.5-1.5 parts by weight of an exciting agent, crushing mixed materials, and stirring the crushed materials. The fly ash cement exciting agent allows the addition amount of fly ash in cement to be high, so a large amount of fly ash is highly and effectively used, and ordinary portland cement's requirements of the operating performance, the fluidity of composite cement in construction of buildings, the forming time of cement in use and the early stage strength of formed cement concrete are reached.

Description

A kind of pulverized fuel ash cement exciting agent processing method
Technical field
The present invention relates to cement technology field is and in particular to a kind of pulverized fuel ash cement exciting agent processing method.
Background technology
In existing pulverized fuel ash cement, the incorporation of flyash is not very high, and reason is to mix flyash in a large number can lead to The early strength of the pulverized fuel ash cement being formed afterwards substantially reduces.Now due to a large amount of uses of coal, produce after coal burning A large amount of flyash are urgently processed, simultaneously because containing substantial amounts of aluminium oxide al2o3 and sulfur oxide sio2 in flyash, can affect The operating characteristics of the complex cement after configuration, in the construction of building the mobile performance of complex cement and water in use The molding time of mud meets cement with becoming to be combined, and cement mortar plays very important effect wherein.
Content of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of pulverized fuel ash cement exciting agent to add Work method.
In order to solve above-mentioned technical problem, the invention provides following technical scheme: a kind of pulverized fuel ash cement exciting agent Processing method, first weighs flyash and carries out pulverizing, screens, and then presses flyash 15-25 part, alunite 10-30 part, aluminum sulfate 15-30 part, calcium chloride 10-20 part, activator 0.5-1.5 part carries out mixing, pulverizes, stirs prepared exciting agent.
The present invention can make in cement flyash addition high, therefore, it is possible to well being capable of a large amount of fine coal of effectively utilizes Ash, can reach simultaneously Portland cement to operating characteristics, in the construction of building the mobile performance of complex cement and The requirement of the early strength of cement concrete after the molding time of cement and molding in use.
Specific embodiment
Embodiment 1:
First weigh flyash to carry out pulverizing, screen, then press 15 parts of flyash, 10 parts of alunite, 25 parts of aluminum sulfate, calcium chloride 10,0.5 part of activator carries out mixing, pulverizes, stirs prepared exciting agent.
Embodiment 2:
First weigh flyash to carry out pulverizing, screen, then press 25 parts of flyash, alunite 30,15 parts of aluminum sulfate, calcium chloride 20, 1.5 parts of activator carries out mixing, pulverizes, stirs prepared exciting agent.
Embodiment 3:
First weigh flyash to carry out pulverizing, screen, then press 20 parts of flyash, alunite 25,30 parts of aluminum sulfate, calcium chloride 15, 1 part of activator carries out mixing, pulverizes, stirs prepared exciting agent.
