Abstract
A kind of pulverized fuel ash cement exciting agent.It is mixed by weight by following components, 15 25 parts of flyash, alunite 10 30 parts, 15 30 parts of aluminum sulfate, 10 20 parts of calcium chloride, and 0.5 1.5 parts of activator mixes.The present invention can make flyash addition in cement high, therefore, it is possible to well can effectively utilize a large amount of flyash, can reach Portland cement to operating characteristics, the requirement of the early strength of cement concrete after the mobile performance of complex cement and the in use molding time of cement and molding in the construction of building simultaneously.
Description
Technical field
The present invention relates to cement technology field, be specifically related to a kind of pulverized fuel ash cement exciting agent.
Background technology
In existing pulverized fuel ash cement, the incorporation of flyash is not the highest, and reason is to mix flyash in a large number can cause
The early strength of the pulverized fuel ash cement of rear formation substantially reduces.Now due to a large amount of uses of coal, produce after coal burning
A large amount of flyash urgently process, simultaneously because containing substantial amounts of aluminium oxide Al 2O3 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 in use water
The molding time of mud meets cement with becoming to be combined, and cement mortar plays very important effect wherein.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, it is provided that a kind of pulverized fuel ash cement exciting agent.
In order to solve above-mentioned technical problem, the invention provides following technical scheme: a kind of pulverized fuel ash cement exciting agent,
By flyash 15-25 part, alunite 10-30 part, aluminum sulfate 15-30 part, calcium chloride 10-20 part, activator 0.5-1.5 part mixes
Form.
The present invention can make flyash addition in cement high, therefore, it is possible to well can effectively utilize a large amount of fine coal
Ash, can reach simultaneously Portland cement to operating characteristics, in the construction of building complex cement mobile performance and
The in use requirement of the early strength of the cement concrete after the molding time of cement and molding.
Detailed description of the invention
Embodiment 1:
By 15 parts of flyash, alunite 10 parts, 25 parts of aluminum sulfate, calcium chloride 10, the stirring of 0.5 part of activator, it is mixed to prepare and excites
Agent.
Embodiment 2:
By 25 parts of flyash, alunite 30,15 parts of aluminum sulfate, calcium chloride 20, the stirring of 1.5 parts of activator, it is mixed to prepare exciting agent.
Embodiment 3:
By 20 parts of flyash, alunite 25,30 parts of aluminum sulfate, calcium chloride 15, the stirring of 1 part of activator, it is mixed to prepare exciting agent.
Claims (1)
