Part, it is 1-4 parts sugared.Since water content is higher, increase cement fluidity, and auxiliary improves the mobility of cement with sugar,
It is used cooperatively by addition Nacl, compound hydramine, so that the cement is able to maintain some strength in the higher situation of mobility,
To adapt to the requirement for producing and constructing；Each component makes each component play self performance by the effect of glycerol, and it is each at point it
Between interact, improve mill efficiency, improve yield, preferably promotion cement performance.
Further, 50 parts of water, 2 parts of Nacl, 4 parts of dodium thiosulfate, 4 parts of sodium nitrite, 6 parts of urea, 20 parts of compound hydramine,
12 parts of glycerol, 2 parts of sugar keeps cement fluidity more preferable, and has better intensity, better adapts to the requirement for producing and constructing,
And mill efficiency is improved, yield is improved, preferably promotion concrete performance.
Preferably, the incorporation of the aluminium slag powder grinding aid is the 0.02~0.05% of aluminium slag powder total amount to be ground, with aluminium
Ground-slag plays a role jointly, and aluminium slag powder is made to have good service performance, keeps cement fluidity more preferable, and has preferably strong
Degree.
Further, the incorporation of the aluminium slag powder grinding aid is the 0.05% of aluminium slag powder total amount to be ground, total with aluminium slag powder
With playing a role, so that aluminium slag powder is had good service performance, keep cement fluidity more preferable, and there is better intensity.
The preparation method of the aluminium slag powder grinding aid of the present invention for improving mobility, comprising the following steps: according to successive
Sequence sequentially adds water, Nacl, dodium thiosulfate, sodium nitrite, urea, compound hydramine, glycerol, sugar, and one component of every addition is extremely
After completely dissolution, next component is added.Each component can be made preferably to play a role, and aluminium slag powder is made to have good make
Use performance.
The present invention compared with the existing technology has the following advantages that and effect: since water content is higher, increasing cement fluidity
Add, and cooperate auxiliary to improve the mobility of cement from sugar, by adding Nacl, compound hydramine is used cooperatively, and makes cement
It is able to maintain some strength in the higher situation of mobility, to adapt to the requirement for producing and constructing；Each component passes through glycerol
Effect makes each component play self performance, and interacts between each ingredient, improves mill efficiency, improves yield, preferably
Promote cement performance；It plays a role jointly with aluminium slag powder, aluminium slag powder is made to have good service performance.
