Abstract
The invention discloses a kind of accelerator for cement slurry, belong to building field.The present invention is using Patent alum and calcium oxide as raw material, by high speed shear, prepares and promotees solidifying substance with cement；Using lithium slag as raw material, it is handled using microwave, it is set to contain more free lithium salts, etc. the condensation that can promote cement concrete, shorten the time of initial set, aluminium oxide, calcium sulfate in lithium slag can also react generation hydrated calcium aluminate sulfate, early strength can be improved, it is compound to add bamboo fibre progress, in the incorporation of bamboo fiber, volume contraction stress is resolved to which crackle is reduced, and cement-based mortar increases flexural strength with bamboo fiber volume and increases, cracking resistance, the compression strength of later stage cement mortar are improved, Cement Quality is improved.
Description
Technical field
The invention belongs to building fields, and in particular to a kind of accelerator for cement slurry.
Background technology
Coagulant is a kind of additive in building mortar, building concrete, also can be used as oil, natural gas extraction
Processing aid.Downcomer, thermal insulation layer particularly suitable for cement products, cement prefab and cement road repairing etc. will seek quickness
Rapid hardening is solid and accelerates project of the mold using turnover.Have the characteristics that cement products rapid hardening, promote solidifying, early strong, good operation performance,
The setting rate of cement can be dramatically speeded up, the early strength of setting time extra-high cement products is shortened.
Domestic main coagulant at present is all inorganic salts, and the main component of most of coagulant is sodium aluminate, other
Inorganic salts with blood coagulation enhancing effect include sodium carbonate, calcium aluminate, fluorine calcium chlorate, magnesium fluosilicate, sodium metasilicate, prodan, chlorination
Ferrous, aluminum sulfate and alchlor etc..Wherein, calcium chloride is more common accelerator for cement slurry, has cheap, blood coagulation enhancing effect
The advantages that good, but accelerator for cement slurry can be such that cement mortar thickening, drilling fluid rheology declines at present, or even there is " dodging solidifying " phenomenon.
Therefore, it produces and a kind of efficient promote solidifying and have the prodigious market demand to coagulant of the drilling fluid rheology without influence.
Invention content
The technical problems to be solved by the invention：Cement mortar can be made to increase based on calcium chloride for current accelerator for cement slurry
Thick, drilling fluid rheology declines, or even occurs dodging solidifying problem, provides a kind of accelerator for cement slurry.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of accelerator for cement slurry, which is characterized in that include following component, 2 ~ 4 parts of ethyl celluloses, 15 ~ 20 according to the mass fraction
