Abstract
The invention relates to a low-alkaline accelerator and a preparation method thereof. The accelerator comprises sodium fluoride, thiocyanate, organic hydramine and mineral additive. The preparation method comprises the following steps: weighing all the components in proportion, putting the components into a mixing agitator, stirring and mixing the components uniformly so as to obtain the low-alkaline accelerator. The accelerator prepared by the method can be used for reducing dust, has strong adhesive strength, and also can be used for reducing falling ash.
Description
Technical field
The present invention relates to a kind of concrete admixture in building field, be specifically related to a kind of low alkali accelerating chemicals and preparation method thereof.
Background technology
Accelerating chemicals is a kind of admixture that can make the rapid setting and harden of concrete in concrete that mixes.Mixing a small amount of accelerating chemicals change can make concrete solidify at short notice, form in a short period of time enough intensity, to guarantee the requirement of special construction, reach the object of concrete rapid coagulation in repairing or roadway, it is indispensable additive in construction of shotcrete method.And the deficiency such as accelerating chemicals of the prior art has that dust is large, bonding force is little, alkali content is large, corrosion is hurted sb.'s feelings.
Summary of the invention
The object of this invention is to provide a kind of low alkali accelerating chemicals and preparation method thereof, by the prepared accelerating chemicals of the method, can reduce dust, and bonding force is large, ash is fallen in minimizing, and can use manpower and material resources sparingly etc., overcome deficiency of the prior art.
