Embodiment Construction

[0025] The improved cement quick-setting agent preparation method is characterized in that: comprising steps:

[0026] The first step, mixed calcination of raw materials: take 28.8% of bauxite, 40.1% of limestone, 21% of soda ash, and 10.1% of raw coal for mixed calcination to make alumina clinker, and the calcination temperature is 900-1200°C , the duration of calcination is 60-80 minutes; adopt new clean furnace calcination technology, complete set of environmental protection facilities, mechanical automation production process, high efficiency, low consumption, high quality and stable product quality;

[0027] The second step, mixed grinding: get the above-mentioned fired alumina clinker and industrial coal cinder to carry out mixed grinding, wherein 42% of alumina clinker and 58% of industrial coal cinder are made into the prior art cement quick-setting agent, and the mixed grinding time It lasts for 20-40 minutes, adopts computer automatic batching, ￠1.83×7m ball mill con...

Abstract

The invention relates to an improved manufacture method of cement accelerator, which comprises the following steps: step I, raw material mix calcination: carrying out mix calcination on 28.8% of bauxite, 40.1% of limestone, 21% of soda ash and 10.1% of raw coal to obtain a aluminum oxygen chamotte; step II, mix grinding: taking calcined aluminum oxygen chamotte and industrial coal cinder to carry out mix grinding to obtain a cement accelerator in the prior art; and step III: adding polyacrylamide and redispersible emulsion powder in proportion in the cement accelerator in the prior art. By adopting the method in the invention, the cement accelerator prepared improves the caking property of the concrete, enables the concrete to have enough moisture for conservation, changes the brittleness of the concrete, and enables the sprayed concrete to have a favorable anti-permeability, meanwhile increases the bond force of the sprayed concrete and the base course, and increases the stretching bonding strength of the base course.

Description

technical field [0001] The invention relates to an improved preparation method of cement quick-setting agent. Background technique [0002] The existing production method of the quick-setting agent is to use bauxite, limestone, soda ash (caustic soda), and coal to calcinate through a reasonable formula, and then burn it into alumina clinker, and then mix and grind the clinker with the mixed material in proportion , The product that draws is exactly prior art cement quick-setting agent. Its process is raw material batching - raw material grinding - calcining - clinker and mixed material grinding - packaging and storage. [0003] At present, the typical production of cement quick-setting agent in China is earth kiln production, which is extremely backward. Since there is no production license system for accelerators and the market access is simple, the current production processes and technologies of accelerators vary widely. [0004] Accelerator is mainly used for sprayed ...
