Abstract

The present invention discloses a sprayed concrete setting accelerator. In the method, 35% of bauxite, 24% of sodium carbonate, 30% of limestone and 11% of coal are prepared into raw materials according to a weight ratio, pulverized and put in a high temperature furnace of 1250 DEG C to be calcined into alumina clinker, and 40 to 60% of alumina clinker and 40 to 60% of fluidized slag are pulverized into trituration after being stirred uniformly according to a weight ratio until the fineness is smaller than 15%. The sprayed concrete setting accelerator has the advantages that waste fluidized slag is utilized to change waste into valuables so as to reduce the environment pollution of the slag; simultaneously, because the alunite of the high temperature calcination is omitted, the electrical energy is saved, the production cost is reduced, and the later strength of the concrete is ensured.

Description

Shotcrete accelerator
Technical field
The present invention relates to a kind of Hardenfast, especially with the shotcrete accelerator that uses in the constructions such as mine, tunnel, subway.
Background technology
The accelerating chemicals of known sprayed concrete is to be added through blended materials such as the alunite of high-temperature calcination and alum mud, gypsum by plumbous oxygen grog to make, thereby cause concrete later strength lower, rebound degree is higher, can not adapt to construction process requirement, can not guarantee construction quality; Because of need high-temperature calcination alunite, increase power consumption simultaneously, caused the products production cost higher.
Summary of the invention
The objective of the invention is to provide a kind of shotcrete accelerator that utilizes the useless boiling furnace slag production of power plant, this accelerating chemicals greatly reduces production cost, has guaranteed the raising of construction quality.
The object of the present invention is achieved like this: by weight 35% bauxitic clay, 24% soda ash, 30% Wingdale, 11% coal are mixed with raw material, pulverize, enter 1250 ℃ of High Temperature Furnaces Heating Apparatuss and be sintered into aluminum oxide clinker, after stirring by weight boiling furnace slag with the aluminum oxide clinker of 40-60% and 40-60%, pulverize, fineness little 15% gets final product.
Boiling furnace slag is generated by the calcining of coal gangue through Fluidized Bed Boiler, and its pozzolanic activity composition is more, Al 2O 3Content reaches 30% (and alunite only is 18%), thereby makes the agglomerative time further shorten, and under the effect of pozzolanic activity, has guaranteed concrete later strength.
Advantage of the present invention: utilize the useless boiling furnace slag of power plant, turn waste into wealth, reduced the pollution of slag to environment; Because of having saved the alunite of high-temperature calcination, save electric energy simultaneously, reduced production cost, guaranteed concrete later strength.
Embodiment
35 kilograms bauxitic clays, 24 kilograms of soda ash, 30 kilograms Wingdale, 11 kilograms coal are mixed with raw material, through 1.5 meters large-size ball mills, wear into fineness less than 15% powder, become through pan-pelletizer group that about 15mm's is spherical, advance blast furnace high-temperature calcination (furnace temperature is 1250 ℃), generate aluminum oxide clinker, get 50 kilograms aluminum oxide clinker and 50 kilograms boiling furnace slag, enter 1.5 meters ball mill pulverizes after stirring, fineness little 15% gets final product.Water ratio is starched initial set time of coagulation less than 3 minutes only less than 2%, and final set was less than 5 minutes, and ultimate compression strength was greater than 10Mpa in 1 day.

Claims (1)
