Abstract
The special-purpose auxiliary material for concrete is formed from (by weight portion) 65-75 portions of mixed ash, 6-16 portions of slag powder, 3-7 portions of limestone powder, 2-6 portions of gypsum powder, 1-3 portions of lithium slag powder, 1-3 portions of rare earth micropowder and 4-8 portions of wollastonite powder. It is made up by adoting industrial waste materials, can be greatly substituted for cement, and the concrete prepared with it possesses high strnegth, good impervious property and frost resisting property, and its carbonization resistance can attain that the carbonization depth ratio is less than 95%, and its cost is low.
Description
Technical field
The present invention relates to material of construction, is a kind of concrete auxiliary material.
Background technology
The auxiliary material that uses in the present concrete, great majority are single components, for example flyash, silicon ash or ground slag powder etc.Their deficiency is: the one-level of flyash ash quantity is few, uses restrictedly, and ash in class III is then thicker relatively, and water consumption is more under the identical slump, and early strength is low; The output of silicon ash is few, costs an arm and a leg, and the concrete cost is increased by a relatively large margin; The energy consumption height of ground slag powder, and difficulty is big, production cost is high, and the application surface of engineering is narrower etc.Adopt these single auxiliary material concrete batchings, all can't make concrete reach higher performance.
Summary of the invention
The purpose of this invention is to provide a kind of concrete auxiliary material, it adopts the industrial waste preparation, can replace cement in a large number, makes the concrete strength height of preparation, and anti-permeability performance and good frost resistance, anti-carbonization ability reach the carbonation depth ratio less than 95%, the price root.
The present invention for achieving the above object, be achieved through the following technical solutions: concrete auxiliary material, by weight, its component and amount ranges are: combination ash 65-75 part, slag powders 6-16 part, limestone powder 3-7 part, terra alba 2-6 part, lithium slag powders 1-3 part, rare earth micro mist 1-3 part, silicon ash 4-8 part.
Described concrete auxiliary material, combination ash adopt one-level, secondary, three grades of flyash to mix by weight 1.5-2.5/6-7/0.5-1.5.
Described concrete auxiliary material, by weight, its component and amount ranges are: 70 parts of combination ash, 12 parts of slag powders, 5 parts of limestone powders, 2 parts of terra albas, 3 parts of lithium slag powders, 2 parts of rare earth micro mists, 8 parts of silicon ashes.
Described concrete auxiliary material, by weight, its component and amount ranges are: 75 parts of combination ash, 7 parts of slag powders, 3 parts of limestone powders, 5 parts of terra albas, 1 part of lithium slag powders, 3 parts of rare earth micro mists, 6 parts of silicon ashes.
Auxiliary material of the present invention, know to have following advantage through various tests: 50% replaces cement, water reducer 0.75%, during water consumption 170Kg, slump 230mm, workability is good; Intensity is good, compares with existing concrete, and 7 days intensity reaches 70%, 28 day intensity and reaches 100%, and impervious aspect ratio is less than 75%.Under condition, the test result carbonation depth compares less than 95%, and has anti-permeability performance preferably, and cost is low, draws materials extensively, can replace cement in a large number.
The described combination ash of auxiliary material of the present invention can be the mixture of first level flour coal ash and three grades of flyash, also can be the mixture of secondary and three grades of flyash, production technique of the present invention for one-level, secondary, three grades of flyash respectively by component and weight requirement mix, standby.Again with slag, Wingdale, gypsum, lithium slag, separated pulverizing, dryout, after mixing by above-mentioned component and weight requirement, adopt the pulverizer grinding to 450-750m
2/ Kg, last.By component weight of the present invention requirement, combination ash, rare earth micro mist, silicon ash are together sent into the pulverizer mix grinding evenly promptly becomes product of the present invention.
