Description
Technical field
The present invention relates to a kind of auxiliary for material of construction, belong to the concrete admixture class, be specifically related to a kind of concrete viscosity conditioning agent that can significantly reduce high-strength or super high strength concrete viscosity.
Background technology
Along with the civil engineering work scale constantly enlarges, scientific and technological level improves constantly, some high-rise long spans, the continuous appearance of the Important building that specific function requires is arranged, as construction of skyscraper, super-span bridge and huge water-control project etc., require concrete must have higher intensity, better weather resistance, more excellent stability, these demands have facilitated concrete progressively to develop to high-performance and even very-high performance direction from common.The raising of concrete strength mainly recently realizes by reducing glue, and this has also caused concrete viscosity larger, causes a series of construction problems such as concrete-agitating, transportation, pumping, limited to a great extent high-strength and propagation and employment super high strength concrete.High-strength particularly super high strength concrete is used for prefabricated components basically at present, and the application example of large scale structure engineering does not substantially also have, let alone pumping construction.
How to reduce concrete viscosity and become key issue high-strength and the super high strength concrete development.From high-strength and composition and preparation method super high strength concrete, present adoptable viscosity reducing process is mainly to carry out from organic admixture and adulterant two aspects.Yet still unintelligible to the concrete viscosity mechanism of action about water reducer, the research and development of organic viscosity-depression agent also do not occur the Patents of the organic viscosity-depression agent of concrete at present still without breakthrough; And the adulterant aspect does not have to occur patent or article about the concrete viscosity-depression agent equally, mainly to improve the concrete work performance by mixing a large amount of flyash at present, mix as everyone knows that flyash can reduce concrete viscosity but larger to concrete intensity effect, totally unfavorable for lifting high-strength or ultra-high performance concrete intensity, and fly ash is also day by day deficient, and the novel viscosity modifier of therefore needing the development excellent property badly reduces the viscosity of high-strength or super high strength concrete.
Summary of the invention
The objective of the invention is for present high-strength or super high strength concrete viscosity large, construction is difficult shortcoming, a kind of high-strength or super high strength concrete viscosity modifier is proposed, can effectively lower concrete viscosity, and have that consumption is few, cost is low and on intensity without characteristics such as impacts.
The applicant finds after deliberation: particle surface water film thickness principal reaction water consumption, packing density and the total specific surface area three aspects: of particle information; Surface water thicknesses of layers and concrete viscosity are closely related, and particle surface water film thickness is larger, and concrete viscosity is lower; Major cause high-strength or that super high strength concrete viscosity is large is that the particle Interaction Force is large because low water binder ratio has caused particle surface water film thickness little.
Based on above-mentioned research, the present invention maximizes viscosity-reducing machine with water film thickness and is made as the basis, silicon ash, superfine powder and flyash by admixture different-grain diameter scope are optimized the gelling material grain composition, make packing density increase and can not cause that the surface-area of gelling material increases substantially, and has namely increased the water layer thickness of particle surface as far as possible; And because superfine powder can improve the admixture adsorption efficiency, reduce the admixture consumption, reduce solution viscosity in concrete, and because pattern effect and the surface charge effect of powder granule reduced the particle Interaction Force, caused concrete viscosity further to reduce.Because the particle packing degree of compactness increases, this viscosity modifier can't cause the reduction of concrete strength.
Concrete technical scheme of the present invention is as follows:
A kind of high-strength or super high strength concrete viscosity modifier is made of by mass percentage following material:
Silicon ash 2% ~ 10%;
Flyash 10%-20%;
Exciting agent 2% ~ 3%;
Superfine powder 67% ~ 86%.
The median size of described silicon ash is 0.1 μ m～0.3 μ m, silicon ash in this particle size range is other intergranular spaces such as filling concrete, flyash and fine powder effectively, improve the matrix density, be conducive to the release of free water in the space and the raising of concrete strength, in addition the high pozzolanic activity of silicon ash can further improve concrete strength.
The fineness of described flyash is preferably 45 μ m square hole sieve screen over-size＜10%, and its fineness meets the requirement of I level flyash, has not only optimized grain composition, and because the ball effect can reduce intergranular friction power, improves concrete rheological property.
Described exciting agent is selected from a kind of in calcium hydroxide, sodium carbonate, calcium oxide or calcium sulfate, and above-mentioned exciting agent can significantly improve the adulterant activity, improves concrete strength.
One or more arbitrary proportions that described superfine powder is selected from super finely ground slag, limestone powder, silica powder mix; Above-mentioned powder has good hydrophilic property, the characteristics of easily disperseing, and can significantly improve the water reducer adsorption efficiency, effectively improve concrete rheological property.
The median size of described superfine powder is 2 μ m～10 μ m, and its particle diameter is between silicon ash and cement granules, but the Effective Regulation grain composition, and this particle size range superfine powder is on the impact of water reducer adsorption efficiency significantly.
The present invention optimizes the gelling material grain composition by silicon ash, superfine powder and the flyash of the above-mentioned different-grain diameter scope of admixture, makes packing density increase and can not cause that the surface-area of gelling material increases substantially.
Viscosity modifier of the present invention only needs each component materials is mixed to get final product, and prepares simplely, is convenient to promote the use of.
During use, the quality such as high-strength or super high strength concrete viscosity modifier of the present invention replace cement and join in concrete gel material, and its add-on accounts for 10% ~ 30% of concrete gel material total mass, can make concrete viscosity reduce by 25% ~ 60%.
The present invention improves packing density by optimizing the gelling material grain composition, increased the water layer thickness of gelling system particle surface, improved the adsorption efficiency of admixture, reduce the consumption of admixture, reduced solution viscosity in concrete, and because pattern effect and the surface charge effect of powder granule reduced the particle Interaction Force, and then caused the concrete viscosity reduction.Can improve packing density because viscosity modifier of the present invention contains sub-micron-powder, and superfine powder has certain activity, therefore mixing this viscosity modifier can not reduce concrete strength.Viscosity modifier of the present invention is equally applicable to the low water binder ratio mortar.
