Description
Technical field
The present invention relates to a kind of high-performance assembled architecture reinforced bar sleeve grouting material, belong to building material technical field.
Background technology
At present, as promotion efficiency of the country to assembled architecture increases, the application of grouting material is more and more, presently, there are
Most of grouting material raw material mainly by cement, quartz sand, swelling agent, retarder, water reducer composition, such a grouting material resistance to compression
Intensity >=85MPa, grouting material specification basic performance can be reached, but vertical expansion ratio can not reach with leading indicators such as fluidities
To standard requirement, particularly fluidity, most domestic grouting materials are all unable to reach standard requirement, occurred as soon as after 10min solidifying
Solid fraction state.In order to reach specification strength criterion, prior art improves grouting material usually using quartz sand as one of raw material
Intensity, but because quartz sand price itself is higher, and as one of grouting material raw material, its dosage is larger, causes synthesis to fill
Cost of sizing agent increase, if also needing addition slag or steel fibre, cost higher.Meanwhile grouting material to fluidity requirement also compared with
Height, most grouting materials only add retarder and are unable to reach code requirement, must also add the additives such as adjustable solidification agent to increase grouting material
Fluidity, reaches standard requirement, and the use of complicated additive further increases grouting material synthesis cost, makes grouting material in reality
Application in construction is a greater impact.
In the prior art, also occurring still can not be up to standard using quartz sand, and must be added to slag or steel fibre carries
High intensity ability situation up to standard, forms a small amount of property grouting material.Such as：A kind of " cement-based ultra-high strength ungauged regions grouting
Material（CN101921086A）" by adding Stainless-steel fibre grouting material intensity, 28d compression strength is reached more than 120MPa；It is " high
Anti- folding strength cement-based grouting material（CN102503318A）" by adding the raising grouting material rupture strength such as gypsum and mineral fibres, make
Rupture strength reaches more than 15MPa.As a whole, prior art is primarily present the problem of two aspects, and one is reaching for intensity
Mark, one be cost reduction, so as to cause the greatest differences of domestic and international grouting material price and performance.External most grouting materials can
To reach standard requirement, but price is average at 6000 yuan/ton, domestic most averagely as little as 1500 yuan/ton, but matter of grouting material prices
Amount can not be guaranteed.
The content of the invention
The technical problem to be solved in the present invention is high for standard compliant grouting material price at present and the grouting of low price
Expect the situation that quality can not be up to standard, propose a kind of high-performance assembled architecture reinforced bar sleeve grouting material, replaced using mountain sand or river sand
For quartz sand as aggregate, while grouting material intensity is ensured, its production cost is greatly reduced.
In order to solve the above technical problems, the present invention supplies a kind of high-performance assembled architecture reinforced bar sleeve grouting material, its quality
It is than component：Cement 80-100 parts, quartz sand 0-80 parts, mountain sand or river sand 10-100 parts, swelling agent 5-15 parts, retarder 0-1
Part, water reducer 0.5-3 parts, defoamer 0-1 parts, slag 15-80 parts；Each component dosage with specific reference to be actually needed determine.
The quartz sand, mountain sand or river sand, the granularity of steel-making slag powder are the mesh of 400 mesh -1000, true with specific reference to being actually needed
It is fixed, meet bar connecting sleeve grouting material standard related request.
The swelling agent, retarder, water reducer, defoamer, which use, meets the normal of Technical code for application of admixture in concrete
Gauge material.Swelling agent can use gypsum, MgO, calcium sulphoaluminate class, calcium oxide etc., and retarder and water reducer can use sugar calcium, wood
Quality sulfoacid calcium, citric acid, zinc salt, phosphate etc., defoamer can use colophonium pyrolytic polymer, petroleum sulfonate etc..
The preparation method of the high-performance assembled architecture reinforced bar sleeve grouting material is：Under normal temperature, normal pressure, first take in proportion
Cement, quartz sand, mountain sand or river sand, slag, it is mixed uniformly；Then the 12%-14% of mixture weight is pressed, is slowly added to water
And stir, swelling agent, retarder, water reducer and defoamer are slowly added in whipping process in proportion, treat material stirring uniformly into
It can be used after slurry.
Because river sand is low compared with quartz sand with mountain sand surface-active, can not be taken in reinforced bar sleeve grouting material preparation process
All materials are mixed into the prior art for adding water to mix and stir after dry powder in proportion again, and need first mix cement and aggregate, Ran Houzai
Bian Jiashui stirrings side adds additive, to increase the surface-active of sand, and makes each material contact evenly, improves last grouting material
Performance.
800-900 yuan/ton of quartz sand market price, 80-100 yuan/ton of river sand market price, mountain sand market price 100-150 members/
Ton.The present invention partly or entirely instead of quartz sand, and is passed through using natural sands such as the river sand very low compared with quartz sand price, mountain sand
Industrial waste steel dreg is added to improve the compression strength of grouting material, offsets due to the replacement of natural sand and grouting material intensity drop occurs
Low phenomenon, grouting material intensity is set to reach standard requirement, so as to which cost of sizing agent is greatly lowered.Industrial waste slag only need through
Cross simple cleaning to use with screening, be not only advantageous to environmental protection, and handling process is simple, relatively using quartz sand without using steel
Slag phase ratio, cost will not also increase.
Grouting material demand of technical standard initial flow degree >=300mm, 30min fluidity >=260mm, 28d compression strength >=
85MPa, 3h vertical expansion ratio >=0.02%, 24h and 3h vertical expansion ratios 0.02%-0.50%.In addition to retarder, prior art
In also need to add the additive such as adjustable solidification agent to meet the requirement of grouting material fluidity, and additive price general charged is more expensive, complicated outer
Add the use of agent larger negative effect can be caused to the cost of grouting material, the present invention reaches reduction by the optimization to match ratio
The purpose that complicated additive uses, using only retarder or without using retarder grouting material can be made to reach wanting for standard criterion
Ask.
The present invention partly or entirely replaces quartz sand by using the river sand or mountain sand of low cost, reduces complicated additive
Use, the purpose for adding three kinds of technical measures of industrial waste steel dreg to reach retention property, reduce cost, grouting material can kept
On the premise of property indices reach standard criterion requirement, significantly reduce the cost of grouting material, price can be reduced to 4000 yuan/
Ton or so.
