Description
Technical field
The present invention relates to building material field more particularly to a kind of low temperature bar connecting high performance grouting material and its preparations
Method.
Background technology
Housing industrialization is the modern times advanced industrialization mould that dwelling construction is carried out using industrialization prefabricated concrete structure
Formula.Housing industrialization is promoted to be conducive to improve the labor productivity of dwelling construction, Residence Design is promoted to become more meticulous with what is built, is carried
Total quality and the energy-saving and emission-reduction for rising house are horizontal, push the sustainable development of dwelling construction, can promote new economic growth side
Formula changes and industrial upgrading, is one of only way of real estate and construction industry development.In recent years, assembled architecture correlation skill
Art China is rapidly developed.Assembled architecture is quickly grown, but there is also the factor for much restricting its development, wherein assembling
Between formula component is one of key factor in succession.Traditional bar splicing obviously can not meet the need of prefabricated components assembling
Will, because the usual lap of splice of reinforcing bar is 35d, at this moment the preset clearance between component is excessive, and cast-in-place part greatly increases, and causes
Precast concrete factorial praluction loses meaning.Welding procedure is also required between component there are larger manual operation gap,
And weld interval is long, the supporting of component is difficult.Consider various pros and cons, mechanical splice bar connecting is done as best solution
One of method.At present mechanical splice in cast-in-place concrete mainly based on straight thread connector, cold extruded joint, taper thread joint,
Wherein being threadedly coupled has the characteristics of connection speed is fast and intensity is high, but they generally need certain operating space and to being connected
The relative position requirement of reinforcing bar is high so that and operability is greatly reduced, and the construction of these types of connection mode is also complex, and
And bar connecting must be completed before concrete is poured into a mould, it is not suitable for the fabricated construction of precast concrete.For this
Special circumstances produce new bar connecting system --- and reinforced bar sleeve grouting connector, anti-seismic performance is reliable, easy construction,
It can shorten the construction period, suitable for the connection of the Ribbed Bar of diameter of different sizes, more important point is that it has been truly realized structure
Slitless connection between part solves the problems, such as the connection of precast concrete prefabricated member.At present, reinforced bar sleeve grouting technique has been
Through the main interconnection technique for becoming the components such as precast shear wall, frame column, beam.
The grouting of assembled architecture member reinforcing steel bar sleeve is connected as concealed work, and the quality of grouting quality directly influences structure
Safety, the grouting duration directly affects the structure construction duration, and then influences engineering overall cost.Due to lacking low temperature season construction
Grouting material product and corresponding construction technology, the assembled architecture of northern China wide geographic area need to be forced to stop work in winter, sternly
Advantage of the assembled architecture with respect to traditional construction mode rapid construction is weakened again.
According to《Reinforced bar sleeve grouting connection application technology regulation》JGJ355-2015 provides that when sleeve grouting construction is in the milk
Expect that temperature in use should be not less than 5 DEG C.The longer area construction of this low temperature season, the effective erector of prefabricated member in Beijing
Phase greatly shorten it is short, therefore study be suitable for low temperature season construction ultra early-strength grouting material have very big realistic meaning.Mesh
Before, the external grouting material for only having Japan Electric Chemical Co., Ltd. to carry out 5 DEG C or so research, the country, which thinks to reach, builds luxuriant development in science and technology
Zhu Qinghua of Co., Ltd etc. has studied the application of low subzero temperature condition lower sleeve grouting material, but it requires sleeve spot temperature 0
DEG C or more, still there is larger restriction.
Invention content
In view of the deficiencies of the prior art, an object of the present invention, which is to provide, a kind of prepares low temperature（At -5 DEG C to 10 DEG C）Steel
The method of muscle connection high performance grouting material meets the construction requirement of bar connecting sleeve grouting material at low ambient temperatures.
To solve the above problems, the technical solution adopted by the present invention is：A kind of low temperature bar connecting high performance grouting material
Be cementitious material, mineral admixture, graded aggregate, water-reducing agent, plastic expansion agent, additive mixture dry powder add water stir and
Into.
Wherein described cementitious material is portland cement, sulphate aluminium cement, high alumina cement and high belite aluminium sulfate
The one or two of cement or three kinds or four kinds, strength grade 32.5 to 82.5.
The graded aggregate is one or both of quartz sand, diamond dust, Machine-made Sand, corundum, silicon carbide etc. or three kinds
Or four kinds or five kinds.
The water-reducing agent is the high performance water reducing agent of polyocarboxy acid of powdery.
The mineral admixture for silicon ash, metakaolin, microballon, miberal powder, one kind in superfined flyash or or two kinds or
Three kinds or four kinds or five kinds
The plastic expansion agent is a kind of organic compounds containing nitrogen.
Preparation method is that low temperature bar connecting high performance grouting material dry powder is added water using ratio of water to material as 0.11 ~ 0.16
Ratio stirs.
Compared with the prior art, the present invention has the following advantages：
1）Grouting material good fluidity of the present invention, self compacting ability are strong；
2）Grouting material early strength of the present invention is high, volume microdilatancy, later strength not retraction, and endurance quality is good；
3）Grouting material of the present invention can meet under -5 DEG C to 10 DEG C construction environments《Reinforced bar sleeve grouting connection application technology regulation》
The requirement of JG/T408-2013 standards.
Grouting material of the present invention meets《Reinforced bar sleeve grouting connection application technology regulation》JGJ 355-2015 requirements, are realized
The all-weather construction of straight screw sleeve connection connector.
