Description
Technical field
The present invention relates to a kind of very-high performance mortar for building puzzle joint.
Background technology
By matrix material in masonry structure（Such as the building block of brick, stone material and concrete segment or other materials）Bonding is got up
Mortar be referred to as masonry mortar.Because matrix material is to lean on mortar bonding into a firm entirety and transmit load, therefore will
Asking should have certain adhesion strength between mortar and matrix material.Generally, the compression strength of masonry mortar is higher, itself and matrix it
Between adhesion strength it is then higher.Adhesion strength is not enough, will seriously reduce intensity, globality, durability and the antidetonation of whole masonry
Property.In the rural area and villages and small towns of China's southeastern coast, substantial amounts of stone masonry building is there is.Due to early stage barnacle body building construction
The building method that slurry is got rid of in laid dry is carried out using ordinary mortar mostly, the closely knit plumpness of mortar in puzzle joint is relatively low, and caking property is poor,
Mortar silty or weathering are more serious so that puzzle joint turns into the Main Weak Links of structure.Existing most of barnacle body rooms
Overall performance and shock resistance are built in room obvious deficiency.
The content of the invention
The present invention makes improvement for the problem that above-mentioned prior art is present, i.e., the technical problems to be solved by the invention are
A kind of very-high performance mortar for building puzzle joint is provided, with high resistance to compression and rupture strength, the packing of superelevation, good
Durability and viscosity is poly- and preferable ductility.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of very-high performance sand for building puzzle joint
Slurry, including river sand or quartz sand as fine aggregate, the cement as Binder Materials and active mineral admixture and efficiently outer
Additive, high intensity micro steel fiber and water, it is the fine aggregate, cement, active mineral admixture, efficient external additive, high-strength
Degree micro steel fiber, the mass ratio of water are（30.4~42.3）kg：（30.9~41.2）kg：（3.8~18.6）kg：（3.2~15.1）
kg：（0~5）kg：（5.4~18.4）kg.
Further, the average grain diameter of the river sand or quartz sand is 0.315mm~0.63mm.
Further, the active mineral admixture is SiO2More than or equal to 90%, particle diameter be 0.1~0.2 μm silicon ash and
Grade is II grade, 45 μm of flyash of screen over-size≤25% of side's sieve of fineness requirement.
Further, the tensile strength >=2860MPa of the high intensity micro steel fiber, 12~14mm of length, diameter
0.18~0.22mm.
Further, the efficient additive includes high efficiency water reducing agent, coagulant, adhesion agent and swelling agent.
Further, the water-reducing rate of the high efficiency water reducing agent is more than or equal to 25%, it is possible to reduce water consumption, reduces water ash
Than so as to reduce Mortar shrinkage cracking；Coagulant can reduce gel time；Adhesion agent can improve the cohesive force at interface；Swelling agent
Can be used to compensate the contraction of mortar, improve volume stability
Further, described cement is Portland cement, and preferably high-quality, strength grade are 52.5 cement
Compared with prior art, the invention has the advantages that：Due to active mineral admixture and the group of efficient additive
Cooperation is used, and reduces the porosity of mortar, so as to reach the purpose of superhigh intensity, makes up the not enough shortcoming of puzzle joint intensity.Due to building
Itself compression strength for stitching mortar is big, the frame strength that puzzle joint is formed also than larger, so as to significantly improve the whole of masonry structure
Body performance and anti-seismic performance.Meanwhile, use the particle diameter of each component to be optimized by closestpacking principle, can increase substantially
The packing of mortar, effectively makes up the shortcoming of puzzle joint easy-weathering, and then improve the durability of puzzle joint.The mortar in gel process
Drying shrinkage will not occur, tension will not be produced inside basal body structure, so as to improve the adhesive property between mortar and matrix.This surpasses
High Performance Mortar can act also as the replacement of existing stone masonry structure puzzle joint in addition to can be as the masonry mortar of newly-built masonry structure
Material, so as to reinforce stone masonry structure, extends its service life, with good mechanical property and economic benefit.
With specific embodiment, the present invention will be further described in detail below.
Specific embodiment
Embodiment one：As a example by spreading slurry processes, raw materials used and each component mass percent is referring to table（1）：
Table（1）Each component mass percent
In the present embodiment, the match ratio of the very-high performance mortar can carry out appropriate adjustment according to the situation of job site, apply
Work is more simple.
In the present embodiment, in the paving slurry processes, should ensure that the plumpness of puzzle joint mortar reaches more than 90%, in building process
In should strictly control each to build layer flatness and puzzle joint width by laying bricks or stones.
In the present embodiment, the resistance to compression that can significantly improve bearing masonry post using the very-high performance mortar in example 1 carries energy
Power, close to the intensity of building block；The larger brittle break degree for improving masonry structure, and the shearing resistance of masonry structure is improved to a certain degree
Bearing capacity.
Embodiment two：As puzzle joint reinforcement mortar.
By taking the bearing wall structure of existing barnacle body as an example, the original mortar of puzzle joint is replaced and mended using reinforcement mortar
By force.Puzzle joint reinforcement mortar uses pressure grout method.First, the pre-buried pad in wall puzzle joint（Pad spacing is according to actual conditions
Depending on）, original mortar is understood using giant；Secondly, two-sided jointing is carried out to wall；Finally, prepare grout nipple and carry out
Grouting.Raw materials used and each component mass percent is referring to table（2）：
Table（2）Each component mass percent
In the present embodiment, to meet the general requirement using pressure grouting, such as thickness of wall body not less than 240mm, wall it is vertical
Deviation is not more than 10mm etc..Answer subregion, remove original mortar stage by stage, should not be in same time, same stage by whole face wall body
Puzzle joint all remove.
In the present embodiment, boring aperture needed for grouting will be slightly larger than grout nipple, and slag end should first rinse well in hole, fixed to fill
Slurry mouth is simultaneously compacted floating.When thickness of wall body is more than 370mm, wall two sides should all set grout nipple using two-sided grouting.
In the present embodiment, grouting pressure should be controlled in 0.2 ~ 0.25MPa, and filling process should be carried out at twice.For the first time by
Under be up hole-specifically in the milk, be spaced about 30 ~ 60 min.Mend heavy grouting from top to bottom for the second time.According to the mortar feelings that slurry outlet flows out
Condition come judge grouting saturation degree whether meet requirement.
In the present embodiment, grouting material should meet the finger such as fluidity, expansion rate, early stage and final strength and setting time
Mark is required.
In the present embodiment, after being replaced reinforcement by using the reinforcement mortar, can significantly improve mortar and building block it
Between cohesive force, so as to improve the cracking load of wall, ductility and overall performance.
Embodiment three：Used as the very-high performance mortar of wall reinforcement, raw materials used and each component mass percent is shown in Table
