Description
Technical field
The invention belongs to rehabilitating historic building technical fields, and in particular to a kind of ancient building repair with reinforce composite material and its
Construction method.
Background technique
Structural member in ancient building is artificially trampled or is touched since the built time is longer, while by erosion by wind and rain and for a long time
Easily there is crack and breakage, therefore repairs personnel and need that building is checked and repaired in time.However, by ancient building material
Material and color etc. require, and material and color etc. to its repair materials also have higher requirement, keep heritage buildings logical as much as possible
Original appearance, no repairing mark can be restored by crossing reparation, and it is high to repair stability；However existing repair materials repairing performance is general,
It is poor for the adherency reinforcing of building therefore still easily cracked and damaged after repair.
Summary of the invention
Based on the above prior art, the purpose of the present invention is to provide a kind of ancient building repair with reinforce composite material and its
Construction method, to solve existing rehabilitating historic building material to the technical problem of the adherency reinforcing difference of ancient building breakage.
In order to achieve the goal above, the technical solution adopted by the present invention are as follows: a kind of ancient building repair reinforcing composite material,
Its raw material composition includes the component of following mass fraction: 20-30 parts of portland cements, 8-12 parts of grass roots ashes, 5-8 parts of bright sand, 2-3
Part active micro mist, 1-2 parts of heavy calcium powders, 3-8 parts of steel fibres, 3-5 parts of resin rubber powders, 3-5 parts of gelatine, 2-4 parts of starch, 2-4 parts
Hydrophober and 10-30 parts of water.
Preferably, ancient building repair group of the raw material composition including following mass fraction for reinforcing composite material
Point: 25 parts of portland cements, 10 parts of grass roots ashes, 6 parts of bright sand, 2.5 parts of active micro mists, 1.5 parts of heavy calcium powders, 5 parts of steel fibres, 4
Part resin rubber powder, 4 parts of gelatine, 3 parts of starch, 3 parts of hydrophober and 20 parts of water.
Preferably, the grass roots ash is mixed to prepare by dry rice straw, sawdust and lime paste according to mass ratio 1:0.5:1.
Preferably, the active micro mist is one of metakaolin, slag powders, zeolite powder.
Preferably, the ancient building repair reinforces the building that the raw material composition of composite material further includes 2-5 mass parts
Pigment.
Preferably, the building pigment is the third ethylene color pigment powder that partial size is 100-200nm.
Preferably, the ancient building repair reinforces the expansion that the raw material composition of composite material further includes 2-5 mass parts
Perlite, expanded perlite can enhance the fastening strength of composite material repairerment.
The present invention also provides the construction methods for reinforcing composite material of the ancient building repair described in one kind, including following step
It is rapid:
Step 1): it is matched according to mass fraction and prepares raw material；
Step 2): by portland cement, grass roots ash, bright sand, active micro mist, heavy calcium powder, steel fibre, starch and hydrophober
It is uniformly mixed, it is spare；
Step 3): gelatine adds water to be heated to boiling, and uniform stirring is at paste；Resin rubber powder is added into paste gelatine again,
Melt resin rubber powder under the waste heat of gelatine, stirring obtains mixing viscose；
Step 4): the material that step 2) mixes being gradually added into mixing viscose, is stirred evenly, and obtains ancient building repair use
Reinforce composite material；
Step 5): ancient building repair is embedded in position to be repaired with reinforcing composite material by cleaning ancient building position to be repaired,
It smashes repeatedly and is rolled to uniformly closely knit, surface floating, polishing completion repairing after air-drying.
There are many function ingredients with addition in composite material is reinforced for the ancient building repair of the application, and combine between each component
Effect, so that the composite material of the application is higher to the adhesiveness of building body, reinforcing is more preferable, more to the property filled up in gap
It is good.Specifically, the application together functions as binder by gelatine and resin rubber powder, and mixes with other function filler
It is even, so that composite material is higher to the adhesiveness of building body, no repairing mark；And gelatine has certain elasticity, Neng Goushi
Variation of building at a temperature of Various Seasonal is answered, therefore building is not likely to produce slight crack.It is additionally added in the application composite material
There is grass roots grey, the addition of grass roots ash enhances the being slightly variable property of repair materials, further such that building is not likely to produce slight crack, simultaneously
Enhance durability, the hydrophobicity, corrosion resistance of repair materials.In addition, be additionally added in repair materials bright sand, active micro mist,
Heavy calcium powder and steel fibre, interaction significantly enhances the intensity of material in all directions between each material, to enhance
To the reinforcement performance of ancient building repair.Also, hydrophober is additionally added in the composite material of the application, one side of addition of hydrophober
Face can prevent from impacting the adhesion property of gelatine in moisture immersion material, on the other hand be capable of the antiacid of reinforcing material
Alkali, ageing-resistant, anti-carbonization, the accumulation of salt in the surface soil, moisture-proof, fungicidal properties, to extend the reparation service life of repair materials.
Compared with prior art, beneficial effects of the present invention are as follows:
Ancient building repair of the invention is higher to the adhesiveness of building body with reinforcing composite material, reinforcing is more preferable, right
The property filled up in gap is more preferable, and repair materials can be slightly variable according to elasticity occurs situations such as variation of ambient temperature and vibration, so that
Slight crack is not likely to produce at building repairerment.In addition, composite material has beneficial antiacid alkali, ageing-resistant, anti-carbonization, the accumulation of salt in the surface soil, prevents
Tide, fungicidal properties, to extend the reparation service life of repair materials.
