Abstract
The invention discloses a kind of bonding for paster leatheroid brick and the fast rigid mortar of joint filling, the mortar includes the composition of following parts by weight：Aluminate cement 300 480；Portland cement 50 150；Sand 400 550；Kaolin 30.0 70.0；Rubber powder 18.0 28.0；Cellulose ether 2.0 3.5；Water reducer 1.0 2.0；Hydrophober 3.0 6.0；Retarder 0.4 1.0.The fast rigid mortar of the present invention has efficiency of construction high, and cohesive force is strong, and brickwork joint is closely knit full, the advantages of high-early-strength, and it is the decorating surface brick engineering using paster leatheroid brick to be particularly suitable for use in facing.
Description
Technical field
The present invention relates to the bonding for paster leatheroid brick and the fast rigid mortar of joint filling.
Background technology
Traditional paster leatheroid brick work progress is first to be layered on the viscous of leatheroid brick with the Wall or floor tile adhesive mortar being stirred
Veneer, is then affixed to metope, pats with strength, it is pasted jail with base course wall, and mortar is poured into seam.Then with water by paper
Face is fully soaked, and observes the joint filling situation of brickwork joint, by brickwork joint insatiable hunger capable compacting of squeegeeing again everywhere.In order to avoid above-mentioned conventional method
Security-hidden trouble is brought to entirely surface-veneer engineered, it is necessary to solve following 4 problems：
1st, during decorating surface brick engineering, stickup dedicated mortar and each have their own execution standard of joint filling dedicated mortar and the tool of face brick
Body index request, it is impossible to mutually replace, above-mentioned situation is exactly that adhesive instead of gap filler.
2nd, leatheroid is soaked, could thoroughly torn before paper-tear picture by paster leatheroid brick with substantial amounts of water, is exposed whole
Individual finishing effect.Joint filling mortar is a kind of mortar of cement base, after initial stage is washed with water, it is easy to the situation of the accumulation of salt in the surface soil occur.
3rd, while workmen's bath wetting, mortar now does not reach certain intensity, is unable to undergo water punching, only
The damage brought at the joint filling of paper in varying degrees can have been torn to side, and mortar has been flushed on brick face, has been eventually caused
Mortar is flushed away at one seam, stitches not full, is to be rushed out the slurry come on brick, can be seen the materials such as cement mortar, sand, make
Effect into whole finish coat is had a greatly reduced quality.
Although the 4, after paper-tear picture, having carried out measure of squeegeeing, still there is the substantial amounts of place of squeegeeing not tamp, particularly in the winter
My god, rainwater is permeated inwards by the not place of tamping, and meeting freezing and expansion after low temperature, whole finish coat will produce showing for the brick that comes off
As.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides the fast hard of a kind of bonding for paster leatheroid brick and joint filling
Property mortar.
The bonding and the fast rigid mortar of joint filling for paster leatheroid brick that the present invention is provided, including following parts by weight
Composition：
Under two kinds of cementitious composite systems, it can both make mortar strength stable, ordinary silicon can be substantially effectively absorbed again
The Free Ca that hydrochlorate aquation is produced2+, alkali burnout resistance can reach JC/T1024-2007 standards.It it is possible to additionally incorporate sand, rubber powder, fiber
Plain ether, kaolin, water reducer and hydrophober, play thickening function, assign mortar plasticity, can significantly improve mortar in brickwork joint
The filling effect at place, makes product have efficiency of construction high, and cohesive force is strong, and brickwork joint is closely knit full, the advantages of high-early-strength.Mortar belongs to
In fast gravity die mortar, only add after retarder, can just ensure the engineering time of mortar.
Preferably, the aluminate cement is aluminate cement CA60.Aluminate cement CA60, hydration rate is fast, early stage
Intensity is high, and hydrated product not but not produces Ca2+, and the Ca of 42.5R Portland cements generation can be consumed2+, drop
Low accumulation of salt in the surface soil risk.
Preferably, the Portland cement is 42.5R Portland cements.42.5R Portland cement is not
Only quick-hardening the characteristics of, with the use of aluminate cement CA60, the stability of mortar strength can also be improved.
Preferably, the sand is the river sand of the mesh of particle diameter 70~120.Using the river sand of this particle size range, mortar can be made
Construction workability reach that most preferably wherein the river sand of fine grain can be sufficient filling with the skeleton space that coarse grain footpath river sand is constituted.
Preferably, the kaolin is calcined kaolin, and kaolin is the clay using kaolinite as main component, is a kind of
Inorganic salts, its main chemical compositions are Al2O3、SiO2, have soapy feeling, be readily dispersed in water.Hydrated cementitious production can also be consumed
Raw Free Ca2+。
Preferably, the hydrophober is zinc stearate or calcium stearate.Stearate is a kind of inherently water insoluble
Salt material, is added in mortar, without being fully cured when mortar, it is possible to significantly improve the hydrophobicity of mortar.
Hydrophober is to reduce the water absorption rate of mortar, improves the hydrophobicity at mortar initial stage.Water reducer can significantly reduce mortar
Mixing water, reduces porosity, makes mortar more closely knit, improves mortar strength.Both there is respective function, be required composition.
Preferably, the retarder is citric acid.Citric acid acts not only as cement retarder, it is ensured that mortar is applied
Work, can also improve the early strength of cement, and not influence the later strength of cement.
Preferably, above-mentioned bonding and the fast rigid mortar of joint filling for paster leatheroid brick, the weight fraction of each composition is：
Having the beneficial effect that relative to prior art of the invention：
(1) by adding kaolin, under two kinds of cementitious composite systems, normal silicate water can substantially effectively be absorbed
Change the Free Ca produced2+, and can also thickening function, assign mortar plasticity, mortar filling out at brickwork joint can be significantly improved
Fill effect.
(2) fast rigid mortar will also ensure enough apply except to there is the function that can have quick-hardening after the stirring that adds water
Between man-hour.According to the mortar obtained by instant component, the time before wall on paster leatheroid brick can either be ensured, also with paper
Skin brick fix after, mortar no longer obtain external force effect under, mortar can quick-hardening, after 2 hours compression strength up to 3MPa with
On, the damage phenomenon brought at the joint filling of paper in varying degrees has been torn to side when bath can be avoided to soak, can have been kept away
Exempt from the slurry in seam being flushed to brick face, pollute the phenomenons such as metope.
(3) present invention has efficiency of construction high, and cohesive force is strong, and brickwork joint is closely knit full, the advantages of high-early-strength, particularly suitable
It is the decorating surface brick engineering for using paster leatheroid brick in facing.
