Description
Technical field
The invention belongs to field of constructional engineering material, and in particular to a kind of high-performance polymer mending mortar.
Background technology
In the laying of traffic highway bridge floor and building, usually used concrete progress operation, but concrete
Setting time is slow, and maintenance cost is high, and the area corroded in severe cold, more often there are it is easy to crack, difficult be laid with, it is not strong with reference to power
It is not durable, the problems such as flow is cumbersome, how the adaptation severe cold environment of simple and efficient high quality constructs and ensures that laying quality is this
Problems to be solved by the invention.
The content of the invention
For overcome the deficiencies in the prior art and realize above demand, the present invention provides a kind of suitable ice box concrete
Component is laid with and repairing, high-performance polymer mending mortar not easy to crack.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of high-performance polymer mending mortar, the height
Performance polymer mending mortar is made of the raw material of following percentage by weight：
Double quick anticracking sulphur aluminium cement 34~36%, cement 4~6%, gathers element acid 0.14~0.16%, watt can rubber powder 2.4~2.6%, it is fine
The plain mud 0.09~0.11% of dimension, lithium carbonate coagulant 0.24~0.26%, silicon magnesium lubricant 0.29~0.31%, sodium citrate 0.06
~0.08%, washed-out sand 39~41%, surplus is quartz sand.
Preferably, the cement is selected from one kind of portland cement or Portland cement, cement grade 42.5
Or 52.5.
Preferably, the washed-out sand, which need to sieve, need to dry use, the sieving is 50~100 mesh.
Preferably, the quartz sand, which need to sieve, need to dry use, the sieving is 20~50 mesh.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of use of high-performance polymer mending mortar
Method：Water is first added in whisking machines and is stirred while adding mending mortar continues stirring 3~5 minutes, but must not be less than 3
Minute, building substrate surface is cleared up, clean free from admixture is kept and moistens building substrate surface with water saturates, repaiied what is be stirred
Stop-off is starched uniform trowel and is smeared in building substrate surface.
Preferably, water：The weight proportion (1~2) of mending mortar：10.
Preferably, the reference dosage of mending mortar is 100mm 18~23kg/ of thickness ㎡.
Preferably, mending mortar construction preference temperature is 5~45 DEG C, the construction time is 1~2h.
Mending mortar prepared by the present invention is easy to operate, and when construction need to only add water to stir, and is applied with good
Work workability, and the combination power of concrete component are strong, do not hang when trowel is smeared, and can be widely applied to the plane of concrete component, stand
Face and top surface, and do not crack after hardening, do not shrink, intensity is high, has good freeze-thaw resistance, salt-freezing resistance, anti-fluorine ion
Permeability, durable.
