Description
Technical field
The present invention relates to building material technical field, a kind of outdoor rapid-patching motar is particularly related to.
Background technology
The ground such as road surface, passageway of public square is filled using traditional stone material floor tile paving mostly outside civil buildings cell room
It is basic in decorations, construction technology to use semi-moist dry-mixed mortar dry-laid method (i.e.：Common 32.5 or 42.5 portland cements add river sand
Dry mixing does bottom into mortar after semi-moist, then waters the quiet slurry of cement, and stone material floor tile directly spreads the engineering method of pressure again), using semi-moist
Dry-mixed mortar is due to the concavo-convex level of original ground structure of outdoor public square, and basic unit's horizontal plane big rise and fall, stone material floor tile glues
Patch needs thicker screed excessively to glue paving.This engineering method easy construction, floor tile level is easily adjusted, but also produces following technology
Defect：
1st, common 32.5 or 42.5 portland cement semi-moist dry-mixed mortar water content are low, and cement slaking reaction at initial stage delays
Slowly, with stone material adhesive strength it is very low, it is necessary to continue water seasoning, just can guarantee that normal silicate 28d (my god) dental age, so by force
Degree substantially will 28d (my god) after can be only achieved standard requirement.Curing time is very long, time-consuming and laborious.
Although the 2, can there is time enough to carry out enclosing construction and maintenance in new construction, due to the curing time cycle
It is difficult to ensure that in long management, along with outdoor ground dehydration is very fast, the water requirement of cement mortar middle and later periods maturing process cannot
Ensure, cause to cure insufficient intensity not up to standard.Once being open to traffic, ground stone large area comes off, then when repairing, due to now small
Area has moved in condition with less comprehensive enclosing construction and maintenance, causes to repair and more falls, mends bigger and bigger, and long-time road surface is obtained
Less than comprehensive reparation.
The content of the invention
To overcome above-mentioned technological deficiency, it is an object of the invention to propose it is a kind of time-consuming it is shorter, without water seasoning, can
Stone material floor tile, intensity outdoor rapid-patching motar up to standard outside Rapid-Repair room.
The technical scheme used for：
A kind of outdoor rapid-patching motar, by weight it include following component and content：
