Description
Technical field
The present invention relates to building material technical field, refer to a kind of outdoor rapid-patching motar especially.
Background technology
The ground such as road surface, passageway of the outdoor public square in covil construction community adopts traditional stone material floor tile paving decoration mostly, in construction technology basic adopt half moistening dry-mixed mortar to do laid process (that is: common 32.5 or 42.5 silicate cements add the moistening rear dry mixing of river sand half and become mortar to do the end, then the quiet slurry of cement is watered, stone material floor tile directly spreads the engineering method of pressure again), half moistening dry-mixed mortar is adopted to be the concavo-convex level of original ground structure due to outdoor public square, basic unit's horizontal plane big rise and fall, stone material floor tile is pasted needs thicker screed excessively to glue paving.This engineering method easy construction, floor tile level easily adjusts, but also produces following technological deficiency:
1, common 32.5 or 42.5 silicate cement half moistening dry-mixed mortar water content is low, cement initial stage slaking reaction is slow, very low with stone material bonding strength, need lasting water seasoning, guarantee normal silicate 28d (my god) dental age, so intensity substantially will 28d (my god) after just can reach standard-required.Curing time is very long, time-consumingly requires great effort again.
Although 2 can have time enough to carry out enclosing construction and maintenance in new construction, but due to curing time cycle long tube reason being difficult to ensure, add outdoor ground dehydration very fast, the sand-cement slurry middle and later periods water requirement of maturing process can not be guaranteed, and causes the insufficient intensity of slaking not up to standard.Once being open to traffic, ground stone big area comes off, then when keeping in repair, and because now community has moved in the condition more not possessing comprehensive enclosing construction and maintenance, cause and repair and more fall, mend larger and larger, long-time road surface can not get comprehensive reparation.
Summary of the invention
