Description
Technical field
The invention belongs to building material field, it is related to a kind of admixture particle diameter less than the dry powder and mortar of 5mm waste stone dusts.
Background technology
A large amount of waste stone dusts can be produced in processing of stone production process, they had not only taken up room but also had polluted environment, right at present
Its utilization ways are few, can only simply fill accumulation treatment, and how to process these waste stone dusts has turned into asking for urgent need solution at present
Topic.
Dry powder and mortar is also referred to as dry-mixed mortar or dry mortar powder, is that with the addition of different admixtures what Endogenous were produced
The mortar product of the stable performance mixed with various additives and with aggregate and Binder Materials, can unify pack and be dispensed into build
Build the product that engineering location is directly used by builder scene.General, the composition of dry powder and mortar mainly includes gelling material
Material, aggregate and various additives etc..Waste stone dust is applied in dry powder and mortar, it is possible to resolve existing waste stone dust pollutes asking for environment
Topic, and certain economic worth can be created.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of dry powder and mortar of admixture waste stone dust, this is done
Powder mortar with the addition of waste stone dust of the particle diameter less than 5mm, be that the high value added utilization of waste stone dust is provided a method that.
The technical solution adopted by the present invention is：
It is a kind of to fill dry powder and mortar of the particle diameter less than 5mm waste stone dusts, prepared by the raw material including following parts by weight：
30~40 parts of cement,
10~30 parts of waste stone dust,
30~50 parts of sand,
0.5~3 part of re-dispersible glue powder,
0.5~1 part of polyvinyl alcohol,
1~1.5 part of polycarboxylate water-reducer,
0.1~0.2 part of polypropylene fibre.
Preferably, the cement is 42.5 Portland cements.
Preferably, the waste stone dust is waste marble powder, one or two mixture of useless granite stone powder.
Preferably, the particle diameter of the waste stone dust is less than 5mm.
Preferably, the sand includes the sand of various different-grain diameters distribution.
Preferably, the polypropylene fibre is the chopped strand of 5~20mm of length.
Preferably, the dry powder and mortar can be used as masonry mortar.
The present invention is had the advantage that：
The invention provides a kind of dry powder and mortar for filling waste stone dust, the waste stone dust by particle diameter less than 5mm is added into dry powder and mortar
In, it is possible to reduce the consumption of cement, reduces cost, dry powder and mortar can be used as masonry mortar, be the high added value profit of waste stone dust
With there is provided a kind of new method.
