Description
Technical field
The utility model is related to a kind of sand sorting unit for building, more particularly to a kind of sand for building quickly sorts dress
Put.
Background technology
The fineness of sand refers to the average thickness degree that the sand grains of different-grain diameter is mixed.Generally have coarse sand, in
Point of sand, fine sand.The grain composition of sand refers to the blend proportion of sand size particles.As can be seen, if same thick
Thin sand, space is maximum, and the sand collocation of two kinds of particle diameters is got up, and space has reduced, and the sand collocation of three kinds of particle diameters, space is smaller.
As can be seen here, the voidage of sand depends on the collocation degree of sand material particle diameters at different levels.The sand that level is prepared, can not only save water
Mud, also improves the compactness and intensity of concrete and mortar.The thickness of sand is represented with modulus of fineness Mx.Modulus of fineness is bigger,
Represent that sand is thicker.According to modulus of fineness magnitude range, sand is divided into coarse sand, middle sand, fine sand, ultra fine sand.
When configuring concrete, sand in should preferentially selecting.When using coarse sand, sand coarse aggregate ratio should be improved, and keep enough cement
Consumption；When using fine sand, preferably appropriate reduction sand coarse aggregate ratio.Masonry mortar sand should meet the technological property requirement of Sand for Concrete.
Because screed is relatively thin, sand maximum particle diameter should have been limited.For the sand used in ashlar, maximum particle diameter should be less than sand
The a quarter of pulp layer thickness is to 1/5th.For brick setting to be advisable using middle sand, particle diameter cannot be greater than 2.5mm.For
It is smooth to wipe one's face and the mortar of jointing then use fine sand.
