Description
Technical field
The present invention relates to the technical fields of concrete construction, refer in particular to a kind of concocting method of mechanism grain fineness number modulus.
Background technique
Current China industry with civilian construction, construction material supply is more and more nervous, and reason is: country and
Forbid the exploitation for carrying out river sand or river sand for the protection of rivers in place.In order to guarantee the needs of construction, people start to broken
Leftover bits and pieces-stone nitre (powder) of rubble carries out regrading and flushing, screens out the gravel particle greater than 5.0mm, forms a kind of machine
Make (artificial) sand.The Machine-made Sand corner angle are clearly demarcated, and rough surface has many advantages, such as that intensity is high, but the fineness modulus of Machine-made Sand is often
It is larger, it is general 3.6 or more, belong to super coarse sand range.Due to the scarcity of natural sand, construction market of the Machine-made Sand in the whole nation
On plastic concrete mixture in be widely used.
The conventional plastic concrete slump is generally in 50mm-70mm, and the slump is answered in 180 ± 20mm pump concrete
The concrete of the phenomenon for just stifled pump often occur in and (vibration) can not being drawn flat with vibrating head, exit accumulates in heaps, cement slurry
Be lost, the fluidity of concrete disappears, when vibration even occur being shaken with vibrating head one eye the phenomenon that.Although Machine-made Sand coagulation
Native intensity can satisfy design requirement, but it will cause the water-retaining property of concrete mix and cohesiveness is poor, in building structure
Gap is more, anti-permeability performance and anti-carbonation properties are low, body structure surface can not receive light and the problems such as coarse and surface voids and pits is more.
In order to overcome the above problem, existing Chinese invention patent (CN107651899A) discloses a kind of dry-mixed mortar machine
The grading method of sand processed and the dry-mixed mortar of preparation: by partial size in the Machine-made Sand portion of 4.75mm or less, fineness modulus 2.3-3.0
Point, it is sieved into three kinds of coarse sand, middle sand, fine sand sand, medium coarse sand fineness modulus 4.3~4.6, middle grain fineness number modulus 3.7~4.0,
