Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Currently, the aggregate measuring method in existing mixing plant system is relatively rough to the metering of aggregate, weaken to a certain degree
The quality of concrete.Based on this, a kind of aggregate measuring method, apparatus provided in an embodiment of the present invention and mixing plant batching metering
System can calculate the dosage of aggregate in concrete production material counterweight more accurately, and then promote the quality of concrete.
For convenient for understanding the present embodiment, first to a kind of aggregate measuring method disclosed in the embodiment of the present invention into
Row is discussed in detail.
As shown in Figure 1, being a kind of flow chart of aggregate measuring method provided in an embodiment of the present invention, as seen from Figure 1, the bone
Expect metering method process the following steps are included:
Step S102: aggregate target dosage and water content ratio of aggregate are obtained.
In mixing concrete, due to the difference of aggregate saturation state, the water consumption and aggregate dosage of concrete will affect.
Moisture content of the aggregate in saturated dry surface, the referred to as dry water absorption rate of saturation plane.The match ratio of each material in calculating concrete
When, such as on the basis of the dry aggregate of saturation plane, then it will not influence the water consumption and aggregate dosage of concrete, because of the dry aggregate of saturation plane
It neither absorbs water from concrete, does not also discharge moisture to concrete batching system.Therefore some large hydraulic engineerings, road work
For journey often on the basis of saturated dry surface aggregate, the control of the water consumption and aggregate dosage of such concrete is just relatively accurate.And
In general industry and civil building engineering, mix Design is often on the basis of drying regime aggregate, this is because firm
The dry water absorption rate of its saturation plane of aggregate be usually no more than 2%, and in engineering construction, it is necessary to which often measurement aggregate is aqueous
Rate, to adjust the ratio of component materials of concrete actual amount in time, to guarantee the quality of concrete.
Damp sand has the phenomenon that bulking.Because surface tension caused by moisture pushes particle open, fine sand it is loose
Volume has apparent expansion, this depends on the water content and grade of aggregate.Since most aggregates are under dampness
It is sent on building site, if carrying out ingredient according to volume, use level just has sizable fluctuation.Therefore, based on quality
The mix-design for carrying out concrete batching system has become a kind of standard method.
Therefore, in concrete during mixing and stirring, when actually answering dosage of aggregate is calculated, needs first to obtain the target of aggregate
Dosage and water content ratio of aggregate.
Step S104: calculate that aggregate is practical to answer dosage according to the aggregate target dosage and water content ratio of aggregate；The aggregate is practical
Answer the calculation formula of dosage are as follows: Wreal-g=Waim-g+Waim-g×m+Waim-g×m2, in formula, Wreal-gDosage is answered for aggregate is practical,
Waim-gFor aggregate target dosage, m is water content ratio of aggregate.
Due to the aqueous influence of aggregate, the actual aggregate weight of the aqueous aggregate of constant weight is lower, it is therefore desirable to mend
Foot is because of aggregate weight caused by aqueous.Citing is illustrated below:
500 kilograms of aggregate net weight are needed if once mixing and stirring in Concrete, and the moisture content of the aggregate is 5%, then
According to the practical calculation formula for answering dosage of aggregate:
Wreal-g=500+500 × 5%+500 × (5%)2=526.25 (kilograms)
Can be obtained aggregate it is practical answer dosage be 526.25 kilograms.Compared to existing aggregate dosage calculation method, this implementation
The calculation method that example provides is more accurate to the calculating of aggregate, and the aggregate weight that need to actually match can be some higher, in this way, also to life
The concrete quality of production has further promotion.
A kind of aggregate measuring method provided in an embodiment of the present invention, this method include that acquisition aggregate target dosage and aggregate contain
Water rate；Calculate that aggregate is practical to answer dosage according to the aggregate target dosage and water content ratio of aggregate；The practical calculating for answering dosage of the aggregate
Formula are as follows: Wreal-g=Waim-g+Waim-g×m+Waim-g×m2, in formula, Wreal-gDosage, W are answered for aggregate is practicalaim-gFor aggregate mesh
Standard configuration amount, m are water content ratio of aggregate；The dosage of aggregate in concrete production material counterweight, Jin Erti can be calculated more accurately
Rise the quality of concrete.
A kind of skeletal material metering device is present embodiments provided, as shown in Fig. 2, be the structural schematic diagram of the device, it can by Fig. 2
