Therefore, up to the present, can utilize system 1 of the present invention and method to try to achieve to comprise the SSD proportioning of SSD sand amount, cement amount, flying dust amount, hearthstone amount, SSD coarse aggregate amount, SSD clear water amount and pharmaceutical quantities.
Then, shown in step 26, just can according to following because of the moisture water yield of material adjust equation (9～(11), utilize actual proportioning computing module 13 to calculate and comprise cement amount, hearthstone amount, flying dust amount, actual sand amount, actual coarse aggregate amount, and the actual proportioning of actual clear water amount.
Actual coarse aggregate amount=SSD coarse aggregate amount * (1+ (coarse aggregate weight in wet base-coarse aggregate dry weight)/(coarse aggregate dry weight-coarse aggregate water absorption rate)) (9)
Actual sand amount=SSD sand amount * (1+ (sand weight in wet base-sand dry weight)/(sand dry weight-sand water absorption rate)) (10)
Actual clear water amount=SSD clear water amount-(actual coarse aggregate amount+actual sand amount-SSD coarse aggregate-SSD sand amount) (11)
Then, shown in step 27, utilize this recycle-water computing module 13, according to this recycle-water parameter group 118, can calculate and consider the final shipment proportioning 15 that concrete premixing factory has waste water reclamation apparatus, details are as follows.
When concrete premixing factory utilizes waste water reclamation apparatus to use concrete recovery waste water, note the variation of " concentration " when taking, more need control solid (S.S.) wherein to add behind the concrete influence to compression strength, so utilizing the spendable recycle-water consumption of recycle-water computing module 13 computings of native system 1, before final clear water amount and the final sand amount, need to determine this recycle-water parameter group 118 by test earlier, wherein this recycle-water parameter group 118 comprises recycle-water solid concentration (%), recycle-water solid water absorption rate (%) and total clay content control point.
So-called recycle-water solid concentration is meant, the solid weight percentage in the recycle-water except liquid, and its formula is:
Recycle-water solid concentration (%)=(the solid weight/recycle-water sample in the recycle-water sample is heavy) * 100% (12)
And the formula of recycle-water solid water absorption rate (%) is:
Recycle-water solid water absorption rate (%)=(the solid sample of the solid sample weight-dry shape of SSD shape is heavy)/(the solid sample of dry shape is heavy) * 100% (13)
In addition, can test determining total clay content control point equally, its clay content for allowing in the concrete proportioning is 6.1% if draw total clay content control point with test for example, then be illustrated in and use under the specific raw materials situation, the clay content that is allowed is " in the proportioning 6.1% of dry sand amount ".Yet the material of varying environment is not quite similar, so the result of testing also is not quite similar, and the data of this total clay content control point must obtain via test, in the hope of the data of " localization ".
In addition, because the concrete proportioning that is produced by Fig. 2 step 25 is the SSD proportioning, its aggregate (containing coarse aggregate and sand) weight is all done (SSD) state with saturation plane and is presented, and the normal coarse aggregate that uses and sand more or less also can some clay contents, so the clay content that should convert the coarse aggregate and the sand of proportioning to drying regime, and add that total clay content behind the solid content that uses recycle-water must not surpass the total clay content control point with the dry sand amount of this proportioning.Therefore, can set up " allowing to use the maximum amount of recycle-water " of this proportioning by following equation (14), i.e. recycle-water consumption control amount.
Dry sand amount in the solid amount=proportioning of recycle-water * total clay content control point (14) in the solid amount+proportioning of dry sand in the solid amount+proportioning of dry raw aggregate in the proportioning
Then,, can find out the highest solid amount of recycle-water in this proportioning, so can try to achieve recycle-water consumption control amount by untiing aforesaid equation (14).
In other words, if after adding recycle-water in the proportioning, wherein use the control of clear water and recycle-water consumption to have very big-difference, because recycle-water is made up of clear water and other solids.That is to say that if when using recycle-water, the clear water content in this recycle-water will be by the some as the proportioning flat water, solid wherein then should be the some of sand.Therefore, revise back clear water amount and recycle-water consumption in the final shipment proportioning 15, two parameters such as original actual clear water amount that are subjected to recycle-water consumption control amount and original actual proportioning (not considering recycle-water) are controlled.
This recycle-water control amount is the aggregate clay content used according to proportioning and recycle-water solid content and decide.This parameter is a real number.When its operation result (equation (14)) was zero or negative value, the expression proportioning can't add recycle-water again; Have only when recycle-water control amount on the occasion of the time, proportioning just can add recycle-water.Below comprise that when revising back clear water amount, recycle-water consumption and revising the final shipment proportioning 15 of back sand amount, two logics of required use are judged a formula and an equation (15) calculating according to recycle-water parameter group 118 for the recycle-water computing module 14 among the present invention.
The logic that is used for computing modification back clear water amount judges that formula is as follows:
IF recycle-water consumption control amount≤0
THEN revises actual clear water amount in back clear water amount=former actual proportioning
ELSE
IF (actual clear water amount-recycle-water control amount in the former actual proportioning)≤0
THEN revises back clear water amount=0
ELSE revises the clear water amount in actual clear water amount-recycle-water control amount in back clear water amount=former actual proportioning
The logic that is used for computing recycle-water consumption judges that formula is as follows:
IF recycle-water consumption control amount≤0
THEN recycle-water consumption=0
ELSE
IF (actual clear water amount-recycle-water control amount in the former actual proportioning)≤0
THEN recycle-water consumption=the have recycle-water consumption of the clear water amount identical with actual clear water amount in the former actual proportioning
ELSE recycle-water consumption=recycle-water consumption control amount
Aspect the solid (sand) in handling recycle-water,, be decided by the solid concentration and the recycle-water consumption control amount of recycle-water by whether adding recycle-water in the aforementioned concrete proportioning as can be known.If result of calculation shows in the time of can adding recycle-water in the proportioning, the unit volume of proportioning is bound to increase because of the solid in the recycle-water adds, so must be with the solid in the recycle-water when some, with the sand amount in following equation (15) the correction proportioning as sand.
Revise back sand amount=do not add former actual sand amount-recycle-water consumption * recycle-water solid concentration * (1+ sand water absorption rate) (15) of recycle-water
