The aggregate storage coefficient test device of the utility model is used for the storage coefficient of test architecture garbage regeneration aggregate
Test philosophy are as follows: the storage coefficient of construction refuse regenerated aggregate refers under aggregate saturated dry surface, the building of unit mass
After garbage regeneration aggregate water storage saturation, the ratio of the quality of the quality and recycled aggregate of water.The natural saturation plane that sieve has taken is done
The recycled aggregate of state (its internal void of aggregate is aqueous reach saturation and its dry tack free) is sprayed water using watering can, until full
With it is rear, test water spray quality and the percentage of recycled aggregate quality are storage coefficient.
By the measurement to construction refuse regenerated aggregate storage coefficient, the water storage performance of building waste can be specified, for sea
Continuous city selects construction refuse regenerated aggregate to provide reference, while can make full use of to construction refuse regenerated aggregate, this reality
It can also be used for the measurement of conventional aggregate storage coefficient with novel aggregate storage coefficient test device, and aggregate can be measured simultaneously
Storage coefficient and water absorption rate.
Although having made to retouch in detail to the utility model with a general description of the specific embodiments in this specification
State, but on the basis of the utility model, it can be made some modifications or improvements, this be to those skilled in the art it is aobvious and
It is clear to.Therefore, it is practical new to belong to this for these modifications or improvements on the basis of without departing from the spirit of the present invention
The claimed range of type.
