Background technology
The pattern of fine aggregate is the key affecting concrete work performance, mechanical property and endurance quality thereof, and especially for the concrete with greatly mobile, fine aggregate size-grade distribution and pattern determine concrete mobility.By traditional impact of extensive idea and the restriction of detection means, as large ground material---the quality control of fine aggregate constrains the progress of concrete technology always.The standard regulation current for fine aggregate Task-size Controlling has modulus of fineness and grating, and modulus of fineness evaluates the fineness of aggregate, and grading curve evaluates the size-grade distribution of aggregate.What Chinese scholars research was more is utilize the method for image procossing to evaluate the pattern of fine aggregate, this Measures compare is directly perceived, but need high image picking-up apparatus and image processing software, it is applied and is restricted, and be not suitable for the field control of fine aggregate, even these cause the detection method of fine aggregate feature image process not bring standard into.Evaluate for the voidage that adopts in the pattern correlation parameter standard of fine aggregate, the normal value of voidage is at 44-47% more.Specify that the voidage of fine aggregate should not be greater than 44% at " construction sand " GB14684-2011, the voidage of " Cement Concrete in Highway Engineering Machine-made Sand " regulation fine aggregate should be less than 45%, and the voidage of " Machine-made Sand is application technology guide in concrete " regulation fine aggregate should be less than 47%.The standard of " highway engineering gather materials testing regulations " JTG E42 foreign, adopts clearance rate method and flowing time method to carry out Indirect evaluation fine aggregate structural parameters.The assay method (201210269203.1) of " detection method of the very irregular particle shape of a kind of concrete coarse aggregate " (ZL 20121026937.0), a kind of concrete coarse aggregate irregular particle shape content, the detection method (201210111903.8) of the very irregular particle shape of concrete coarse aggregate are according to the definition of coarse aggregate faller gill shape, propose the method for testing of the irregular and very irregular particle shape content of coarse aggregate, by detect the test of the inapplicable fine aggregate of granule number quantitative limitation the method." fine aggregate angularity proving installation " (ZL 201320890723.4) adopts 5 gather materials hole and 5 splicing cylinders to overcome the problem needing repeatedly parallel experiment." Coarse aggregates angularity analyzer and using method " (201310025049.8) are used for reference fine aggregate and are flowed through the principle of fixed valve time to test the corner angle of coarse aggregate.The test philosophy of fine aggregate structural parameters bulk density method, clearance rate method and flowing time method involved in current standard is basically identical, all allow the valve of fine aggregate particle diameter certain size, flow in a splicing container, test the voidage after fine aggregate delivery time and filling containers, but different in proving installation size, profile etc.These methods mutually isolated, not there is comparability, and have that measuring accuracy is low, human factor impact is large and need the shortcomings such as repeatedly parallel experiment.
Summary of the invention
The utility model is for mutually isolating between current fine aggregate structural parameters method of testing, not having comparability, and have that measuring accuracy is low, human factor impact is large and needs the shortcomings such as repeatedly parallel experiment, invent a kind of have automatically record delivery time, automatic weighing quality and bulk density calculated, voidage and the proving installation of delivery time automatically, to realize, to the accurately test fast of fine aggregate pattern three parameters, proposing the utility model.
The technical solution of the utility model: a kind of fine aggregate structural parameters device for quick testing, it is characterized in that: this device is made up of fixed volume funnel 1, many storehouses splicing container 2, support 3, gearing 4, measuring apparatus 5, time set 6, quality and time wireless transport module 7, valve 8 and system process software, the valve corresponding with container storehouse number divided into by funnel 1, the opening and closing of valve 8 is controlled by gearing 4, funnel 1 is placed on support 3, and splicing container 2 is placed in measuring apparatus 5.Quality and time wireless transport module 7 are by container mass and be full of the container mass after fine aggregate, funnel lower end valve open to splicing container is full of fine aggregate and fixed volume funnel 1 fine aggregate all flows out time tranfer is to system software, on the parameter basis such as input fine aggregate density, the built-in formula of system process software is utilized to carry out the parameters such as bulk density calculated, voidage, delivery time.
The valve corresponding with container storehouse number divided into by the funnel 1 of described fine aggregate structural parameters device for quick testing, and tapering 40-70 ° of funnel adjustable, and valve number 3-6 variable, and the opening and closing of valve 8 is controlled by gearing 4, and funnel 1 is placed on support 3.
Many storehouses splicing container 2 of described fine aggregate structural parameters device for quick testing is placed in measuring apparatus 4, the storehouse number of many storehouses splicing container is corresponding with valve number, for 3-6 variable, measuring apparatus weighing result passes to system process software by wireless transport module.
