Description
Technical field
The utility model relates to the cubic compressive strength examination criteria part manufacturing technologies such as grinding coagulation great soil group, especially a kind of filler equipment making vibro-hydro pressed concrete cubic compressive strength standard component.
Background technology
Concrete crushing strength refers under the effect of external force, the pressure that unit area can be born, and also refers to the ability that renitency is destroyed.Compressive strength is generally divided into cubic compressive strength and prism (axle center) compressive strength in construction work.
Cubic compressive strength is by " concrete structure engineering construction quality accident specification " (GB50204--2002), the length of side made is 150mm standard cube test specimen, be (20 ± 2) DEG C in temperature, relative humidity is the wet environment of more than 95% or the Ca (OH) that do not flow
2under the condition of maintenance in full conjunction solution, through 28d maintenance, the intensity of the concrete ultimate compressive adopting standard test method to record, uses
f cu represent.
Prism (axle center) compressive strength is in reinforced concrete structure calculates, and according to structure actual conditions, calculates axis compression member often using prismatic compressive strength as foundation, because it is close to the actual forced status of concrete component.The standard test method of prism (axle center) compressive strength is the standard specimen making 150mm × 150mm × 300mm, under the condition of standard curing, records its compression strength value, is prism (axle center) compressive strength, uses
frepresent.
By " concrete for hydraulic structure testing regulations " (SL 352-2006), the instrument and equipment that present stage making roller compacted concrete cubic compressive strength standard specimen adopts is:
1. the shaking table (device with fixing die trial) of jolt ramming facility: vibration frequency 50Hz ± 3Hz, amplitude 0.5mm ± 0.1mm or vibration moulding device, quality 35kg ± 5kg, frequency 50Hz ± 3Hz, amplitude 3mm ± 0.2mm.With dismountable die trial pressing plate (pressing plate should have certain rigidity, its length of side or diameter 5mm about less of die trial size).
2. die trial: specification is determined depending on maximum aggregate size.
3. shaping cover die: the Internal periphery size of cover die is identical with die trial, height 50mm, not yielding and can be fixed in die trial.
4. shaping saddle weight and bearing plate: shape is consistent with surface of test piece shape, is dimensioned slightly smaller than surface of test piece size, according to different die trial size, is 4.9kPa by Mass adjust-ment to the roller compacted concrete specimens surface pressure of saddle weight and bearing plate.
Specimen molding process is as follows:
1. die trial is cleaned, assembled good, be coated with skim mineral oil in mould.
If 2. building stones exceed regulation in roller compacted concrete mixture, then screened out Large stone building stones by wet screening.
3. roller compacted concrete mixture is mixed point two-layer loading die trial evenly.Plug and pound the die trial of number of times to length of side 150mm, 300mm and be respectively 25 times and 40 times.When plugging and pounding from die trial periphery, spirality is carried out.When plugging and pounding upper strata, tamper should insert lower floor 1-2cm, every layer plug and pound after with flat cutter along mould all over inserting one time.By mixture surface evening in mould.
4., time shaping with shaking table, die trial should be fixed on shaking table, adds cover die, puts bearing plate and saddle weight, by artificial righting saddle weight or lead with guide pole.Time shaping with vibration moulding device, by vertical for the Vib. that pressing plate (shape is identical with surface of test piece shape) the is housed mixture surface be placed in die trial, with just hand steered, artificially do not pressurize or mention.
5. when height of specimen is 150mm, one time pressurization and vibration is shaping, and time of vibration is 2-3 times of VC value.When height of specimen is 300mm, extrusion forming at twice.Time of vibration, bottom is 2 times of mixture VC value, and upper strata is 2-3 times of mixture VC value, is as the criterion with surperficial bleeding.
6. wipe one's face after specimen molding at once, require along die orifice floating.
When using the said equipment and method to make cubic compressive strength standard specimen, carry out in the process of vibration-extrusion at use shaking table, need artificial righting saddle weight, otherwise saddle weight is easily because vibration is subjected to displacement, not only consolidation effect may be affected, because saddle weight quality is comparatively large, also easily cause danger if drop.In addition, because the personnel of righting saddle weight cannot simultaneously operating vibration platform, vibration-extrusion work at least needs two people to complete, and reduces the work efficiency that test specimen makes to a certain extent.
