Mortar setting time tester
The equipment is used for mensurating masonry and plaster mortar by penetration resistance said the setting time, accord with JGJ70-90 standard requirement.
Technical parameters:
1. The detection range 0 ~ 100 n
2. Try needle sectional area of 30 mm 2
3. Maximum stroke 50 mm
Instrument structure: 1. Handle, 2. Try needle, 3. Post, 4. Base, 5. Pressure display, 6. Try to die, 7. Contact strip, 8. Drill chuck, 9. Support, spindle, 11. Limit nut.
Working principle: its principle by the handle to pressure through the test pin shaft downward slide, try try needle is inserted into the mould mortar in the room, because mortar with time length and condensation hardness change, make trial needle get different penetration resistance, in pressure display reading different kinds of pressure value.
Method of use:
1, stir well mortar load test mould, flowing plane from about 10 mm trowelling, mortar surface exudation not clear
2, will try to die on the disk, at this time will pressure display reset (display Settings see the appendix
3, the operator with the hand will pressure bar vertical downward pressure applied in 10 seconds will try needle slow and evenly vertical penetration mortar 25 ml
4, pressure display shows for the first time measured value, at the same time will limit nut transferred to the proper place, release pressure bar, try needle in the spring force under the action of reset
5 every half hour, according to repeat, when the resistance value of 0.3 MPa to determine when 15 minutes a time, until the resistance value of 0.7 MPa so far
Specific test methods, please refer to People's Republic guohua industry standard JGJ70-90, about building mortar basic performance test method chapter 6, mortar setting time meter concerned regulation is carried out.
