混凝土含气量测定仪的操作规程:

 ★用湿布擦净量钵与钵盖内表面,并使量钵呈水平放置。

★将新拌混凝土拌合物均匀地装入量钵内,使混凝土拌合物调出量钵少许。装料时可用捣棒稍加插捣,装好后,当用振实台(振动参频率50Hz,空载时振幅0.5±0.1mm)振实时,在振动过程中如混凝土拌合物沉落到低于内口,则应随时添加混凝土拌合物,振动至混凝土表面平整,呈现釉光时即停止振动。

不用振动台而换用捣棒捣实时,将混凝土拌合物分三层装入,每层捣时后约为量钵高度的三分之一,插捣底层时捣棒应贯穿整个深度。插捣上层时捣棒应插入下层10~20 mm。每层捣实后,可把捣棒垫在量钵底部,将量钵左右交替地颠击地面15次。

★ 捣实完毕后,应立即用刮尺刮去表面多余的混凝土拌合物,表面如有凹陷应予填补,然后用镘刀抹平,并使其表面光滑无气泡。

★ 擦净量钵和钵盖边缘,将“O”形橡胶密封圈(238×8.6)放于钵盖边缘的凹槽内,盖上钵盖,用夹子夹紧,使之气密良好,并用水平仪检查水平。

★ 打开小龙头和出气阀,用注水器从小龙头处往量钵中注水直至水从气阀出口流出,再关紧小龙头和出气阀。

★关闭好所有的阀门后,用打气筒打气加压,使表压稍大于0.1MPa。

注:⑴每当读取压力时,用指尖轻弹表盘并待指针停止摆动后再读数。

 ⑵ 0.1MPa压力线为仪器的初始压力线,0.1MPa为仪器的初始压力。

★按下阀门2~3次,用木锤轻敲量钵的四周,使压力均匀分布于试样各处,再次按下阀门杆,待压力表指针稳定后,测得压力表读数,并根据仪器标定的含气量与压力读数关系曲线,得到所测混凝土拌合物样品的仪器测定的表观含气量值A1

Operation rules of concrete gas content measuring instrument:

 ★ Wipe the inner surface of the measuring bowl and the lid with a damp cloth, and place the measuring bowl horizontally.

★ Fill the fresh concrete mixture evenly into the measuring bowl and make the concrete mixture out of the measuring bowl a little. When loading, you can use a tamper to insert and tamp slightly. After installation, when using a vibrating table (vibration parameter frequency 50Hz, no-load amplitude 0.5 ± 0.1mm) to vibrate in real time, during the vibration process, the concrete mixture sinks to Below the inner mouth, concrete mixture should be added at any time, and vibration should be leveled on the concrete surface, and stop vibrating when glaze appears.

Instead of shaking the table with a tamping rod, load the concrete mixture in three layers. After each layer is punched, it is about one-third of the height of the measuring bowl. When the bottom layer is inserted, the tamping rod should penetrate the entire depth. When inserting the upper layer, the plunger should be inserted into the lower layer 10 to 20 mm. After each layer is tamped, you can pad the tampon at the bottom of the measuring bowl and hit the ground alternately from left to right 15 times.

★ After tamping is completed, the excess concrete mixture on the surface should be scraped off with a scraper. The surface should be filled with any dents, and then smoothed with a trowel to make the surface smooth and free of air bubbles.

★ Wipe the edges of the measuring bowl and bowl cover, place the "O" shaped rubber seal ring (238 x 8.6) in the groove on the edge of the bowl cover, cover the bowl cover, clamp with a clip to make it airtight, and use The spirit level checks the level.

★ Open the small faucet and the air outlet valve, use a water injector to inject water from the small faucet into the measuring bowl until the water flows out of the air valve outlet, and then close the small faucet and the air outlet valve.

★ After closing all the valves, pressurize with a pump to make the gauge pressure slightly higher than 0.1MPa.

Note: ⑴Every time you read the pressure, flick the dial with your fingertips and wait for the hands to stop swinging before reading.

 ⑵ 0.1MPa pressure line is the initial pressure line of the instrument, and 0.1MPa is the initial pressure of the instrument.

★ Press the valve 2 or 3 times, and tap the circumference of the measuring bowl with a wooden hammer to distribute the pressure evenly throughout the sample. Press the valve rod again. After the pointer of the pressure gauge stabilizes, measure the pressure gauge reading and follow The relationship curve between the gas content and pressure readings calibrated by the instrument to obtain the apparent gas content value A1 determined by the instrument of the concrete mixture sample measured


混凝土含气量测定仪测试完毕后:

★打开出气阀,从量钵中放气。如需对同一试样重量测定含气量时,则重复上述5-7步骤。

★打开小龙头,松开夹子,取下钵盖。

★ 倒掉量钵中的混凝土拌合物试样,清洗钵盖和量钵的内表面。

★含气量测定仪如不连续使用,需打开微调阀放气,使气室压力与大气压一致。

注:在操作过程中,如气室气压通过微调阀放尽,而量钵内还有压力时,不能按下阀门杆,否则会把水吸入气室,使以后的测试产生误差。

After testing the concrete gas content tester:

★ Open the air outlet valve and deflate from the measuring bowl. If you need to determine the gas content of the same sample weight, repeat the above steps 5-7.

★ Open the small faucet, loosen the clip, and remove the lid.

★ Discard the concrete mixture sample in the measuring bowl, and clean the lid and the inner surface of the measuring bowl.

★ If the gas content measuring instrument is not used continuously, open the fine adjustment valve to deflate, so that the pressure of the air chamber is consistent with the atmospheric pressure.

Note: During the operation, if the air chamber pressure is exhausted through the fine adjustment valve, and the pressure is still in the measuring bowl, the valve rod cannot be pressed, otherwise water will be sucked into the air chamber, which will cause errors in subsequent tests.
