How to use a concrete vibrator?

1, concrete vibrator before operation, should check whether the power phase connection is correct, after power-on, such as concrete vibrator without vibration, generally can knock the concrete vibrator end to the ground, after the vibration makes a steady and powerful chirp, before vibrating operation.

2. When the concrete vibrator is working, it should be inserted into the concrete vertically or obliquely, and it can be vibrated after a certain period of time. When vibrating, the concrete vibrator should twitch up and down.

3. In the case of layered casting on components or buildings, when vibrating one layer at a time, the concrete vibrator should be inserted into the vibrated layer to eliminate the interlayer joints and obtain the overall effect.

4. After the concrete vibrator works continuously for half an hour, it should be stopped for a period of time to prevent mechanical heating from damaging parts.

Main classification

According to the classification of cementitious materials:

(1) inorganic cementitious material concrete, such as cement concrete, gypsum concrete, silicate concrete, sodium silicate concrete, etc. ;

② Organic binder concrete, such as asphalt concrete and polymer concrete.

Classification by apparent density:

Concrete can be divided into heavy concrete, ordinary concrete and light concrete according to its apparent density. The difference between these three kinds of concrete is the difference of aggregate.

The apparent density of heavy concrete is more than 2500kg/m&; Sup3, made of particularly dense and heavy aggregate. Such as barite concrete and steel chip concrete. , not affected by x-rays and gamma rays.

Ordinary concrete is often used in buildings, and its apparent density is1950 ~ 2500 kg/m&; Sup3, the aggregate is sandstone.
