The mixing of a special solution from these components is shown.
Close-up - test tubes on stands, a hand takes one of the test tubes, drips from it onto laboratory glass.
A female employee examines a mixture on a laboratory slide under a microscope.
Close-up - an image of the mixture magnified many times under a microscope (it is clear that the cement particles are connected to each other and that there is water inside).
The frame shows laboratory glassware with different fillings - cement, sand, crushed stone, water, a flask with dark liquid C-3 (superplasticizer) appears.
The woman pours superplasticizer into a container where concrete is mixed.
The process of mixing concrete mixture.
Animated insert - an image of the mixture (it is clear that the cement particles are simultaneously charged and repel each other, water is released).
The process of mixing concrete mixture.
The superplasticizer lubricates the rough surface of the cement particles, forming a thin film around them.
Close-up - an employee lifts a cone-shaped form, underneath which there is hardened cement.
Rulers in concrete, which is shaped like a cone.
Close-up - hands lift a cone-shaped form, the concrete underneath does not hold, but spreads in different directions.

Large - grade 500 concrete under a press.
Large - the arrow on the device is moving.
The concrete begins to crumble and break under the pressure.
Large - the arrow on the device is moving.
The concrete cube crumbles under the pressure of the press, pieces break off, etc.
The arrow on the device goes off the scale.
The concrete cube is further destroyed.
Large - a hand takes a concrete cube with the inscription C-3 (with superplasticizer).
The cube is placed under the press.
Large - the arrow on the device is moving.
The cube is almost not destroyed under the pressure.
Only when the arrow on the device begins to go off the scale does the cube begin to crumble.
Large - dark liquid in a flask.
Panorama of a large map of the types of soil salinization chemistry in the USSR. Shown are samples of concrete that stood for a year in a five-percent sodium sulfate solution. (The salt corroded ordinary concrete, while the sample with the addition of a superplasticizer was almost not deformed).
