An apparatus and method for producing fluid concrete include a first mixer configured to mix at least water and cement so as to make a low fluidity concrete having consistency class ≤S2, a truck mixer that can be configured to mix the low fluidity concrete with further water so as to make a fluid concrete having consistency class ≥S2, and a water supply and at least a cement supply configured so that the apparatus or method can produce fluid concrete. The apparatus and method include a control and adjustment unit, connected to the water supply and at least to the cement supply, configured to selectively control and adjust the introduction of water and cement into the first mixer and the introduction of further water into the cement mixer.

A method performs evaluation of properties of a clay rod, with which a honeycomb structural body is produced. The method mixes raw materials to produce a clay, and extrudes the clay and compresses the extruded clay to produce a clay rod. The method performs NMR to detect at least one of a T1 relaxation time and a T2 relaxation time in each of a normal part and an abnormality part extracted from the clay rod. Each of the T1 relaxation time and the T2 relaxation time corresponds to a relaxation time of nuclear spins of water protons magnetically excited in each of the normal part and the abnormality part. The method performs the evaluation of uniformity of a mixed state and a compression state of the clay rod based on a difference in T1 relaxation time and T2 relaxation time between the normal part and the abnormality part.

A bucket assembly for a construction vehicle, having a body with a bottom wall, a rear wall, a first side wall, and a second side wall defining a cavity therein, the first side wall having a discharge outlet. A metering system includes an auger moveably attached to the body along a pivot axis within the cavity. The auger has a motor end and a discharge end. A motor engages with the motor end of the auger and is configured for variable movement of the auger about the pivot axis in a first direction for metered dispensing of a construction material through the discharge outlet, and a second direction for controlled mixing of the construction material within the cavity.

An apparatus (1) for producing fluid concrete comprising: a first mixer (100) configured to mix at least water (A1) and cement (C) so as to make a low fluidity concrete (2), having consistency class S2, a truck mixer configured to mix the low fluidity concrete (2) with further water (A2) so as to make a fluid concrete (3) having consistency class S2, a water supply means and at least a cement supply means configured so that said apparatus (1) can produce fluid concrete (3), a control and adjustment unit (4), connected to the water supply means and at least to the cement supply means, configured to selectively control and adjust the introduction of water (A1) and cement (C) into the first mixer (100) and the introduction of further water (A2) into the cement mixer.

The invention discloses an automatic processing irrigation truck for concrete pier for bridge pier, and includes a body plate, a bottom plate is fixed on the end surface of the body plate, and a storage block is fixed on the right side of the end surface of the bottom plate. A processing mechanism is provided in the storage block, and the processing mechanism includes a stirring cavity with an opening facing upward. The agitating chamber is used for containing concrete. The agitating chamber is provided with a rotatable drive shaft. Ten ten agitating rods are evenly fixed on the drive shaft. The device can be used for bridge pier during transportation. The processing of concrete, by means of stirring and spiral circulation, can not only make the processing fully, but also prevent the subsequent layering of the concrete, ensure the quality of the concrete, and use spiral transportation when needed.
