Abstract
A container is provided for slurry; an impeller is provided to effect slurry movement in the container; and a vibrator is operated for transmitting sufficient vibration to the moving slurry to lower the water/cement ratio to a low level, and at a water temperature within a specified range. The location of vibration transmission from the vibrator can be adjusted along the wall of the container.

The method of treating an aqueous, cementitious slurry, the slurry consisting essentially of water and Portland cement, that includes:
- a) providing a container for the slurry and effecting movement of the slurry, in the container, and
- b) transmitting sufficient vibration to the moving slurry to lower the water/cement ratio to about 0.30 for water temperature from below 100.degree. F. up to 190.degree. F., to enhance fluidity of the slurry.
The method of treating an aqueous, cementitious slurry, to enhance fluidity, that includes:
- a) providing a container for the slurry and effecting movement of the slurry, in the container, and
- b) transmitting vibration to the moving slurry,
- c) the container having a wall adjacent which the slurry moves, and said vibration is transmitted to the slurry via the wall,
- d) adjusting the location of said vibration transmission via said wall, said adjusting including shifting the location of said vibration transmission, along said wall, and
- e) and including providing a channel adjacent the wall at the side thereof opposite the slurry, and shifting the location of said vibration transmission along the channel.
The method of treating an aqueous, cementitious slurry, to enhance fluidity, that includes:
- a) providing a container for the slurry and effecting movement of the slurry, in the container, and
- b) transmitting vibration to the moving slurry,
- c) said movement of the slurry being effected in a swirling and downwardly flowing pattern, said vibration being transmitted to the swirling slurry,
- d) inducing said swirling via a rotating impeller toward and into which the slurry flows, downwardly,
- e) and including also stirring the slurry, in the swirl direction of rotation, at a location immediately above the impeller, and in the path of slurry flow toward the impeller.
In apparatus for treating an aqueous, cementitious slurry, the slurry consisting essentially of water and Portland cement, the combination that includes:
- a) a container for the slurry and means effecting movement of the slurry, in the container, and
- b) vibrator means coupled with the container and operated at a frequency for transmitting sufficient vibration to the moving slurry to lower the water/cement ratio to about 0.30 for water temperature from below 100.degree. F. up to 190.degree. F. and to enhance fluidity of the slurry,
- c) the slurry consisting essentially of water and Portland cement, and sufficient vibration being transmitted into the moving slurry to lower the water/cement ratio to about 0.30 for water temperature from below 100.degree. F. up to 190.degree. F.
In apparatus for treating an aqueous, cementitious slurry, to enhance fluidity, the combination that includes:
- a) a container for the slurry and means effecting movement of the slurry, in the container, and
- b) vibrator means coupled to the container for transmitting vibration to the moving slurry,
- c) the container having a wall adjacent which the slurry moves, and said vibration is transmitted to the slurry via the wall,
- d) and including means for adjusting the location of vibration transmission via the wall,
- e) and wherein said means for adjusting vibration transmission includes a channel adjacent the wall at the side thereof opposite the slurry, said vibrator means attached to the channel to be shifted therealong.
In apparatus for treating a aqueous, cementitious slurry, to enhance fluidity, the combination that includes:
- a) a container for the slurry and means effecting movement of the slurry, in the container, and
- b) other means transmitting vibration to the moving slurry,
- c) said movement of the slurry being effected in a swirling and downwardly flowing pattern, said other means including vibrator means for producing said transmitted vibration and which is transmitted to the swirling slurry and sidewardly thereof,
- d) and including a rotating impeller within the container and inducing said swirling,
- e) and including also stirring means for locally and rapidly stirring the slurry, at a location immediately above the impeller, and in the path of slurry flow toward the impeller.
