| 4686852 | Method of preparing mortar or concrete A method and apparatus of measuring water percentages of a fine aggregate comprising the steps of prewetting the fine aggregate, containing the prewetted fine aggregate in an air-tightly closed container, applying a centrifugal force to said container ove... | 08/18/1987 |
| 4566799 | Apparatus for adjusting the quantity of liquid deposited on fine granular materials and method of preparing mortar or concrete The quantity of water on the surface of sand particles is reduced by applying an impact force, e.g. centrifugal force created by a rotating disc. The sand particles thus treated are especially suitable for preparing a green concrete compound or a cement m... | 01/28/1986 |
| 4547975 | Method and apparatus for adjusting the quantity of water deposited on a fine aggregate A quantity of water deposited on sand particles is adjusted to a predetermined value by utilizing a method and apparatus disclosed having a hopper through which the sand particles to be treated are supplied. A velocity energy is imparted to the particles ... | 10/22/1985 |
| 4492478 | Method and apparatus for applying mortar or concrete One of ingredients of green concrete are supplied to a rotary disc through a central tube by a pump or low pressure air and the other ingredient is supplied to the rotary disc from a hopper by a screw conveyor. These ingredients are mixed together on a ro... | 01/08/1985 |
| 4431310 | Method of preparing kneaded compositions In the preparation of a cement paste about 30 to 76% of the total water is added to the cement to form a funicular state, capillary state or slurry state, and the resulting mixture is kneaded so as to reduce the coagulated lumps of cement. Then the remain... | 02/14/1984 |

| 4337020 | Method and apparatus for manufacturing articles of hydraulic substances A plurality of moulds each including a side frame and a hollow bed overlying the side frame are vertically stacked with sealing members interposed between the beds and the side frames for hermetically sealing the moulds. While the pressure in the moulds i... | 06/29/1982 |
| 4299633 | Method of preparing green compositions containing a hydraulic substance and method of utilizing the same A green concrete mortar is prepared by the steps of preparing a first composition in which water is uniformly deposited about the particles of sand, preparing a second composition consisting of a powder of cement, mixing together the first and second comp... | 11/10/1981 |
| 4292351 | Method of blasting concrete A slurry shaped freshly mixed fluid compound such as paste or mortar and coarse or fine aggregate are conveyed under pressure through discrete conduits and then mixed together substantially immediately before blasting. The mixture is blasted through a noz... | 09/29/1981 |
| 4234534 | Method and apparatus for manufacturing articles of hydraulic substances A plurality of moulds each including a side frame and a hollow bed overlying the side frame are vertically stacked with sealing members interposed between the beds and the side frames for hermetically sealing the moulds. While the pressure in the moulds i... | 11/18/1980 |
| 4143541 | Method and device for measuring the characteristics of plastic fluid and control system for pouring the same into moulds The fluidity of a plastic fluid, cement mortar for example, is measured by passing the fluid through a flow passage packed with an aggregate for simulating an actual mould, measuring the flow pressure, and measuring the quantitative flow coefficient betwe... | 03/13/1979 |
