The initial base diameter of a flow mold

WebBeam mold dimension--the length must be at least 2 inches greater than three times the depth (ex. if depth is 6", length must be 20" min.). Width must not exceed 1.5 times the depth (ex. depth is 6", width can be 6" to 9" max.). Unless specified by the project, depths and widths must be at least 6 inches. When planning to mold and cure concrete ... WebIt should be noted that before the initiation of the 25 drops of the flow table the spread diameter was 100 mm only, equal to the bottom diameter of the flow cone. This means that the fresh mixture was almost a zero-slump mix. The initial and final setting times were measured to be 142 and 284 minutes, respectively.
