A test for the consistency of concrete using the penetration of a half sphere
| Description | |||
| A test for the consistency of concrete using the penetration of a half sphere; a 1-inch (2.5-centimeter) penetration by the Kelly ball corresponds to about 2 inches (5 centimeters) of slump. Determines depth of penetration of metal weight into plastic concrete. Apparatus consists of 30 lb. (14kg) cylinder with hemispherically shaped bottom and handle. The stirrup (frame) guides the handle and acts as a reference for measuring depth of penetration. Handle is graduated in 1/4" (6.4mm) increments on one side and half-centimeter increments on the other side. Concrete may be tested as placed in the forms prior to any manipulation or in a suitable container. 20lb version can be used with lightweight concrete. Complies with California Test Method CTM533; AASHTO T183; ASTM C360. Shipping wt. 40 lbs. (18kg) | |||
