1. General This apparatus is used in the test to determine the bleeding rate and bleeding capacity of cement paste and mortar by a direct and continuous procedure. 2. Unpacking The Cement Bleeding Apparatus, Model H-3600 consists of a container for the paste or mortar to be tested, a collecting ring and a measuring burette with funnel. For shipment, the apparatus is disassembled to avoid breakage during transit. Care should be taken in unpacking to be sure no parts are overlooked. 3.
CAUTION: The bleeding tests should be run in a well-ventilated room. Take care to avoid spilling carbon tetrachloride and breathing the vapors. Keep the exposed portion of the liquid surface around the funnel covered during the test. 4.3 VIBRATION: Place the bleeding apparatus in a draft-free location and set it on a sponge rubber mat or equivalent that will serve as a vibration damper. 4.4 Notes: Approximately 500 ml of carbon tetrachloride are required per test.
5.2 Calculate the bleeding capacity as follows: Bleeding capacity, cu cm per cu cm = V2/V3 Where, V2 = total volume of bleeding water, in cubic centimeters, and V3 = volume of the cylinder of paste or mortar under the collecting ring, in cubic centimeters. 5.3 Calculate and report bleeding rate and bleeding capacity values to the nearest three significant digits. Warranty Humboldt Mfg. Co. warrants its products to be free from defects in material or workmanship.
