MAG SECTION 728

• SAMPLING (D 4832, should be D 5971)
• CONSISTENCY TESTING
• slump (C 143) effect of rodding ?
• flow (D 6103) minus ¾ in. fraction, measure
  spread using 3 x 6 cylinder

MAG 728 COMPRESSIVE STRENGTH

• ASTM D 4832
• Typically, split 6 x 12 in. plastic cylindrical
  molds
• No consolidation required
• Transportation to laboratory at 4 days, may have
  to be delayed further
• Difficult to handle ½ - sack CLSM specimens
